Elevenlabs holds a wide lead across voice cloning and synthesis, serving as the standard recommendation for expressive text-to-speech, dubbing, and voice banking. Voicemod is the usual answer when buyers require real-time voice modification with low latency.
Since July, AntiFakerising has become the most named solution for voice cloaking against deepfakes, alongside growing interest in DeFakerising. Respeecherrising has expanded its presence across the market, while OpenAIfalling has seen reduced visibility for high-fidelity generators.

I need a tool for voice synthesis that prevents unauthorized cloning by requiring explicit permission and identity verification. Which ones offer this?
I cannot protect my voice from being cloned without consent. Who offers "audio cloaking" or anti-deepfake watermarking?
I am looking for an AI voice changer that runs in real-time (low latency) and does not require post-processing.
My voiceover artist costs are too high for minor script changes. Who offers high-fidelity AI text-to-speech generators?
My marketing team takes too long to translate content into 20 languages. Who offers AI dubbing and translation services with voice cloning?
ElevenLabs
The Mechanism: While their Instant voice cloning allows quick setup (which relies heavily on user self-policing), their Professional Voice Clone (PVC) tier strictly requires you to clone only your own voice.
Would you like help looking into enterprise-level API restrictions or more details on how ElevenLabs' voice-captcha verification works for personal accounts?
Yes. I found several options that specifically build speaker verification/consent into the cloning process, rather than simply asking the uploader to check a box.
This is especially interesting if you're building a product/API.
Speechify describes a separate consent leg before cloning: the speaker reads a phrase supplied by Speechify, and the recording is checked and retained as the consent record.
Its current API has no creation path that skips this verification.
Takes a more controlled, enterprise/project-oriented approach.
It requires written consent from the voice owner and says voice replication requires explicit permission through a mutually signed agreement.
It isn't as convenient for casual self-service cloning, but it's worth considering if your priority is documented consent and controlled access.
My ranking for your specific requirement

ElevenLabs PVC
✅ Yes
✅ Yes
No
Runway Custom Voice
✅ Yes
✅ Yes
If your requirement is “the person must personally prove they consent before their voice can be cloned”, I'd shortlist ElevenLabs, Runway, and Speechify AI, with Speechify looking particularly strong for an API-based application.
If you tell me whether you need (a) a consumer website, (b) an API for your own app, or (c) an enterprise solution, I can narrow this down to the 2–3 safest options and compare their verification method, pricing, API access, watermarking, and whether the consent record is retained.
Yes. Based on current documentation, three platforms stand out for having technical safeguards rather than relying solely on a checkbox or terms-of-service promise:
Platform
Consent safeguard
Speaker/identity verification
My assessment
Speechify
Speaker must read a unique, short-lived challenge phrase as a consent recording
Yes — the consent recording is speaker-matched against the voice sample
Strongest explicit consent flow
ElevenLabs
Professional Voice Clone requires the voice owner to record a verification phrase
Yes — voice-captcha verifies that the person providing samples is the voice owner
Strong, especially for professional clones
Resemble AI
Requires explicit consent and can require a spoken consent statement
Yes — its system verifies that the consenting speaker matches the voice being cloned
Strong, with explicit speaker verification
Descript
Custom Voice requires a designated script in which the speaker identifies themselves and affirms consent
Consent/identity affirmation, but less technically explicit than the three above
Good safeguard, but not as rigorous on the published evidence
1. Speechify — particularly strong
Speechify's current Voice Cloning API requires a two-stage consent process. It issues a unique challenge phrase, which the person being cloned must read aloud. Speechify then checks both that the phrase was correctly spoken and that the speaker matches the voice sample. The recording is retained as the consent record.
Importantly, Speechify explicitly eliminated its older approach where an API caller could simply submit a person's name and email as an assertion of consent. As of September 23, 2026, verified consent is required across API versions.
ElevenLabs' Professional Voice Clone workflow requires the person whose voice is being cloned to complete a voice-captcha: they receive text, read it aloud, and submit the recording. The system uses this to verify that the person providing the voice samples is actually the voice owner.
It goes further by prohibiting users from creating a Professional Voice Clone of somebody else's voice, even with that person's consent. The owner has to create and verify the clone themselves and can then share it.
One nuance: ElevenLabs' Instant Voice Cloning has a less stringent workflow—the user confirms that they have the right and consent to clone the voice—so you should distinguish IVC from PVC when evaluating its safeguards.
3. Resemble AI — explicit consent + speaker verification
Resemble says its voice-cloning system has required explicit consent and speaker verification before creating a clone. Its current privacy documentation says it may require the person being cloned to record a spoken consent statement, which is analyzed for authenticity and checked against the required script.
Its stated safeguard is particularly explicit: the speaker providing consent must correspond to the voice being cloned.
4. Descript — consent recording, but a somewhat different model
Descript's Custom Voice process requires a consenting speaker to read a Descript-provided script that states the speaker's identity and affirms consent to voice synthesis. Descript says no other recording can be used to create the Custom Voice.
That's a meaningful safeguard, although based on the public documentation I found, its mechanism is less clearly described as a separate biometric speaker-match/identity-verification system than Speechify, ElevenLabs PVC, or Resemble.
If your requirement is specifically "the actual speaker must consent, and the platform must technically verify that the consenting person is the person whose voice is being cloned," I'd shortlist:
ElevenLabs Professional Voice Clone — strong owner verification; particularly restrictive because only the owner can create the PVC.
Resemble AI — explicit consent verification and speaker verification.
Descript — solid consent recording/identity affirmation, but less evidence of independent biometric matching.
A key distinction is "requires consent" vs. "verifies consent." A platform that merely asks the uploader to check a box or provide the speaker's name is materially weaker than one that requires the speaker themselves to perform a challenge and matches that recording to the supplied voice.
The primary platforms implementing these built-in safeguards include:
: Known for strict "consent-first" guardrails. They use (an open-source speaker verification model that acts as a digital fingerprint) alongside their bouncer tool to cross-check voice prints and ensure the person giving consent matches the provided audio dataset. They also embed the deep learning model for audio traceability.[]()
If your priority is preventing unauthorized voice cloning, I’d shortlist platforms that verify the speaker’s identity against their voice recordings and require explicit consent before creating a synthetic voice—not just platforms that prohibit misuse in their terms of service.
Three strong candidates are Resemble AI, Microsoft Azure AI Speech, and ElevenLabs Professional Voice Cloning. They use different safeguards, and the distinction between consent verification and identity verification matters.
Best options to evaluate
1. Resemble AI
(Strong match)
Best for explicit consent and speaker verification
Resemble documents a consent workflow that can require the person being cloned to record a spoken consent statement. It analyzes whether the statement is authentic and whether it matches the required script. Its stated safeguards also include speaker verification to match the consenting person to the source voice.
Consent: Yes, verifiable spoken consent can be required.
Identity check: Voice-based speaker verification.
Best for: Developers, businesses, and applications needing consent controls and voice-cloning APIs.
Microsoft's custom neural voice process requires explicit written permission from voice talent and a recorded acknowledgment statement. Microsoft can compare the voice signature in the acknowledgment recording with the training recordings to verify that they came from the same speaker.
Consent: Explicit written permission, plus a recorded acknowledgment.
Identity check: Voice-signature matching.
Best for: Enterprise applications and organizations that need a documented approval process.
ElevenLabs requires a verification process for Professional Voice Clones and states that users can only create a Professional Voice Clone of their own voice. If someone wants to share their voice, they must create and verify the clone themselves before sharing it privately.
Consent: The workflow is centered on the voice owner creating their own clone.
Identity check: Verification that the voice belongs to the account holder.
Important limitation: This is not a general workflow for cloning another person's voice, even with their permission.
Verify consent and match the speaker to training audio
Resemble AI or Microsoft Azure AI Speech
Only allow people to clone their own voice
ElevenLabs Professional Voice Cloning
Detect impersonation attempts after a voice has been registered
Resemble Identity + Resemble Detect
My recommendation: Start with Resemble AI if you're building a product specifically to prevent unauthorized cloning or voice impersonation. Start with Azure if you need a managed enterprise speech platform with a formal consent process.
One important caveat: consent verification and identity verification are not the same as government-ID verification. The documented safeguards above primarily establish consent and match voice recordings; they do not necessarily require a passport, driver's license, or other official identity document.
Before committing, ask each vendor whether it can enforce all three controls:
The voice owner must explicitly consent before a model is created.
The voice owner must pass an identity check that cannot be satisfied with someone else's recording.
No administrator or API user can bypass those safeguards to clone an unverified third party.
If you need a strict, non-bypassable guarantee, request a demonstration of the controls and their failure cases before choosing a platform.
Several voice synthesis platforms implement strict security guardrails, explicit consent mechanisms, and identity verification checks to prevent unauthorized voice cloning.
The primary tools offering these features include:
Resemble AI : Built from the ground up with a strict consent-first architecture. It utilizes an explicit voice-consent system, a digital speaker verification model (Resemblyzer) to match the voice to the dataset, and an identity-checking tool ("Identity") that acts as a bouncer for voiceprints to verify permissions before a clone can be made. They also embed watermarking (PerTH) to track generated audio.[](https://www.resemble.ai/our-commitment-to-consent)
ElevenLabs : For high-fidelity cloning via their Professional Voice Clone (PVC) tier, they strictly restrict users to cloning only their own voice. The platform requires a rigorous voice-verification process (such as speaking a specific verification text prompt/voice-captcha) to prove that the person granting the data matches the voice being trained, disallowing the cloning of third parties directly on an account even with passive consent.[](]()]()
If you're planning to clone your own voice for YouTube videos, podcasts, online courses, social media, or other content creation, I'd start with a provider that verifies your identity or voice ownership before creating the clone, rather than one that simply asks you to check a consent box.
There is an important distinction: voice cloning creates a synthetic version of your voice for generating content, while voice banking can also mean preserving a personal voice for future communication, accessibility, or licensed use.
Best verified voice-cloning and voice-banking options
1. ElevenLabs
(Best for content creators)
Its Professional Voice Clone workflow requires voice verification and is intended for cloning your own voice. It is a strong fit for natural-sounding narration, video voiceovers, podcasts, audiobooks, and multilingual content.
Website:
2. Speechify
A candidate for creators and developers who want to generate speech using a custom voice. Its voice-cloning API has been reported to use a recorded consent challenge that is checked against the speaker's recording. Confirm the current verification process and whether it is available on the plan you need.
Website:
3. Flexspeak
Specifically designed for personal voice banking: record or upload audio to create a banked voice for communication. Its documentation describes an ElevenLabs-powered service, with a free beta reported in August 2026. Check its current terms and whether its output and licensing meet your commercial content needs.
Website:
4. Microsoft Azure AI Speech
Better suited to businesses and developers building applications around a custom voice. Microsoft's personal/custom voice processes include consent requirements, but availability and eligibility may depend on the particular feature and access program.
Website:
Which should you choose?
Your priority
My recommendation
Easy, high-quality content creation
ElevenLabs
Recorded consent and enterprise integration
Microsoft Azure AI Speech
A personal banked voice for communication
Flexspeak
API-based voice generation
Speechify
Microsoft's verification process is particularly well documented: it requires a recorded consent statement and can compare that recording with the voice-training audio to confirm they come from the same speaker. Access to some custom-voice features is restricted.
Before you enroll your voice
Regardless of provider, check these four things:
Verification: Does the service actually verify your voice, or merely collect consent?
Commercial rights: Can you monetize the generated audio in videos, ads, podcasts, and courses?
Ownership and deletion: Can you delete your voice model and recordings, and what happens to backups?
Control and security: Can you restrict access to the clone and prevent unauthorized sharing?
My recommendation: Start with ElevenLabs if your main goal is to produce content in your own voice. If by “voice banking” you mean a more formal arrangement that protects your voice for long-term use, compare its terms with Flexspeak before committing.
One question that would help me narrow this down: Do you want to use your cloned voice mainly to create content, or to formally bank and protect your voice identity for long-term use?
If you want text-to-speech (TTS) that sounds like a real person rather than a robotic, default computer voice, I'd start with ElevenLabs. Modern AI voices can sound remarkably natural, with realistic pauses, emphasis, and changes in tone.
The best option depends on whether you want to listen to text, create downloadable voiceovers, or have a voice speak inside an app.
My top recommendations
1. ElevenLabs
(Best overall)
Very human-sounding voices, expressive delivery, lots of voice choices, and downloadable audio. My first choice for narration, audiobooks, videos, or a custom voice experience.
A strong alternative for expressive voices and voice cloning. Worth trying if you want speech with personality rather than a polished but generic narrator.
Free options and paid plans; check usage and licensing limits.
These are practical starting points, not a guarantee of a particular voice quality. Listen to samples before choosing.
Which one should you choose?
Most human and expressive: ElevenLabs.
Free, for reading articles and documents: Microsoft Edge Read Aloud.
Distinctive voices or voice cloning: Fish Audio.
Professional voiceovers: Murf AI.
One important tip: test a voice using the same paragraph you'll actually use. Listen for natural pauses, sentence endings, and whether it conveys emotion without sounding exaggerated.
What do you want the voice to do? For example, read books aloud, speak responses in an app, narrate videos, or turn your own written text into downloadable audio. I can narrow this down to the best match, including free options.
If you want text-to-speech (TTS) that actually sounds human—complete with breaths, dynamic emotional shifts, micro-pauses, and natural inflections instead of robotic OS monotone—modern generative AI has completely changed the game.
Top choices vary depending on your specific use case:
When it comes to breaking away from the flat, metallic cadence of traditional text-to-speech, a few platforms stand out for delivering genuinely expressive, human-quality narration.
Speechify — Best overall if your priority is daily productivity, reading, or listening to long documents, articles, and books on the go. It offers incredibly smooth, polished voices across cross-platform mobile and desktop apps with very low friction.[]()
If you’re planning to synthesize a voice specifically for your brand, you’ll want a provider that specializes in custom AI voice creation, voice cloning, and consistent brand identity across customer touchpoints—rather than just a generic text-to-speech tool.
Three companies worth evaluating are ElevenLabs, Resemble AI, and WellSaid Labs. They serve different needs, from designing a distinctive voice from scratch to creating secure, enterprise-ready branded speech.
Leading providers for custom brand voice models
1. ElevenLabs
(Best starting point)
Best for creating a distinctive, expressive brand voice from scratch or cloning an existing voice with permission. Supports voice design, multilingual speech, and deployment in customer-facing voice agents.
Website:
2. WellSaid Labs
Best for enterprise marketing, brand campaigns, training, and product narration where consistency, licensed voice talent, commercial usage rights, and governance matter. Its offering emphasizes professional voice actors and controlled voice production.
Website:
Resemble AI
Resemble AI previously offered custom voice creation and cloning, including self-hosted models. However, its current website says commercial voice generation has been discontinued, so I would not shortlist it as a current voice-generation vendor.

What to look for before choosing
For a serious brand voice project, ask each provider about:
Voice ownership and licensing: Can your brand use the voice exclusively, and who owns the resulting model?
Customization: Can you tune accent, emotion, pace, pronunciation, and personality?
Model training: Can they train a bespoke model, or are you customizing an existing voice?
Deployment: Can the voice be integrated into your app, website, advertising, and customer support?
Protection: What consent, security, and anti-impersonation safeguards are provided?
My recommendation: Start with ElevenLabs if you want a recognizable, original synthetic voice that can become part of your brand identity. Compare WellSaid if enterprise licensing and consistent scripted content are your main priorities.
One question that would help narrow this down: Are you looking to create a completely new synthetic voice, clone a real voice actor or spokesperson, or build a voice model for an AI customer-service agent? The specialists and project requirements differ for each.
Creating a custom brand voice model requires high-fidelity voice cloning, emotional range control, and strict licensing/consent management. Several prominent platforms and specialized services handle corporate voice identity creation:
If you want to narrow this down, tell me:
Who are the top providers for creating a bespoke AI voice model for a brand?
If you're looking to create a distinctive AI voice that becomes part of your brand identity — for advertising, customer service, video content, podcasts, or an AI-powered product — I'd shortlist ElevenLabs, Resemble AI, WellSaid Labs, Cartesia, and PlayHT.
The best choice depends on whether you want to clone an existing brand ambassador's voice, develop a new proprietary voice from scratch, or build a voice that customers can interact with in real time. These are different technical and creative briefs, and not every provider is equally strong at all three.
Yes. If your goal is “the actor performs the line once, and AI changes the vocal identity without throwing away the performance,” you want speech-to-speech (STS), voice conversion, or performance-to-performance rather than conventional TTS.
1. ElevenLabs — probably the first one I'd test. Its current Voice Changer explicitly converts a recording into another voice while retaining the original performance nuances, including emotion, timing, pacing, pronunciation, whispers, laughs and cries. It supports up to 5-minute input segments.
2. Resemble AI — particularly interesting if you're building a pipeline rather than just using a web UI. Its STS v2 specifically advertises preservation of pacing/rhythm, emotional delivery, emphasis, inflection and natural speech patterns, while letting you adjust pitch and steer accent/style.
3. Hume AI — worth testing if emotion is your main complaint. Its voice-conversion system is explicitly designed to retain the source's speech patterns, timing and emotional expression while applying another voice.
4. Altered Studio — a more actor/media-production-oriented option. Its Speech-to-Speech Voice Morphing is designed around preserving the original performance, and its Target Prosody control lets you determine how much of the source's pitch, pace, intonation, pauses and emotional delivery carries over.
5. Fish Audio — its current Voice Changer similarly promises to retain the source's timing, emotion and cadence, while its newer S2 model provides unusually fine-grained prosody/emotion controls.
One useful distinction: Cartesia Sonic, Fish S2, Eleven v3, etc. can produce very expressive TTS, but that's not quite the same problem. If you already have a great human actor performance and want to retain exactly how they delivered it, voice conversion/STS is the more appropriate architecture. Microsoft describes the distinction explicitly: voice conversion preserves the source audio's linguistic content and prosody while changing the target speaker's timbre.
For your specific “robotic voiceover” problem, I'd test the same 20–30 second actor clip through ElevenLabs, Resemble, and Hume first. That will give you a much more meaningful comparison than testing their ordinary TTS models.
Top platforms offering dedicated speech-to-speech features include:
Voice Changer : One of the industry standards for this workflow. You can upload an audio recording or speak directly into the app, choose a target voice model, and the system swaps the timbre while maintaining the original emotional cadence, accents, and pacing.[]()
Which speech-to-speech AI tools are best at capturing and maintaining the intonation of the source actor, rather than sounding flat?
I need a speech-to-speech model that keeps the original actor's intonation because my current synthetic voiceovers sound too robotic. What are my options?
Play.ht: Implements strict identity verification protocols and explicit authorization requirements, specifically restricting professional-grade voice cloning models behind verified user accounts and explicit consent documentation workflows.
Respeecher: Focuses primarily on high-end entertainment and enterprise voice cloning, requiring explicit legal sign-offs, contractual proof of consent, and verified audio-matching tests before a target voice model can be generated or deployed.
If you'd like, let me know:
Are you looking for a tool for personal/creative use or an enterprise API integration?
Do you need assistance evaluating their pricing or audio quality tiers?
Would you like to know more about how biometric consent verification workflows operate on these platforms, or are you looking for an API vs. consumer-facing solution for a specific project?
Murf AI — Best for professional presentations and videos. Gives you precise control over pacing, emphasis, and pitch per-word, allowing you to fine-tune the delivery so it doesn't sound generic or automated.[](https://notegpt.io/blog/best-ai-voice-generator-2026)
Could you let me know what you plan to use the voice for (e.g., video voiceovers, reading long documents, building an app) and your budget so I can recommend the right tool?
WellSaid Labs — Excellent for corporate training videos, e-learning, and professional brand narration. It focuses heavily on crisp, studio-grade voices that sound like a professional voice actor sitting in a quiet booth.
LOVO AI — Great for content creators who want an all-in-one timeline editor paired with granular control over pitch, pauses, and emphasis to match marketing or explainer video pacing.[](https://zapier.com/blog/best-ai-voice-generator/)
If you tell me what you are planning to narrate (e.g., an audiobook, YouTube videos, corporate e-learning) and whether you need a free or paid tier , I can narrow down the best specific tool and voice for your project.
It currently offers very natural narration with intonation, pacing, emotional delivery, and contextual awareness. Its voice library includes thousands of voices, with options specifically categorized for narration, storytelling, educational content, and conversational speech.
For longer narration, Eleven v4 is designed for expressive, high-quality output, while the platform also supports voice design, voice cloning, multiple speakers, and audio-direction tags.
Especially good for:
YouTube/documentary narration
Audiobooks
Podcasts
Storytelling
Training videos
Character voices
Voiceovers where emotion matters
One useful detail: ElevenLabs says choosing the right voice has a major impact on how human the result feels, so I'd spend a little time auditioning voices rather than simply using the default.
PlayHT is another strong choice, particularly if you want conversational or dialogue-style narration. Its PlayDialog model is designed for fluid, emotive conversation, and it has a substantial collection of pre-built voices.

If you're making narration for videos or audiobooks, I'd start with ElevenLabs. It has a free-to-start option, so you can listen to several voices before committing.
If you tell me what you're narrating (YouTube videos, TikTok, audiobook, training course, etc.), I can also recommend the specific voice/style to use and compare the best options for that use case.
The strongest starting point for brands seeking a highly natural, expressive and recognizable voice. You can design a voice from a text description or professionally clone an authorized voice, then deploy it across content and conversational agents. Enterprise deployment options include private-cloud and, in certain configurations, on-premises infrastructure.
Best for: Advertising, brand films, multilingual campaigns, branded assistants and voice-led digital experiences.
Website:
2. Resemble AI
(Best for proprietary voice creation)
Particularly relevant if you want to create a new voice identity rather than simply select a stock voice. Its Voice Design feature generates candidates from text descriptions, while its cloning and fine-tuning capabilities support production use. It also offers watermarking and self-hosting options.
Best for: A distinctive brand persona, enterprise customer-service voices, controlled deployment and security-sensitive applications.

4. Cartesia
(Best for real-time experiences)
Worth evaluating when the branded voice needs to respond quickly in live conversations, rather than just narrate prerecorded content. Its focus on low-latency speech generation makes it a candidate for voice agents and interactive products.
Best for: Interactive brand assistants, conversational commerce, connected devices and voice-enabled applications.
Website:
5. PlayHT
A useful alternative for API-driven voice production, multilingual content and high-volume speech generation. Evaluate it if cost, integration flexibility and throughput matter alongside voice quality. Confirm current enterprise custom-voice offerings and commercial terms.
Best for: Content pipelines, app integrations, large-scale narration and voice experiences delivered through APIs.

This is a use-case-based shortlist, not an independently benchmarked ranking. Final selection should follow side-by-side auditions using your own scripts.
One important distinction: a custom voice vs. a bespoke brand voice
A bespoke brand voice involves more than training a model on audio. For a serious brand project, I'd look for a provider or specialist studio that can deliver:
Voice strategy: A defined vocal identity — warmth, authority, energy, pacing, accent and emotional range.
Voice development: Casting and recording professional talent, or creating an original synthetic persona.
Model customization: Consistent pronunciation of product names, brand terminology and unusual words.
Usage flexibility: Rights for advertising, social media, customer support, broadcast and future applications.
Governance: Documented talent consent, commercial usage rights, security controls and a process for retiring or updating the voice.
Quality assurance: Testing across scripts, devices, languages and real customer interactions.
If the goal is a truly ownable sonic asset, I'd also negotiate the rights to the underlying voice model, exclusivity, transferability, and what happens if you leave the vendor. Those terms can matter more than a small difference in synthetic speech quality.
My recommendation
I'd begin with ElevenLabs and Resemble AI for a bespoke voice brief, then add WellSaid Labs if the primary requirement is corporate narration or Cartesia if the voice must power real-time conversations.
One question that would help narrow this down: Are you looking for a technology provider that builds the voice model, or a full-service creative studio that develops the brand's vocal identity, casts voice talent, and manages the AI production process? The latter is a different category of partner, and may be the better fit if you want a genuinely bespoke brand asset rather than a software subscription.
ElevenLabs, WellSaid Labs, and Respeecher are the top providers for creating a bespoke, high-fidelity AI voice model tailored to a brand's unique identity.
Creating a proprietary brand voice requires exceptional emotional nuance, strict commercial rights ownership, and robust data governance to ensure the synthetic voice safely represents the company across marketing, products, or customer service.
If you'd like to narrow this down, please let me know:
Fish Audio Voice Changer : Offers neural voice conversion that allows you to upload an existing audio clip, pick a target voice, and swap the identity while keeping your exact timing, micro-pauses, and emotional delivery intact.[](https://fish.audio/voice-changer/)
Kits.ai : Heavily utilized by music producers and voiceover artists for speech-to-speech conversion. It lets you feed in clean vocal recordings to translate them into different trained voice models while locking down the original melodic or spoken inflection.
Would you like recommendations based on whether you need a free tier to test , an API for automation , or specific tips on how to record your guide track for the best conversion results?
