HeyGen Voice is HeyGen's first in-house AI voice model, announced October 9, 2026. For most of HeyGen's history the voice came from a third-party engine and HeyGen moved the avatar's mouth to match; HeyGen Voice closes that seam by generating the voice inside the same end-to-end stack that drives its Avatar V model. The pitch is identity: a video's face and voice are produced from one system, so a persona sounds like itself across clips instead of being stitched from separate vendors.
What makes it notable is the quality claim and the price. HeyGen says the model debuted at #1 on Artificial Analysis' independent voice leaderboard, and CTO Rong Yan framed the point as "you don't have to trade authenticity for quality" — the model is built to preserve emphasis, emotion, and timing, the components that make a voice sound human rather than flatly synthetic. The base HeyGen Voice model is free within the HeyGen platform and its API, which is aggressive for a model that launched at the top of a leaderboard.
On top of the free base, HeyGen Professional Voice Clone is a $99/month add-on that trains a clone of your own voice — with your explicit consent — on roughly 30 minutes to three hours of your recorded speech, for a closer match than the stock model. HeyGen says it requires that consent and builds safeguards into its products so a person stays in control of how their voice and likeness are used.
The honest framing: HeyGen Voice is a voice model, not a content operation. It produces a voice track (and, paired with avatars, narrated video) and stops there. Nothing in it captions that audio for muted feeds, reframes a clip per platform, writes a caption in your brand voice, or schedules a post. It is also one day old at this writing, so its leaderboard placement is a cloned-voice snapshot rather than a long record of real-world use — judge it on your own script before you rebuild a workflow around it.
HeyGen Voice is best understood as an *input*, not an output — and that reframes how a creator should use it. You are not adopting a new standalone tool to babysit; you are getting a better-sounding, identity-matched voice that something downstream turns into posts. The question a free voice forces is simple: once the audio is perfect, who captions it, sizes it for nine feeds, writes the thread and the blog in the same voice, and puts it on a schedule? That is the entire job [Kompozy](/) exists to do, and HeyGen's voice layer plugs straight into it.
Concretely, Kompozy already generates HeyGen avatar video inside its [Persona Shorts](/glossary/persona-shorts) and Persona HeyGen formats, which use HeyGen's voice and avatar — so the voice HeyGen just upgraded narrates a Kompozy render that is then auto-captioned for silent autoplay and reframed to 9:16, 1:1, and 16:9. From there one script fans out: the same idea becomes a brand-exact [Carousel via HyperFrames](/glossary/hyperframes), a Quote Graphic, an [Infographic Photo](/glossary/output-buckets), a Blog Article, and an Email Newsletter — and the [Persona Brief](/glossary/persona-brief) keeps the *written* voice matching the *spoken* one HeyGen Voice produces. [Autopilot](/glossary/autopilot) then schedules the whole set across the eight social platforms plus blog and email behind a per-post review gate. HeyGen gave your persona a free, consistent voice; Kompozy is the engine that turns that voice into a week of finished, on-brand posts instead of an audio file in a folder.

The base HeyGen Voice model is free within the HeyGen platform and its API. A separate add-on, HeyGen Professional Voice Clone, costs $99/month and trains a clone of your own voice — with explicit consent — on roughly 30 minutes to three hours of your recorded speech.
HeyGen says HeyGen Voice debuted at #1 on Artificial Analysis' independent voice leaderboard, a result drawn from a cloned-voice comparison. It launched October 9, 2026, so that is a point-in-time snapshot rather than a long track record; ElevenLabs has far more independent testing. Compare them on your own script and language before switching.
No. HeyGen Voice generates the voice (and, with avatars, narrated video); it does not caption, reframe, repurpose, or schedule anything. Kompozy generates HeyGen avatar video narrated by HeyGen's voice, then auto-captions it, fans the idea into other formats, and publishes across the eight social platforms plus blog and email behind a per-post review.
Yes. HeyGen says it requires the voice owner's explicit consent to train a Professional Voice Clone, and it builds safeguards into its products so a person stays in control of how their voice and likeness are represented.
