HeyGen Launches Professional Voice Clone, Enabling Studio-Quality AI Voice Replication with 20+ Minutes of Audio

HeyGen has released Professional Voice Clone through its API, a new feature that creates high-fidelity synthetic voices trained on users' own speech recordings. Available as a $99/month add-on, the feature requires a minimum of 20 minutes of audio—ideally 30 minutes to 2+ hours—and promises to preserve the speaker's unique vocal characteristics including breath, pauses, laughs, and accents.
