AI voice conversion (also called voice to voice or an AI voice changer) turns an existing voice recording into a different voice. Unlike text to speech, it doesn't start from text. It keeps the original tone, emotion, pauses and rhythm, and only replaces the voice.
That means you can perform the lines yourself, deciding where to get excited, where to drop your voice and where to pause, then let AI switch it to the target voice. For emotional or precisely timed content like character lines, short dramas and expressive narration, voice conversion often sounds more natural than text to speech.
On Voice AI Labs, the target can be a voice you cloned or a public voice from the Voice Square. Your input can be uploaded, recorded in the browser, or picked from audio you've already generated in the Audio Library. Conversion is billed by input duration, up to 5 minutes per clip.
Converted audio is saved to your Audio Library, where you can play and download it, or add it to a Voice Project as the finished audio for a section.
