Speech-to-Speech for Post Production
Speech-to-speech lets you take an existing recording and re-render it in a different voice – while keeping the original timing, emotion, and delivery intact. It’s built for post-production teams who need to iterate on dialogue without going back into the booth.
When speech-to-speech beats text-to-speech
Text-to-speech generates a performance from a script – useful when there’s no existing recording. Speech-to-speech starts from real audio, which matters when the original performance (pacing, emphasis, emotional tone) needs to be preserved but the voice needs to change.
| Text-to-Speech | Speech-to-Speech | |
|---|---|---|
| Starting point | Written script | Existing audio recording |
| Preserves original delivery | No – generated fresh | Yes – timing and emotion carried over |
| Typical use | New narration, no prior recording | Redubs, voice changes, dialogue fixes |
Common use cases
- Dialogue replacement (ADR alternative) – fix a line or a full scene without scheduling a new session.
- Voice adaptation – produce another version from the original performance rather than a fresh recording.
- Fast redub iterations – try a different voice without re-recording the talent.
Stays inside your session or timeline
Speech-to-speech is available both in the audio-post workflow and in video editing. Via the native ARA2 plugin, it runs directly in Pro Tools, Nuendo, Cubase, Studio One, or Reaper – fully editable, with no export step. Via the native UXP plugin, the same speech-to-speech capability runs directly in Premiere Pro, so video editors can re-render a recorded voice into a new voice without leaving the timeline. See AI Voice for Pro Tools and AI Voice for Premiere Pro for the tool-specific workflows.
FAQ
-
What’s the difference between text-to-speech and speech-to-speech?
Text-to-speech generates a voice from a written script. Speech-to-speech transforms an existing recording into a new voice while keeping the original timing and delivery. -
Can speech-to-speech replace traditional ADR?
For many revisions and dialogue fixes, yes – it removes the need to re-book talent or re-record a scene for smaller changes. For full replacement performances, teams typically combine it with traditional ADR as needed. -
Does the original emotion and pacing carry over?
Yes – that’s the core difference from text-to-speech: the source recording’s delivery is preserved in the new voice. -
Is speech-to-speech available in Premiere Pro, or only in DAWs like Pro Tools?
Both. Speech-to-speech works natively in Pro Tools, Nuendo, Cubase, Studio One, and Reaper via the ARA2 plugin, and in Premiere Pro via the native UXP plugin. - Is speech-to-speech output licensed the same way as other VoiceWunder voices?
Yes. With any paid plan, speech-to-speech output can be used commercially and royalty-free. Commercial rights remain valid after cancellation or downgrade. Only Voice Sharing voices are licensed individually – usage terms are negotiated directly between the studio and the voice talent for each project. The free Community plan is for non-commercial use only. See Licensed AI Voices for the details.
