Noiz AI
Noiz AI is a speech platform combining text to speech with emotion control written directly into the script, voice cloning from about three seconds of audio, voice design from a text description or a character image, sound design and one-click video dubbing that preserves the original voice.
- Inline emotion tags let a passage turn where a performance would
- Direction is exposed as script syntax rather than as a single mood setting
- Voice design from a character image matches how casting actually works
- The library is tagged by use case rather than only by name
- Three-second cloning removes the practical consent barrier entirely
- No stated consent verification for cloning someone else's voice
- Whether a designed voice persists as a reusable asset is unclear
