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
PolyAI
PolyAI is an enterprise platform for building and governing voice agents, powered by Raven, a proprietary model it states was trained on over a billion enterprise conversations, with a frontier dialog model called Dialog-RSN-1 and published customer outcomes across health, hospitality, retail and delivery.
- Targets the hard calls rather than the demo-friendly ones
- Dialog-native architecture addresses the actual failure modes of voice
- Publishes model benchmarks in a category that usually shows only demos
- Two build surfaces over one runtime keeps business and engineering aligned
- Outcome figures are single-customer results, not typical performance
- The Forrester study is commissioned research rather than independent audit
- Benchmarks are vendor-constructed, and dialog evaluation resists standardisation
