Chatterbox
Open-source text-to-speech with zero-shot voice cloning Category: Video & Audio.
- Completely free under a permissive MIT license
- High-quality cloning with minimal reference audio
- Can be self-hosted with no usage caps or royalties
- Zero-shot voice cloning from short reference audio
- Requires technical setup and a capable GPU
- Less approachable for non-developers than hosted services
- Mobile experience can lag the desktop workflow
Phonely AI
Phonely AI builds AI agents that handle phone calls, chat and SMS at scale. Its own model, Alma, is quoted at 182ms to first token against 490ms for GPT-4.1, with 1,000+ voices, 100+ languages and SOC 2, HIPAA and PCI compliance.
- Latency is the right thing to optimise for, and building an own model for it is a coherent bet
- Turn-taking as a named feature addresses what actually gives agents away
- HIPAA and PCI coverage opens sectors most voice AI simply cannot enter
- Completing bookings and CRM updates ends the call with an outcome, not a promise
- The headline latency figures are the vendor's own and unverified here
- Voice quality is now table stakes, so 1,000+ voices is less differentiating than it looks
- Complex, emotional or high-value calls still belong with people
