Fish Audio
Fish Audio is a voice AI platform offering text-to-speech and voice cloning through its S2.1 Pro model, with a community marketplace of over two million voices. It supports 30+ languages, clones from about ten seconds of audio, exposes REST APIs and SDKs, and open-sources earlier model generations for self-hosting.
- Open-weight releases mean self-hosting, auditing and independence from one vendor's roadmap
- Self-hosting flips the cost model above a certain volume, which no closed API allows
- Marketplace variety is far beyond any curated library
- Ten-second cloning is genuinely convenient for your own voice
- Provenance and consent for two million community voices is not addressed on the site
- Ten-second cloning lowers the barrier to misuse as much as to legitimate use
- Open releases are earlier generations, not the current flagship model
Vocode
Vocode is an open-source Python library for building voice agents on top of LLMs, with conversation abstractions, endpointing, emotion tracking and integrations across speech-to-text and text-to-speech providers. A hosted service runs inbound and outbound calls via API alongside it.
- Open source, so the code stays usable independent of the company
- Solves endpointing and streaming, the parts teams always underestimate
- Hosted service removes telephony operations for teams that want that
- Beta features labelled as beta rather than described as shipped
- The marketing site now redirects to GitHub, leaving docs as the only description
- No operating company named in the documentation footer
- HIPAA compliance is beta, which is not the same as compliant
