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
Narration Box
Narration Box is a voice production platform for creators and teams, covering text to speech across 1,500-plus narrators and 80-plus languages, voice cloning from 30 seconds, and an audiobook creator that parses EPUB, PDF and DOCX files into chapters with per-narrator assignment and per-passage regeneration.
- Block-level regeneration solves the specific problem that kills long-form projects
- Parsing a manuscript into chapters removes hours of clerical work
- Chapter audio output matches what distribution platforms expect
- A base delivery plus exception tags is how a human narrator actually works
- No stated consent verification for voice cloning
- Whether a pronunciation lexicon persists across a project is unstated
- Fifteen hundred voices is more than anyone can meaningfully browse
