Alternatives to Fish Audio
Open-weight AI text-to-speech and voice cloning platform with a low-cost API
Fish Audio ranks #8 of 10 in AI voice generation, with an Alt Score of 85. It is available on the web. 8 of 9 checklist rows are verified against a public source.
Fish Audio is a text-to-speech and voice cloning platform built on the open-weight Fish Speech / OpenAudio models, cloning a voice from a short reference sample across 80+ languages. It targets developers and indie creators who want ElevenLabs-level quality with an API priced far below incumbents.
Developers and businesses building voice AI products—chatbots, virtual assistants, audiobooks, games, and localized/dubbed content—who need text-to-speech, voice cloning, and speech-to-text via an API or SDK, as well as individual creators who want to clone or generate voices through the web app.
Text-to-speech models (S1, S2-Pro, S2.1-Pro) covering 80+ languages with inline emotion and paralinguistic control, instant or persistent voice cloning from short audio samples, speech-to-text transcription, a voice-design tool that generates candidate voices from text prompts, and WebSocket-based real-time streaming, all reachable through REST/WebSocket APIs, Python and JavaScript SDKs, or the browser-based app.
Users submit text (or reference audio for cloning) to the Fish Audio API or web app; usage is billed pay-as-you-go per million UTF-8 bytes of input text for TTS and per audio hour for transcription, with no subscription fee. A voice can be cloned by uploading audio samples to train a reusable model that returns a voice ID for later text-to-speech calls, or used instantly by passing reference audio inline on a single request without training a persistent model.
