It is available on the web. 8 of 9 checklist rows are verified against a public source. Source: https://altcatalog.com/alternatives/fish-audio/ Category: AI voice generation ## Overview - **Who it's for**: 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. - **What you get**: 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. - **How it works**: 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. ## Profile - **Pricing model**: Usage-based (verified 2026-07-30) - **Starts at**: $15/M UTF-8 bytes (TTS) (verified 2026-07-30) - **Platforms**: Web - **Status**: active (verified 2026-07-30) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [Cartesia](https://altcatalog.com/alternatives/cartesia.md) | 100 | Proprietary | ? | | 2 | [Speechify](https://altcatalog.com/alternatives/speechify.md) | 100 | Proprietary | iOS, Android, macOS, Windows | | 3 | [Camb.ai](https://altcatalog.com/alternatives/camb-ai.md) | 95 | Proprietary | Web | | 4 | [ElevenLabs](https://altcatalog.com/alternatives/elevenlabs.md) | 95 | Proprietary | Web, iOS, Android | | 5 | [Murf](https://altcatalog.com/alternatives/murf.md) | 95 | Proprietary | Web | | 6 | [Resemble AI](https://altcatalog.com/alternatives/resemble-ai.md) | 90 | MIT | Web, Browser extension | | 7 | [Hume AI](https://altcatalog.com/alternatives/hume-ai.md) | 85 | Proprietary | Web | | 8 | [WellSaid](https://altcatalog.com/alternatives/wellsaid.md) | 85 | Proprietary | Web | | 9 | [Lovo (Genny)](https://altcatalog.com/alternatives/lovo.md) | 80 | ? | Web | Alt Score = Verified coverage (90%) + Visibility (10%).
