Fish Audio
Fish Audio provides text-to-speech, voice cloning, speech-to-text, voice agents, and other audio tools. Its text-to-speech controls cover emotion and expression, real-time generation, multilingual output, speed, volume, and model parameters. Fish Audio says TTS supports eight languages with native accents and its platform hosts more than 2,000,000 voices. Developers can use the API for speech generation, voice cloning, and transcription through REST, WebSocket streaming, and official Python and TypeScript SDKs. The listed platforms include web, Linux, macOS, Windows, API access, and self-hosting. Use cases named by the company include video voiceovers, audiobook narration, character voices, and conversational chatbots. The Free Tier costs nothing and allows 8,000 monthly credits, up to 7 minutes of generation, and personal, non-commercial use. Plus costs $11 a month, billed $132 billed annually; paid plans are listed from $15/mo. Commercial use is listed as available. Enterprise deployments include VPC, on-premises, air-gapped, and sovereign cloud options.
