About

Fish Audio is a professional-grade AI audio platform built for creators, developers, and businesses who need expressive, natural-sounding voice generation. Powered by its proprietary Fish Audio S1 and S2 Pro models, the platform offers three core capabilities: Text-to-Speech (TTS), Voice Cloning, and Speech-to-Text transcription. With TTS, users can generate studio-quality narration with fine-grained emotion tags—switching tones mid-script to match video scenes, audiobook chapters, or chatbot personalities. The Voice Cloning feature requires as little as 15 seconds of source audio to produce a highly accurate voice replica, making it ideal for brand personas, game characters, and personalized content. Fish Audio's Voice Library hosts 2M+ community and pre-built voices available for immediate use. The platform is purpose-built for diverse use cases: YouTube and ad voiceovers, ACX/Audible-compliant audiobook narration, animated character voices, and low-latency conversational AI agents. An API is available for developers to integrate TTS and cloning into applications, chatbots, and real-time avatar systems. Fish Audio supports multilingual output with native-level quality across 8 languages, including Japanese, French, and Arabic. A free tier allows users to get started immediately, while pro plans unlock higher usage limits and advanced features. It has earned strong reviews from content creators who cite its emotional nuance and voice authenticity as superior to competing platforms.
