About Fish Audio S
FreemiumBeginner-friendlyAPI availableWeb · API
Fish Audio S2.1 Pro is a text-to-speech and voice cloning platform offering the most expressive, emotionally controllable real-time voice model on the market. It targets creators, developers, and teams needing studio-quality voiceovers, character voices, audiobooks, and conversational chatbot voices. The platform supports fine-grained emotion control via tags like [angry], [sad], [whispering], and special effects like [laughing] or [sighing]. Voice cloning requires as little as 10–15 seconds of audio and preserves accent, tone, and speaking habits. Fish Audio also provides a 2,000,000+ voice library, multilingual support (30+ languages including Japanese, French, Arabic), and speech-to-text capabilities. The latest S2.1 Pro update delivers a free real-time TTS API for developers, while the Professional Voice Cloning service offers studio-quality verified clones. In blind tests, Fish Audio outperformed competitors like ElevenLabs in voice authenticity and emotional nuance.
Behind the Verdict
Fish Audio S2.1 Pro stands out for its free real-time TTS API and fine-grained emotion control via tags, making it ideal for content creators and developers. Its voice cloning from 15 seconds of audio is competitive with premium tools. However, the free plan has undisclosed usage limits, and the platform lacks mobile or desktop apps. It is web/API-only, which may deter users needing offline capabilities. The Professional Voice Cloning and AI Voice Design features are valuable for studio-quality results. Compared to ElevenLabs, Fish Audio offers more emotional nuance and a free tier, but advanced users may require the yearly plan for higher quotas and priority support.
