It combines text-to-speech, voice cloning and speech-to-text with emotional control, so you can tag a line as [whispering], [excited] or [sobbing] and get delivery that matches the script rather than flat narration. The voice library is enormous, with community-uploaded voices numbering in the millions across a wide range of languages. Cloning is fast and forgiving: a short sample is enough to build a usable voice model, and it can then speak in many languages while keeping the original timbre. Fish Audio publishes powerful APIs for real-time streaming, cloning and transcription, and positions itself for enterprise work such as conversational agents, dubbing and audiobook production. The company also keeps an open-source arm, releasing the Fish Speech model line for self-hosting, while the hosted platform adds a browser studio, avatar and image/video model integrations, and paid tiers for higher volume. Free starting tiers make it easy to evaluate before committing. **Pricing & Plans:** Freemium: free sign-up with monthly generations, plus paid subscriptions for higher volume, commercial use and API access; enterprise pricing on request. - **Expressive Text to Speech:** Type or paste a script and generate natural narration, with inline emotion and delivery tags such as [whispering], [angry] or [laughing]. - **Instant Voice Cloning:** Create a usable voice clone from a short audio sample and reuse it across scripts and languages. - **Huge Voice Library:** Browse and use a large catalog of community voices covering many languages and character styles. - **Speech to Text:** Transcribe audio with multilingual support and emotion or speaker cues for downstream editing. - **Real-time Voice APIs:** Low-latency streaming endpoints let developers build conversational agents, dubbing pipelines and audio apps. **Strengths:** Natural, emotionally controllable output that handles nuance well; Voice cloning works from a very short sample; Very large shared voice library plus open-source model lineage; Robust APIs for real-time streaming and developer integration **Limitations:** Free tier is limited and top-quality usage pushes you toward paid plans; Voice cloning raises consent and impersonation risks that teams must manage; Some features and model names change quickly, so docs can lag the product [Profile (Markdown)](https://openaitools.app/tool/fish-speech.md) ## Thinkstack.ai Thinkstack.ai lets you build a working AI chatbot in minutes without writing code. You feed it your knowledge sources — help docs, websites, FAQs, internal content — and it answers customer questions in your brand voice. On top of simple Q&A, it supports agentic behavior: chatbots that take actions, follow multi-step workflows, and operate with minimal human oversight. Beyond answering questions, Thinkstack covers the full support and sales loop.
