Hume AI vs Fish Audio: Features, Pricing and User Reviews 2026
What are Hume AI and Fish Audio?
Hume AI is a voice technology company that builds AI tools able to sense emotion in speech, not just the words being said. Its main product, the Empathic Voice Interface (EVI), listens closely to tone and rhythm, then replies in a voice that matches the mood of the moment.
Alongside EVI, Hume offers Octave, a text-to-speech model that turns written text into natural sounding audio across many languages, and can even clone a voice from a short clip of audio.
The company also builds tools that help other teams test and improve their own voice AI systems, using real human feedback and simulated conversations to catch problems before they reach users.
Developers connect through an API or SDK, while everyday users can try Hume's voice AI directly through its iOS app.
Fish Audio is a voice AI platform built for realistic text-to-speech, fast voice cloning, and accurate transcription. Creators, developers, and teams use it to turn text into natural sounding speech, clone a voice from a short recording, and convert speech into readable text.
The platform is powered by its own S2 and S2.1 Pro models, trained on millions of hours of audio across dozens of languages. This lets it produce speech with natural pacing, tone, and emotion, including inline tags for effects like whispering, laughing, or sighing.
Beyond text-to-speech, Fish Audio includes a voice changer, sound effect generator, audio separation tool, audio translation, and a Story Studio for combining audio into longer projects. A library of more than two million community voices is also searchable and ready to use.
Fish Audio is available as a web app for everyday use, an API for developers building apps and voice agents, and as open source models that can be self-hosted for research or production.
