Xport Studio vs Fish.audio
Fish.audio is a multilingual TTS platform powered by their open-source Fish Speech model · best-in-class for languages outside English. Xport Studio is a local-first music studio with voice conversion built in. They're often compared, but they do different jobs.
The short version: Fish.audio's Fish Speech model is the strongest open-source multilingual TTS available · if you're synthesizing speech in Mandarin, Japanese, Arabic, or 30+ other languages, they're the answer. Xport Studio is for music producers who need voice conversion (not just TTS), an integrated production toolkit, and the certainty that nothing leaves their machine.

Common questions
Is there a free offline alternative to Fish.audio?
Xport Studio is free to download and runs entirely on your machine. The essential tools are free forever and voice conversion is a one-time $79, with no per-generation credits.
Does Fish.audio run locally?
Fish Speech is open source and technically self-hostable, but that route means managing Python, CUDA and model weights yourself. Xport packages local inference into an installer, so you get on-device processing without assembling a stack.
Which is better for singing versus speech?
Fish.audio is strongest at text-to-speech and multilingual speech synthesis. Xport is built around singing voice conversion, taking a vocal you actually performed and converting it while preserving your timing, phrasing and delivery.
Do I need a developer background?
Not for Xport. It is a normal desktop app you install and open. Self-hosting Fish Speech assumes comfort with the command line and a working GPU setup.
Is my audio uploaded?
Not with Xport. Audio is read from disk, processed on your CPU or GPU and written back, and nothing is transmitted. Using Fish.audio's hosted service means sending audio to their infrastructure.
