How many languages does the Text to Speech generator support?

The OmniVoice TTS generator supports 646 languages — the broadest coverage of any free TTS tool. This includes English, Mandarin, Spanish, Arabic, Swahili, Welsh, Tok Pisin, and hundreds more.

What's the difference between Text to Speech, Voice Cloning, and Voice Design?

Text to Speech generates natural speech from text using an automatically selected voice. Voice Cloning replicates a specific speaker from a 3–25 second audio sample you upload. Voice Design creates a custom voice from a text description — no audio required.

How long can my input text be?

The online generator supports up to 500 characters per generation. For longer documents, OmniVoice TTS can be self-hosted via the open-source release with no character limits.

What audio format does the generator output?

Generated audio is delivered as a .wav file, playable in any browser or audio app. You can download it immediately after generation — no account needed.

Can I use the generated audio commercially?

Yes. OmniVoice TTS is licensed under Apache 2.0, which explicitly permits commercial use of both the model and its output. It was also trained exclusively on open-source data, so there are no hidden licensing restrictions.

How accurate is the Text to Speech output?

In a 24-language benchmark, OmniVoice TTS achieved 2.85% word error rate — versus 10.95% for ElevenLabs. Across most languages, the output is accurate enough for professional use without manual correction. (Source: arXiv 2604.00688)

Does Voice Cloning work across languages?

Yes. Upload an English reference clip, and OmniVoice TTS can generate speech in Mandarin, French, Arabic, or any of 646 other languages using the same cloned voice. No additional samples needed per language.
