Is this Russian text-to-speech really free?

Yes. The page is public, no signup is required, and there are no credit limits. The voice model runs entirely in your browser. For studio-grade voices and longer narration, see the paid Subformer Voice Synthesis service.

How does the Russian TTS work in the browser?

It uses Piper, an open-source neural TTS engine, compiled to WebAssembly and run via ONNX Runtime Web. The voice model (~60 MB) is downloaded on first use and cached in your browser's Origin Private File System. Subsequent visits skip the download entirely.

Is my text uploaded to a server?

No. Synthesis runs locally in your browser. The only network calls are to download the Piper voice model and the ONNX runtime - both are static assets. Your text and the generated audio never leave your device.

Does it work offline?

Once the voice model is cached, yes. The first visit needs network access to download the model; after that the page can synthesize speech offline.

What's the difference between this free Russian TTS and the paid Voice Synthesis service?

The free in-browser TTS uses a medium-quality open-source voice - fine for narration drafts, accessibility, and quick previews, but it sounds noticeably synthetic. The paid Subformer Voice Synthesis service uses studio-grade neural models, supports voice cloning, and produces broadcast-quality audio. Visit /dashboard/voice-synthesis to try it.

Which browsers are supported?

Any modern browser with WebAssembly: Chrome, Firefox, Safari 15+, Edge, and Chromium-based mobile browsers. The page runs ORT in single-threaded mode so it works in every common browser without requiring cross-origin isolation.

Can I download the audio?

Yes. After synthesis you can play the audio inline or click Download to save it as a 22 kHz mono WAV file. Use any audio editor to convert to MP3 or other formats.

Bure Russian Kutoka Maandishi hadi Sauti

Русский

Andika au bandika maandishi ya Russian na usikie yakiongelewa - yote ndani ya kivinjari chako, bila kujiandikisha. Mfano wa sauti unapakuliwa mara moja (~60 MB) na umehifadhiwa kwenye kifaa chako, kwa hivyo mara za baadaye ni papo hapo na hufanya kazi bila mtandao.

Inavyofanya kazi

1. Andika maandishi yako
Bandika au andika maandishi yoyote ya Russian - alama za uakifishaji na mapumziko ya mistari zinazingatiwa.
2. Tengeneza
Bonyeza mara ya kwanza kunapakua takriban ~60 MB ya modeli ya sauti kwenye kivinjari chako. Baada ya hapo, uundaji wa sauti ni wa papo kwa hapo.
3. Pakua au sikiliza
Cheza sauti ndani ya ukurasa au uiwekee kama faili ya WAV. Sauti haiendi nje ya kifaa chako.

Maandishi yako yanabaki kwenye kifaa chako

Uundaji unafanyika kabisa ndani ya kivinjari chako kwa kutumia WebAssembly. Maombi pekee ya mtandao ni ya kupakua modeli ya sauti ya Piper na runtime ya ONNX - zote ni rasilimali za umma, statiki. Hatuoni maandishi yako na hatuoni sauti iliyotengenezwa.
