Is this Swahili 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 Swahili 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 Swahili TTS and the paid Voice Synthesis service?

The free in-browser TTS uses a medium-quality Piper voice — fine for narration drafts, accessibility, and quick previews, but it sounds noticeably synthetic. The paid Subformer Voice Synthesis service uses studio-grade models (Chatterbox + Gemini TTS), 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.

Besplatni Swahili pretvarač teksta u govor

Kiswahili

Upišite ili zalijepite Swahili tekst i poslušajte ga kako se govori — sve u vašem pregledniku, bez registracije. Model glasa se preuzme jednom (~60 MB) i predmemorira lokalno, tako da su naredna pokretanja trenutačna i rade offline.

Kako to funkcioniše

1. Unesite svoj tekst
Zalijepite ili upišite bilo koji Swahili tekst — interpunkcija i prekidi redova se poštuju.
2. Generiši
Prvi klik preuzima ~60 MB model glasa u vaš preglednik. Nakon toga je sinteza trenutna.
3. Preuzmi ili pusti
Pustite audio u pregledniku ili spremite kao WAV datoteku. Audio nikada ne napušta vaš uređaj.

Vaš tekst ostaje na vašem uređaju

Sinteza se potpuno izvodi u vašem pregledniku koristeći WebAssembly. Jedini mrežni zahtjevi su za dohvaćanje Piper modela glasa i ONNX runtime-a — oba su javni, statični resursi. Ne vidimo vaš tekst i ne vidimo generirani zvuk.

Trebate glasove emiterske kvalitete?
