Is this Slovak 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 Slovak 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 Slovak 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.

Libreng Slovak Text to Speech

Slovenčina

Mag-type o i-paste ang Slovak na teksto at pakinggan itong binibigkas - lahat sa iyong browser, walang signup. Ang modelo ng boses ay mada-download nang isang beses (~60 MB) at naka-cache nang lokal, kaya ang mga susunod na pagtakbo ay instant at gumagana offline.

Paano ito gumagana

1. I-type ang iyong teksto
I-paste o i-type ang anumang Slovak na teksto - iginagalang ang mga bantas at mga paghiwalay ng linya.
2. Mag-generate
Sa unang pag-click, idi-download ang ~60 MB na voice model sa iyong browser. Pagkatapos nito, instant ang sintesis.
3. I-download o i-play
Patugtugin ang audio nang inline o i-save ito bilang isang WAV file. Hindi umaalis ang audio sa iyong device.

Mananatili ang iyong teksto sa iyong aparato

Ang pagsintesis ay tumatakbo nang buo sa iyong browser gamit ang WebAssembly. Ang tanging mga network request ay para kuhanin ang Piper voice model at ang ONNX runtime - pareho silang pampublikong static na asset. Hindi namin nakikita ang iyong teksto at hindi rin namin nakikita ang nabuo na audio.

Kailangan mo ba ng mga boses na broadcast-quality?
