Is this Japanese speech-to-text really free?

Yes. The page is public, no signup is required, and there are no length limits. The recognition model runs entirely in your browser. For higher accuracy on noisy or accented audio, run your file through Subformer's cloud transcription in Subtitles-only mode.

How does the Japanese transcription work in the browser?

It uses an open-source neural speech recognition model compiled to WebAssembly and run via ONNX Runtime Web. The model (~75 MB) is downloaded on first use and cached in your browser. Subsequent visits skip the download entirely and can transcribe offline.

Is my audio uploaded to a server?

No. Recognition runs locally in your browser. The only network calls are to download the model and the WebAssembly runtime - both are static assets. Your audio file and the generated transcript never leave your device.

What audio formats are supported?

Anything your browser can decode: MP3, WAV, M4A, AAC, FLAC, OGG/Opus, plus video containers like MP4, MOV, and WEBM (the audio track is extracted automatically).

Can I download SRT or VTT subtitles?

Yes. After transcription you can download the result as plain text (.txt), SubRip subtitles (.srt), or WebVTT (.vtt) - both subtitle formats include segment-level timestamps so you can drop them straight into any video editor or player.

Tiny vs Base - which model should I pick?

Tiny (~40 MB) is fastest and great for clean studio audio. Base (~75 MB) is roughly twice as accurate on noisy or accented audio and only slightly slower. If you're not sure, start with Base - it's the default. For the highest accuracy on hard audio (accents, noise, overlap), use Subformer's cloud transcription in Subtitles-only mode.

Does it work offline?

Once the model is cached, yes. The first visit needs network access to download it; after that the page can transcribe audio offline.

Which browsers are supported?

Any modern browser with WebAssembly: Chrome, Firefox, Safari 15+, Edge, and Chromium-based mobile browsers.

Besplatno pretvaranje govora u tekst za Japanese

日本語

Spustite Japanese audio ili video datoteku i dobijte potpuni transkript s vremenskim oznakama - sve u vašem pregledniku, bez registracije. Model se preuzima jednom (~75 MB) i kešira lokalno, tako da su naredna pokretanja trenutna i rade offline.

Provjerava se podrška preglednika…

Kako to funkcioniše

1. Spustite datoteku
Spustite bilo koji Japanese audio ili video - MP3, WAV, M4A, MP4 i WEBM su podržani.
2. Transkribuj
Prvi klik preuzme model (~75 MB) u vaš preglednik. Nakon toga, prepoznavanje je trenutno i radi offline.
3. Preuzmi
Sačuvajte transkript kao TXT, SRT ili VTT. Vaš audio i rezultat nikada ne napuštaju uređaj.

Vaš audio ostaje na vašem uređaju

Prepoznavanje se izvršava potpuno u vašem pregledniku koristeći WebAssembly. Jedini mrežni zahtjevi su za preuzimanje modela i WebAssembly runtime-a - oboje su javni, statični resursi. Ne vidimo vaš audio i ne vidimo transkript.

Treba li vam veća tačnost?

Transkripcija Japanese u kvaliteti oblaka - režim samo titlova

Besplatni alat u pregledniku koristi mali open-source model - dobar za čist audio, ali može imati poteškoća sa snažnim Japanese naglascima, šumom ili preklapanjem govornika. Za tačnost na nivou emitovanja i SRT/VTT možete direktno otvoriti video u editoru i pokrenuti datoteku kroz Subformer-ovu transkripciju u oblaku u režimu samo titlova.
