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

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

Provjerava se podrška preglednika…

Kako to radi

1. Povucite datoteku
Ubacite bilo koji Japanese audio ili video - podržani su MP3, WAV, M4A, MP4 i WEBM.
2. Transkribiraj
Prvim klikom model od ~75 MB se preuzima u vaš preglednik. Nakon toga je prepoznavanje trenutačno i može raditi bez interneta.
3. Preuzmi
Spremite transkript kao TXT, SRT ili VTT. Vaš audio i rezultat nikada ne napuštaju vaš uređaj.

Vaš audio ostaje na vašem uređaju

Prepoznavanje se izvršava u potpunosti u vašem pregledniku koristeći WebAssembly. Jedini mrežni zahtjevi su za dohvat modela i WebAssembly runtimea - oba su javni, statični resursi. Ne vidimo vaš audio i ne vidimo transkript.

Trebate veću točnost?

Transkripcija Japanese u kvaliteti oblaka - samo način za titlove

Besplatni alat u pregledniku pokreće mali model otvorenog koda - dovoljan za čist audio, ali može imati poteškoća s jakim Japanese naglascima, šumom ili preklapanjem govornika. Za televizijsku razinu točnosti i SRT/VTT možete datoteku izravno ubaciti u video editor i pokrenuti je kroz Subformerovu transkripciju u oblaku u načinu Samo titlovi.
