Is this Hungarian 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 Hungarian transcription work in the browser?

It uses an open-source neural speech recognition model, executed by a WebAssembly runtime on your own device. 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.

Cloud-based Hungarian Speech to Text

The free in-browser tool runs a small open-source model - fine for clean audio, but it can struggle with heavy Hungarian accents, noise, or overlapping speakers, and only covers a limited set of languages. For broadcast-grade accuracy, far broader language support, and SRT/VTT/TXT downloads, use our paid cloud-based Speech to Text.

3. Download
Save the transcript as TXT, SRT, or VTT. Your audio and the result never leave your device.

Your audio stays on your device

Recognition runs entirely in your browser using WebAssembly. The only network requests are to fetch the model and the WebAssembly runtime - both are public, static assets. We don't see your audio and we don't see the transcript.

How Hungarian transcription runs in your browser

Speech recognition normally means uploading your audio to someone's GPU. Here the model runs on your own machine instead, which is what makes this free and private at the same time.

Open-source recognition model: An open-source neural model trained on multilingual audio - which is why one download handles Hungarian with no language-specific model to fetch.
WebAssembly: The inference runtime is compiled to WebAssembly, so the numerical code runs at near-native speed inside a sandboxed tab with no plugin and no install.
On-device inference: The ~75 MB quantized model is loaded and the decoding loop is driven entirely client-side. Nothing in the pipeline calls out to a server once the page has loaded.
Web Audio API: Your file is decoded and resampled to the 16 kHz mono the model expects using the browser's own audio pipeline, so any format your browser can play is accepted.
