Speech to text
Speech to text, online and free
Dictate in your browser and watch your speech become text, in 12 languages — transcribed by an AI model running on your own device, with nothing uploaded. Copy the result anywhere. It's a live preview of what voice typing feels like.
Press Start dictation, allow the microphone, and speak. The first run downloads a small speech model to your browser, then your words appear here — all on your device.
Runs an OpenAI Whisper model entirely in your browser — your audio never leaves your device, and after the first download it works offline. For dictation that types polished writing into any Mac app, use Openbroca.
Turn your voice into text, privately
Press start, allow the microphone, and speak naturally — your words are transcribed as you talk and refreshed every couple of seconds. The first time, a small speech model downloads to your browser; after that it's cached and even works offline, and your audio never leaves your device. Pick from a dozen languages, keep dictating across pauses, and copy the finished text into an email, document, or message. It's a fast way to draft hands-free — or just to see how good in-browser speech recognition has become.
Browser speech-to-text vs Openbroca
This tool runs an open-source Whispermodel locally in your browser — your audio never leaves your device. That's great for a private, quick demo, but it has real limits:
- It only types into this page — not into your editor, chat, or terminal.
- The first run downloads a model, and transcription speed depends on your hardware — it's fastest on devices with WebGPU.
- To stay lightweight it uses a small model, so it won't match a full cloud model on tricky audio, names, or accents.
Openbroca takes voice typing system-wide on your Mac: speak, and your words become polished writinginserted wherever your cursor is — editors, browsers, chat, the terminal — with a copy fallback when an app won't take direct insertion, and talk-to-translate into 28 languages along the way. It's a native macOS app, so it isn't limited to one browser tab. Learn what Openbroca does or see how it compares to Apple Dictation.
Tips for better accuracy
- Use a decent microphone in a quiet room.
- Speak at a steady, natural pace — no need to over-enunciate.
- Pick the language that matches your speech.
- Whisper adds punctuation and capitalisation for you — just talk normally.
- On the first run, give the model a moment to download; it's cached for next time.
Frequently asked questions
Is this speech-to-text free?
Yes. It's free, requires no account, and has no usage limits — it runs an open-source Whisper model right in your browser.
Does it work offline?
Yes, after the first load. The initial run downloads the speech model to your browser and caches it, so later sessions work with no connection — and your audio never leaves your device. Openbroca is a native, cloud-powered Mac app that turns your speech into polished writing wherever your cursor is.
Why doesn't it work in my browser?
This tool needs a browser that can record audio (MediaRecorder) and run WebAssembly — the latest Chrome, Edge, Safari, and Firefox all qualify, and a device with WebGPU will be noticeably faster. Or get Openbroca for native dictation that types into any app on your Mac.
What languages are supported?
This demo offers 12 common languages including English, Spanish, French, German, Chinese, Japanese, and more. Openbroca also does talk-to-translate into 28 languages, turning what you say into polished writing in another language.
Can I dictate into other apps with this?
No — the browser tool only types into this page. Openbroca delivers polished writing into whatever app is focused, system-wide on your Mac.
