Speech to Text

Speak into your mic and watch your words appear as text. Uses the browser Speech Recognition API. Best in Chrome.

How to use Speech to Text

  1. Pick the language and accent you will speak in from the dropdown — this strongly affects accuracy.
  2. Click "Start" and allow microphone access when your browser prompts you.
  3. Speak naturally and clearly. Words appear in the transcript box as the recognizer finalises each phrase.
  4. Click "Stop" when you are finished, then edit the transcript directly to fix any misheard words or add punctuation.
  5. Use the copy button to grab the finished text and paste it wherever you need it.

Turning speech into editable text in your browser

This tool listens to your microphone and writes down what you say in real time, so you can dictate notes, draft an email, or capture ideas without typing. It uses a capability built into the browser itself — there is nothing to install — and the transcript appears live as you talk, ready to edit.

How browser speech recognition works

The tool uses the Web Speech Recognition API (SpeechRecognition, and its webkit prefixed form). When you start, the browser opens your microphone and streams the audio to its speech service, which returns a stream of guesses. As each phrase is finalised, it is appended to the transcript. Setting continuous mode keeps it listening across pauses, and interim results let words appear while you are still speaking.

Browser support — be aware it varies

This is one of the less universally supported web APIs. Chrome and Edge (and other Chromium browsers like Opera and Brave) give the best results. Safari supports it on recent macOS and iOS. Firefox does not support it at all, so the tool will show a fallback message there. If transcription is not working, switching to Chrome is usually the fix.

A note on privacy

Most SnapTools media tools run completely on-device, but speech recognition is different: the browser sends your audio to its vendor's servers (Google for Chrome, Apple for Safari) to do the heavy lifting, then returns text. SnapTools itself never sees or stores your audio or transcript — but because the browser maker processes the speech in the cloud, you should avoid dictating passwords, financial details, or other highly sensitive information.

Getting the most accurate transcript

  • Match the language and accent. Choosing English (UK) versus English (US), or the right Spanish variant, noticeably improves recognition.
  • Reduce background noise. A quiet room and a close, decent microphone help enormously.
  • Speak in natural phrases. Steady, clear sentences transcribe better than rushed or mumbled speech.
  • Edit afterward. The transcript box is fully editable — fix proper nouns and add punctuation before copying.

  • Audio Recorder — keep a fully on-device copy of the audio alongside the cloud-made transcript.
  • Text to Speech — the opposite direction, and one that stays local when you use installed voices.
  • Screen Recorder — narrate a walkthrough out loud while capturing the screen.

Frequently asked questions

Which browsers support live transcription?
The Web Speech Recognition API is best supported in Chromium-based browsers — Chrome, Edge, Opera, and Brave — where it is the most accurate and stable. Safari on macOS and iOS also supports it. Firefox does not implement speech recognition, so this tool will not work there.
Does the audio stay on my device?
Not entirely. Unlike most of our media tools, browser speech recognition sends your microphone audio to the browser vendor's cloud service for processing — Google's servers in Chrome, Apple's in Safari. SnapTools never receives or stores anything, but the speech itself is processed by the browser maker, so avoid dictating highly sensitive information.
Why is the transcription inaccurate or missing words?
Accuracy depends heavily on choosing the right language/accent, a quiet environment, and a good microphone. Speak at a natural pace, avoid heavy background noise, and pick the dialect closest to your accent (for example, English UK vs English US). Technical terms and proper nouns are the most error-prone — fix those by editing the transcript.
Can I add punctuation by voice?
Support varies by browser and language. In many cases you can say "comma", "period", or "new line" and the recognizer inserts the symbol, but it is inconsistent. The reliable approach is to dictate the words and then add punctuation yourself in the editable transcript box.
Does it work offline?
No. Because the recognizer relies on a cloud service, you need an internet connection. If the connection drops you may see a network error; reconnect and click Start again.
Why did my microphone get blocked?
A denied permission stops recognition before it starts. Click the microphone icon by the address bar, allow it again, and refresh. The Web Speech Recognition API also expects an HTTPS page (this one qualifies) and a microphone the browser can actually open.
Can I transcribe an existing audio file?
This tool transcribes live speech from your microphone, not uploaded files. To transcribe a recording, play it aloud near your microphone while the recognizer listens, or use a dedicated file-transcription service.
How long can a single session run?
The recognizer runs continuously while you record, but browsers may auto-stop after a long pause or extended silence. If it stops unexpectedly, just click Start again — your existing transcript is kept and new text is appended.
