Speech to Text
Turn on the microphone and talk. Your browser's own speech recognition writes down what it hears, so you can see how it copes with different languages and accents.

Nothing yet. What you say shows up here, newest at the bottom.
Grey text is the recogniser's guess while you are still talking; it settles into a line when it's sure. Each line shows its confidence where the browser reports one, and the other guesses it considered. Chrome and Edge send the audio to Google's or Microsoft's speech service; Safari may recognise on the device. Firefox has no speech recognition.
