Browser Speech Recognition: The Web Speech API You're Not Using

The Web Speech API has been in Chrome since 2013. It provides real-time speech-to-text directly in the browser, with no external service, no API key, and no server upload. And almost nobody uses it for anything beyond voice search demos. The API const recognition = new ( window . SpeechRecognition || window . webkitSpeechRecognition )(); recognition . continuous = true ; recognition . interimResults = true ; recognition . lang = ' en-US ' ; recognition . onresult = ( event ) => { let transcript = '' ; for ( let i = event . resultIndex ; i < event . results . length ; i ++ ) { transcript += event . results [ i ][ 0 ]. transcript ; } document . getElementById ( ' output ' ). textContent = transcript ; }; recognition . start (); That's a working speech-to-text implementation in 15 lines. continuous: true keeps listening after pauses. interimResults: true shows text as you speak, not just after you finish. What it can and can't do Accuracy : Good for clear speech in a quiet environment. Na
