The onsoundstart property of the SpeechRecognition interface represents an event handler that will run when any sound — recognisable speech or not — has been detected (when the soundstart event fires.)
mySpeechRecognition.onsoundstart = function() { ... };
recognition.onsoundstart = function() { console.log('Some sound is being received'); }
