+<p>The <code><strong>result</strong></code> event of the <a href="/en-US/docs/Web/API/Web_Speech_API">Web Speech API</a> is fired when the speech recognition service returns a result — a word or phrase has been positively recognized and this has been communicated back to the app</p>

+
+<p>Or use the <code><a href="/en-US/docs/Web/API/SpeechRecognition/onresult">onresult</a></code> event handler property:</p>
