Web Speech API - Speak again (reset sentence)

Question

i use the webkitSpeechRecognition() to create my own little voice recorder.

Here is a demo (works only with chrome!)
http://jsfiddle.net/gsu4aod2/

Say a sentence and
1a.) if the text correct, click on the "add sentence" button
1b.) if the text not correct click the "speak again" button

My problem is that i dont know how to "reset" the text. When i use the stop() and start() method, the text is removed but than i must confirm the access to the microphone again and again.

Any ideas?

Answer 1

You are getting the events.result data starting from index 0. You need to start the for loop with something called event.resultIndex.

resultIndex attribute: The resultIndex must be set to the lowest index in the "results" array that has changed. [source]

recognition.onresult = function (event) {
    //console.log(event);
      var final = "";
      var interim = "";
      for (var i = event.resultIndex; i < event.results.length; ++i) {
        if (event.results[i].final) {
          final += event.results[i][0].transcript;
        } else {
          interim += event.results[i][0].transcript;
        }
      }
