Listen/Record speechRecognition audio

Question

I built a simple application using speechRecognition

startListening() {
  let options = {
    language: 'en-US'
  }
  this.speechRecognition.startListening().subscribe(matches => {
    this.matches = matches;
    this.cd.detectChanges();
  });
  this.isRecording = true;
}

I wonder if I can use a recorded audio to perform speechRecognition or if there is a possibility to save the audio that was used.
