title: Speech recognition with precise timestamp?
body: <p>Hy Community,</p>
  
  <p>i´ve worked with Google´s txt to speech API.</p>
  
  <p>When i would like to encode an wav audio file (extracted from an video), the timestamps for some words are not very precise. (the resolution according google is 0,1sec - but in my case, sometimes its more weak/delay).</p>
  
  <p>I thought i could try a workaround by decrease the speed of audio file, but it´s more or less the same result. </p>
  
  <p>Somebody know some precise API´s for speech recognition, or have some hints for better preparing the audio files?</p>
  
  <p>i would like to determine one by one word including theire exact timestamps.</p>
  
  <p>Thanks a lot!</p>
