title: how to get word timestamp in nemo ASR( speech to text)
body: <p>I am following Nemo nvidia doc and trying to convert speech to text. My code is below:</p>
  <pre><code>import nemo.collections.asr as nemo_asr
  
  
  
  quartznet = nemo_asr.models.EncDecCTCModel.from_pretrained(model_name=&quot;QuartzNet15x5Base-En&quot;)
  
  
  
  Audia_sample = &quot;./some_file.wav&quot;
  
  
  
  files = [Audio_sample]
  
  
  
  raw_text = ''
  
  
  
  for fname, transcription in zip(files, quartznet.transcribe(paths2audio_files=files)):
          raw_text = transcription
  </code></pre>
  <h1>raw_text is giving me plain text. But my requirement is that it will give output with time also.</h1>
  <p>Output :</p>
  <p>well i don't wish to see it any more observed phoebe turning away her eyes it is certainly very like the old portrait</p>
  <p>expected output:</p>
  <p>[{'segment': 'well i don't wish to see it any more observed phoebe turning away her eyes', 'start': 5.11, 'end': 8.52}, {'segment': 'it is certainly very like the old portrait', 'start': 8.77, 'end': 12.12}]</p>
