title: Change the volume of the web speech synthesizer dynamically
body: <p>Issue:</p>
  
  <p>As part of speech synthesis in web, i am using the webspeechsynthesizer and while playing the speech utterance i am trying to change the volume. I want the change to be reflected immediately on the speech utterance i.e while speaking.</p>
  
  <p>Based on my research on the web, i don't find a way to dynamically change the volume. I tried pause and resume that does not appear to work.</p>
  
  <p>Is there any possible way? </p>
  
  <p>Thanks</p>
