title: Python gTTS, is there a way to change the speed of the speech
body: <p>It seems that on gTTS there is no option for changing the speech of the text-to-speech apart from the slow argument. </p>
  
  <p>I would like to speed up the sound by 5%. Any suggestion on how I can do it? </p>
  
  <p>Best.</p>
  
  <pre><code>tts_de = gTTS("Hallo, guten tag.", lang = 'de')
  tts_de.save("s.mp3")
  </code></pre>
