title: Change voice in android
body: <p>I am using media recorder to record the voice but I want to play the voice in female tone or vice versa.
  Basically i have a media player sound and when I play it, it runs fine but now I have recorded my voice using media recorder and I want to play it female tone?
  How can I change the male voice to female voice or female voice to male voice?
  I have also tried to use soundpool class but it increases or decreases the frequency. It does not change the tone or pitch of voice.</p>
