I have built a text to speech system that is generating speech for a given text, however the generated audio has a lot of vibrations in it. Although the speech is clear, it doesn't really sounds natural and is a bit robotic.

Here is a sample of the generated audio: Audio

Please give some suggestion on how I can clean this audio and make it sound more natural.

It seems like your sample rate is very low. That is handy for keeping sizes low, but it ruins the output (unless you like robot speech)

Try higher quality samples and a much higher sample rate.

  • The sample rate is at 22khz. Is there a way I can modify this audio to make it more natural sounding? – Chris Andrew Jan 14 at 23:47
  • Weird. It sounds much lower. I'd have guessed half that from your audio clip – Rory Alsop♦ Jan 15 at 13:27
  • The audio is computer generated, so that might be why it seems the sample rate is low. – Chris Andrew Feb 26 at 12:51
