How to improve audio sound quality for Cognitive Services - Text to Speech

Question

Hi there,

I'm learning the Text to Speech service and am trying to improve the sound quality.

My code is here ...
https://gist.github.com/risingBirdSong/6568ba42f13b4eeda6deb1f09e8b38f7

the stock quality using

"X-Microsoft-OutputFormat": "riff-8khz-8bit-mono-alaw",

is poor sound quality...

however when i switch to another option (listed here)

https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/rest-text-to-speech

my audio file (mp3) won't play on and i get an error that the file is corrupt.

Do you have any suggestions for improving the sound quality? thank you :)

Please refer to this sample for converting text to speech using Node.js. Thanks.

Answer 2

In the case of Python, by using the RIFF format (stated in there), you can get better quality file.
