Thanks @ yutongtie-msft , Your answer helped lot.

There are two ways to change the speed rate for Text to Speech.

1. Create a custom voice. Refer here

2. SSML language: use the SSML language to control the speaking speed. You can change to use SSML as input to call speech service. Then it can change the speech rate.

   The prosody element is used to specify changes to pitch, contour, range, rate, duration, and volume for the Text-to-Speech output.

< prosody pitch="value" contour="value" range="value" rate="value" duration="value" volume="value"> < /prosody>

Rate Indicates the speaking rate of the text. You can express rate as:

A relative value, expressed as a number that acts as a multiplier of the default. For example, a value of 1 results in no change in the rate. A value of 0.5 results in a halving of the rate. A value of 3 results in a tripling of the rate.

A constant value:

• x-slow

• List item

• slow

• medium

• fast

• x-fast

• default
