How to adjust the pace (speed)

The pace parameter controls the speed at which the speech is delivered.

It is optional — if omitted, the default value is 1.0 (normal speed).

Valid range: 0.3 (slowest) to 3.0 (fastest)
Values < 1.0 slow the speech down; values > 1.0 speed it up.
Adjust this to speed up or slow down the voice according to your needs.
