Parameters
- RateAdjust
[in] Value specifying the speaking rate of the voice. The supported values are in the range -10 to 10. Values outside this range can be truncated.

Remarks
Voices do not all have the same default rate.
The granularity of the rate is engine dependent.
Applications can adjust the rate of a voice either through this function call, or through XML passed to the voice with the input text of a speak call. The voice should combine rate adjustments made in these two ways to arrive at a final rate.
