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.
