The pitch range allows for the voice to raise and fall during speech to make it sound more interesting.
The value of 0 can be used to prevent any pitch change during speech. This would cause speech to use a monotone and sound very dull. A value of 50 would sound normal while a value of 100 would sound somewhat excited.
