To make the spoken voice sound more interesting (and human-like), this property provides some control over the stress or inflection in the voice as it reads the text contained in the element object.
This property takes a numeric value, either integer or floating point with the value 50 being the normal default. Increasing the stress value of the voice will provide a greater variation in the way that words are enunciated. A value of zero would make the voice sound dull and unexciting.
