richness

The richness property allows you to specify the amount of brightness to give to the voice. You can enter a number between 0 and 100. A value of 50 is normal.

p {richness: 50}

Higher voices carry better; lower values make the voice softer. A rich voice will "carry" in a large room, a smooth voice will not. (The term "smooth" refers to how the wave form looks when drawn.)

The richness of a voice corresponds to its "bigness," its ability to carry or fill a room. Increasing values create a bigger, bolder sound; smaller values produce a quieter, gentler voice.
