CSS pitch property

This property specifies the average pitch (a frequency) of the speaking voice. The average pitch of a voice depends on the voice family. For example, the average pitch for a standard male voice is around 120Hz, but for a female voice, it's around 210Hz.

The possible values are −

• frequency - Specifies the average pitch of the speaking voice in hertz (Hz).
• x-low, low, medium, high, x-high - These values do not map to absolute frequencies since these values depend on the voice family.
