The CSS pitch-range property specifies the degree of variation from the average pitch of the voice being used to render the content. A voice with a small pitch range will sound monotone, while a voice with high pitch range values will sound very animated. The perceived pitch of a human voice is determined by the fundamental frequency and typically has a value of 120Hz for a male voice and 210Hz for a female voice.


Value Description
inherit Explicitly sets the value of this property to that of the parent.
<number> An integer between 0 and 100. A value of 0 produces a monotone voice, while 50 would produce a normal inflection. Pitch ranges greater than 50 create animated voices. 50 is the initial value.

HTML example:

<strong style="pitch-range:80;">OMG!</strong>

CSS example:

strong {
