CSS voice-pitch Property


The voice-pitch 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 voice-pitch property has been deprecated or is no longer in any CSS working groups.

Initial value
Applies to
All elements
Computed value
One of the predefined pitch keywords if only the keyword is specified by itself, otherwise an absolute frequency calculated by converting the keyword value (if any) to a fixed frequency based on the current voice-family and by applying the specified relative offset (if any)
JavaScript syntax


voice-pitch: <frequency> && absolute | [[x-low | low | medium | high | x-high] || [<frequency> | <semitones> | <percentage>]]


  • <frequency>A value in frequency units (Hertz or kiloHertz, e.g. "100Hz", "+2kHz"). Values are restricted to positive numbers when the 'absolute' keyword is specified.
  • absoluteIf specified, this keyword indicates that the specified frequency represents an absolute value. If a negative frequency is specified, the computed frequency will be zero.
  • <semitones>Specifies a relative change (decrement or increment) to the inherited value. The syntax of allowed values is a followed immediately by "st" (semitones).
  • <percentage>Positive and negative percentage values are allowed, to represent an increment or decrement (respectively) relative to the inherited value.
  • x-lowA sequence of monotonically non-decreasing pitch levels that are implementation and voice specific. When the computed value for a given element is only a keyword (i.e. no relative offset is specified), then the corresponding absolute frequency will be re-evaluated on a voice change.
