21.8. speech-rate Property

The speech-rate property is designed to allow the Web author to set the rate at which the speech is played back by the Web browser. It essentially sets the “speed” at which the text on the Web page is read.

The speech-rate property can take either a numeric value or one of a series of named values that are the equivalent of preset numeric values. All of these values are designed to set the speaking rate in terms of words read aloud over the course of a minute. Not only can this property be used to simply set the rate at which the text on the page is read, but it can also lend dramatic emphasis to text, if used properly.
