The Aural Media pause-before Property
The CSS aural media pause-before property specifies a pause to be observed before speaking an element's content.
Its possible values are:
- time:It is used to specify the pause in absolute time units. The time's unit is seconds and milliseconds.
- percentage:It specifies the inverse of the value of the speech-rate property. For example, if the speech-rate is 120 words per minute (i.e. a word takes half a second, or 500ms), then a pause-before of 100% means a pause of 500 ms and a pause-before of 20% means 100ms.
