Definition and Usage
The ‘rest-before’ and ‘rest-after’ properties specify a prosodic boundary (silence with a specific duration) that occurs before (or after) the speech synthesis rendition of an element within the aural box model.

Syntax
rest-after : <time> | none | x-weak | weak | medium | strong | x-strong;
Values
- <time>
- Expresses the rest in absolute time units (seconds and milliseconds, e.g. “+3s”, “250ms”). Only non-negative values are allowed.
- none
- Equivalent to 0ms (no prosodic break is produced by the speech processor).
- x-weak, weak, medium, strong, and x-strong
- Expresses the rest by the strength of the prosodic break in speech output. The exact time is implementation-dependent. The values indicate monotonically non-decreasing (conceptually increasing) break strength between elements.
