Syntax

rest-before: <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.
  • noneEquivalent to 0ms (no prosodic break is produced by the speech processor).
  • x-weakExpresses 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.
  • weakAs above
  • mediumAs above
  • strongAs above
  • x-strongAs above
  • inherit

Example

.class {
   rest-before: weak; 
}
