Default 0

The default amount of silence defined by the speech synthesis voice.

Min 1

The minimum amount of silence defined by the speech synthesis voice.


By default, approximately 750ms of silence is appended to the end of each generated utterance. If the utterance is not a complete sentence, this can complicate concatenation of multiple utterances. For example, a streaming app that reads text from a document as it downloads, might start reading from its cache at a predetermined number of words.
