You can use Speech Tags wherever you can specify text to be spoken using Text to Speech (TTS). Speech Tags can be used to change the quality of the voice itself, or to change the pronunciation of a word. Some tags, such as [silence 1s] are used alone, but most are opening and closing tags that form a pair that wrap a word or phrase, such as [digits]123[/digits].
You can use the Script panel's Play button to listen to your tagged text to make sure it sounds right. If you hear the voice speak the text of a tag, then you know that the tag was not understood as a tag - check the spelling using the reference below. Be sure that each opening tag has a corresponding closing tag. If tags are not properly matched, you may not hear the voice at all.
Here is a list of available tags.
