The backslash character is not allowed within a tag. An odd number of backslash characters in tagged text produce undefined behavior in the engine.
Tags are case-insensitive.
When the text to speech engine encounters a tag it does not understand, the tag is ignored. This section uses the following typographic conventions. Example Description Chr Bold type indicates speech-inflection keywords. Double square brackets indicate items that are optional. Although the Chr tag is less specific than setting the inflection, stress, attack, and whispering qualities individually, it is easier to use and allows the engine more flexibility and intelligence in its response.
