The Microsoft Agent services support modifying speech output through special tags inserted in the speech text string. These tags help you change the characteristics of the output expression of the character. The single backslash character is not enabled within a tag.
Tags are case-insensitive.
Speech output is automatically reset through the user-defined parameters after a Say method is completed. Some tags include quoted strings. This means that you have to use two quote marks to designate the tag's parameter or concatenate a double-quote character as part of the string. Only the Mrk and Map tags can be used with sound file-based spoken output. Parameters may also vary depending on the TTS engine installed.
