Hi

A few years ago I used Apple's text-to-speech applying certain codes to
control the tone pitch and length of the spoken syllables making the
Mac singing instead of just speaking a text. It's something like a
string of 2 or 3 letters typed in front of each syllable.

Unfortunately I neither remember those codes nor can I find any
corresponding files in my archive. Surprisingly I can't find any
information about it online as well.

Does anybody remember or know these codes, or knows a page where I can
find more abut it?

Thanks for any help
