Speech pitch

I’m running OSX 10.3.3. I don’t know when things changed, but I’m no-longer able to change the pitch of my Macs voices.
[[inpt PHON]], [[rate ##]], and a few others still work, but
[[pmod]] &[[pbas]] have no effect at all anymore.
Is there some new way to change pitch for a A.S.S. project?
Thanks in advance to anyone who can help me with this.
