I don't understand what Chime means by inflection, but from the thread
so far, I'm 90% sure he doesn't mean pitch. That would leave either
freq or tone, but I'm not sure which of those that would be.

As far as I know, it is properly documented and explained in the
speakup user guide. If someone wants to use advanced methods like
synth_direct, that's fine, but that person should be prepared to deal
with the consequences of doing so.

So Chime should be able to set pitch to 113 like he wants, and be able
to save and load it with speakupconf without issues. However, Chime
said in a previous post to this thread that he set the pitch to 113,
and saved it with speakupconf. When he used speakupconf load though,
Chime said his pitch was restored to 122. My guess is there could be a
miscommunication here some where, maybe saving in /etc/speakup and
loading from $HOME/.speakup? Without seeing an exact script of a load
and restore session, and a cat of values in
/sys/accessibility/speakup/, it's difficult, if not impossible to
determine exactly what is going on.

No, do it like:

sudo echo 113 >/sys/accessibility/speakup/pitch

This will set your pitch to 113. Like I said, I think we're talking
about two different things here, pitch and inflection, whatever that means.
