Problems as a new emacs/speechd-el user

[Cleverson Casarin Uliana]

Hi, Ive tried Emacs and speechd-el years ago, now I'm coming back to it, 
and I'd like to give it a serious try this time.

I installed Emacs 29.3 on ArchLinux, then set up speechd-el 
successfully, along with speech-dispatcher, pulseAudio and Voxin as the 
synth. the Emacs version I chose is emacs-nox, as I think I probably 
won't need any desktop stuff.

First, some Emacs keys simply don't work, namely: pageUp and pageDown, 
as well as their equivalent c-v and m-v, and also m-< and m->, neither 
of these seem to scroll the buffer. Interestingly, sometimes when I 
press page-up or c-v, speechd-el speaks beginning of the buffer, but the 
cursor is still near to the botton. Other keys work as expected, e.g. 
cn, cp, etc.

My second question is regarding the speechd-speak-signal-events 
variable. It is all filled with letters x at the respective fields, but 
speechd-el keeps speaking i.e. "empty text" instead of playing a sound 
for that event. Interestingly, when I press c-e d c to set the capitals 
mode outside of the customize group, I am able to make the capitals icon 
play.

And my last issue for now concerns speechd-voices. I am able to insert a 
new voice and give it a name, but the parameters appears as invalid or 
inactive, so I cannot set i.e. rate, volume etc.

Thanks in advance for suggestions.
