Support speech inflection parameter
As requested on https://mail.gnome.org/archives/orca-list/2021-February/msg00255.html it would be useful to have a speech inflection parameter. I.e. a parameter showing up like the pitch parameter, but for the range of pitch that is used to express inflection in the voice.
This is already supported since a long time in speech-dispatcher: _client.set_pitch_range
(between -100 and 100, defaults to 0). This can very probably be implemented simply just like the pitch parameter.
