staging/speakup: Add inflection synth parameter
Browse files Browse the repository at this point in the history 
The inflection parameter, i.e. the pitch range, allows to change the
expressiveness of the synthesized voice.  This is supported by the DEC
talk synths, and software synthesizers such as espeak/espeak-ng.
