[DECtalk] It's time to bust some DECtalk myths

[Jayson Smith]

Hi,

This definitely sounds like something is causing the synthesizer to 
reset itself, especially considering Speakup doesn't seem to know the 
settings have changed. This would result in a slight nudge of a setting 
changing it back to almost where it's supposed to be, since in most if 
not all cases, when a speech synthesizer setting is changed, the screen 
reader sends the exact value of the setting to the synthesizer, not just 
an up or down command.
