Patch for DECTalk Express driver

[Trevor Astrope]

Fwiw, my preference is to set pitch to 75  and rate to 8.

It was set at 200 which was way too high.  I've lowered it to 150.  It's still raised but it isn't very high like it was.  Finally, I added a space before the closing "]" when sending commands to the synthesizer.  That was recommended by the manual.  Also, I disabled the volume adjustment.  According to the manual, it does not have a way to adjust the volume with software.  On my unit, setting the volume to 14 causes static and overloads the internal filters.  The "gv" parameter doesn't actually change the volume, it changes a characteristic of the voice.
