a numerical value representing the degree of match. The expected
language format is a string similar to the following, where the
delimiter can be '-' '_' or '.':
de-DE (German for Germany)
en-US (English as used in the United States)
Additional extensions for variants or dialects are allowed as well.
The return value is one of the following:
0 - no match at all
1 - some match

Z RS( sW Implements gnome-speech's SpeechCallback class. The gnome-speech
server only allows one speech callback to be registered with a speaker
and there's no way to unregister it. So...we need to handle stuff
like that on our own. This class handles this for us and also delegates
all calls to the 'real' gnome speech speaker.

the punctuation. We try to detect this by looking for just a
single character being spoken.
