Make Mac OS X acknowledge Speech Recognition keyword?

Can I make Mac OS X "ping" when it recognizes the Speech Recognition keyword?

It pings when it recognizes a phrase, but that's a little different.

My speech recognition is working fine without a开发者_如何学编程 keyword, but fails when I use a keyword, even if it's a short keyword like "Bob" or "Hal".

If I can at least know when it's accepted the keyword, it would be helpful.

Have other people tried to use Speech Recognition on your machine and failed? The recognizer can, sometimes, have issues with certain accents. Use the OS X text-to-speech system to read out what you want to say (use Alex or one of the other normal-speech voices [i.e. not Zarvox]) and try to match its pronunciation exactly.
