Nice one, bear.
But I DO wonder how your system would respond to ...
"Oh, feckin hell... now why did it do THAT?"
Not to mention that voice recognition accuracy degrades when the speaker is stressed, otherwise known as the "important demo detector".
Interestingly enough the more technical and complicated the subject the better voice recognition performs, one of the first commercially succesfull aplicatiosn was medical notes.
Of course being better than doctors handwriting is not all that difficult.
