Microsoft speaker identification

Something that I'd like to add to the Grace application is speaker identification. There are two benefits:

1.	If you can identify the speaker, you can switch to their recognition profile which improves the accuracy.

2.	The speaker can use words like "I" and "me". ex. "I have an appointment tomorrow at 3:00 PM".

Until I get something like this working, it would be impossible for Meredith to make use of a kitchen setup, since the recognition accuracy for her voice against my recognition profile would be unusable.

I came upon an interesting page at Microsoft today: http://research.microsoft.com/en-us/projects/whisperid/default.aspx. It's neat to see that they're working on some of the same things.
