Those of you with either a fast connection or a lot of time ;) can download a new program called Tazti (pronounced Tasty...like ice cream).
It works like a vocal environment where one can control the computer via spoken voice to search, play, browse music files, stocks, etc.
I thought it was worth a look and possibly might have the ability to interface with other programs like chatbots, etc.
If nothing else, it should be fun to try.

From the demo film that looks very good. Hal can/could do a lot of that too. I'll have to wait until I get my headset though. I'm guessing it might be based on MS speech rocognition but couldn't find any info about it.
