The Vista Show is a podcast that broadcasts a weekly show in podcast format each week from thevistashow.com. This week Jack discusses Vista's Windows Speech Recognition. You can jump ahead to the 18 minute mark in the MP3 file.
Jack says Windows Speech Recognition has come a "long way. A long long way..." His daughter (who is eleven) was excited to use it. He says, "That will be her future... Our future of computers will be no more keyboards..."
That's pretty similar to my experience with my son, Zac. He recently used WSR to do about 50% of a report for school. It's that easy to use. He's 9 years old!
Jack closed his podcast with saying, "It's very user friendly!"
If you haven't tried it out, go buy Vista and give it a shot.
