I downloaded a new voice dialer yesterday that I think is pretty cool. It is called Melodis Dialer. It's pretty much the same thing as Say Who and just as accurate. However, I think it works about twice as fast. Check it out - it may replace your Say Who if you have it. Another voice activated app I downloaded today was vLingo. This appears to be very similar to the voice search in Google Mobile App, but instead of just finding your contact, you can call it too. Plus, unlike Google Mobile App, you can make a post on your Social Networking page, like Facebook, with just your voice. I have not tried this function yet, so I don't know if it works. You can also directly search on Google Maps. Things developed outside of Apple are progressing well. Pretty cool!
