Hey Pegleg:
FYI on remapping Push To Talk (PPT) for voice from Mobile Tech Review
The phone offers voice commands and voice dialing though this isn't true speech recognition; you'll need to record voice tags. The software is Cyberon's Voice Speed Dial which we like nonetheless and it's made prior appearances on E-TEN and ASUS Pocket PC phones as well as the Cingular 8125. The software is very good at recognizing recorded voice tags, doesn't make dangerous guesses like certain otherwise beloved Nokia S60 3rd Edition smartphones (our
Nokia N80 and E70 have a nasty habit of picking and dialing international contacts from our address books when they couldn't understand us). It also works with Bluetooth headsets and car kits, unlike
Microsoft Voice Command which does true speech recognition. On the TyTn, you need only press the voice speed dial button on the phone's left side to initiate voice dialing and commands. Sadly, the Cingular 8525 re-purposes this button as the Push to Talk button; a feature that isn't even yet implemented on the 8525. That button isn't remappable using the Buttons settings applet, but Sleuth255 on
XDA Developer's web site has developed a small app that allows you to re-map it to the voice dialer (or another application if you prefer)
