Have been testing voxcommando with my full home automation over the past few months. The program itself is amazing and is the perfect solution to a totally voice automated home, however it still has one major shortfall.
after I got voxcommando controlling everything (lighting, climate zones, blinds, televisions, media centers, locks and garage doors) I discovered the one biggest shortfall is the lack of a hands free always on experience.
I've extensively tested every single microphone input method you can think of including voxwav, amulet remotes, skype calls, mobiola headset etc, bluetooth headsets, and bluetooth conference call units.
for a real handsfree experience, the best route is via bluetooth headset, or something similar (like a jabra clipper). The only way to currently do this via skype call, which is not ideal.
I've recently tried the tasker and autovoice setup combined with bluetooth headset and had it triggerd by pressing a button on the headset, which is possibly close to the solution, but not quite there. Unforunately since autovoice isn't searching for the predefined phrases that vc does, it's success rate is dramatically lower (particularly with an australian accent) than if VC was handling the speech recognition.
It strikes me that the best way to achieve this is for voxwav to support bluetooth headsets, allowing a button press on the headset to trigger it start recording and complete and send the recording after a user definable timespan.
I'm not a developer so I don't really understand how complex this request is or isn't - however it would be the ideal way to control VC!
