I've written a WP8 app that accepts voice commands. I've deployed and tested on the emulator and everything works fine. However, when deploying and testing on my HTC 8X the voice commands aren't detected, they don't even appear in the 'What can I say' option.
Anyone come across this before? Appreciate the help.
My guess is that the VCD CommandSet xml:lang attribute doesn't match the language and region combination used on your phone. What's the xml:lang for the CommandSets in your VCD file? And what's the language and region used by your phone?The default VoiceCommandDefinition1.xml file defaults to xml:lang="en-US", so is your phone set to the English Language in the US region?
From a development perspective, you'll have to specify a CommandSet for each xml:lang supported by your app.
Also, remember that speech recognition only works for 15-20 cultures (language+region combinations). It could be your phone is one of the unsupported locales and you won't be able to support speech recognition for that culture at all.
