Mark has a low end Android phone running Marshmallow. Ever since the last update, any time he uses the voice command feature, he's noticed a message that says it's sending audio to his Gmail account. Leo says it's a normal function of Google voice command. It's just letting him know what account that service is associated with. It's not emailing him, it's just letting him know what account it's using. The phone isn't really doing the dictation, it's sending the voice data to Google servers. It looks like Google is being transparent about it.
Joe has a Harmon Kardon Bluetooth speaker and he is having trouble playing music from his phone. It pairs with it, but he can't figure out how to give it the command to play music. Leo says that he has the Harmon Kardon Invoke and it sounds great for $100, but it may not be made "aware." He'll have to go into his phone's Bluetooth settings. On the Amazon Echo, you have to tell it to connect to the phone and then pair it in the Bluetooth settings. So he may want to try that.
