Gaslighting the Spooks?

A number of smartphones have a dictation feature. You speak into the phone and what you say gets rendered, on most occasions, as somewhat legible text.

The phone isn't doing it, of course. Your words are sent to a server, which does the actual work, and then sends the text back to the app that you are using.

The security of that is probably piss-poor. It wouldn't surprise me if there is some algorithm to detect criminality and alert the authorities.

So what would happen if people began gaslighting it? Maybe open a message block, dictate "Jeff is going to buy 50 grams of smack in the high school parking lot tomorrow afternoon" and then delete the draft text. Probably be a good idea if the name that was given wasn't in the list of contacts.
