CHiP can hear you! To get his attention, all you have to do is say "Hey CHiP". Once his eyes turn green, you know he's listening.
Voice recognition technology is sometimes a bit finicky.
If it seems like CHiP isn't listening at times, it might have something to do with pitch, and intonations in speech.
Luckily, any trick that can be activated through voice is also accessible through the SmartBand and the CHiP app.
