Here’s a note from the “Rain” agency:
In the last few months, Google has rolled out several features to position Google Assistant as your go-to for quickly completing tasks on mobile devices. Memory, which is in testing with employees, allows Android users to use voice commands to save anything from pictures and links to screenshots and reminders. April’s Assistant updates let users find their phones with their Nest speaker or smart displays, as well as automatically fill out payment information on the Google Android app for food pickup. Up until now, most of these voice experiences require users to invoke the wake word “Hey Google.”
But this week, the company has been testing a new feature where mobile users can manage alarms and timers without using a wake word — functionality that Google smart display owners have already been enjoying. By eliminating the traditional wake word in these instances, tech companies do open the door to questions about just how many phrases their assistants are passively listening for, and under what circumstances.
