“The Nest Hub Max’s latest updates let you use Google Assistant without having to say ‘Hey Google’ ahead of every request.”
“One of the ways that’ll work is with a new feature Google calls ‘Look and Talk.’ Once it’s turned on, you’ll be able to look at the Nest Hub Max’s display and ask a question, no ‘Hey Google’ prompt required. The feature could be a handy way to save some time when you’re already looking at a Nest Hub Max’s screen — I could see it being a useful way to ask for recipes.”
“Look and Talk is an opt-in feature, and you’ll need to have both Google’s Face Match and Voice Match technologies turned on to use it, according to a blog post from Sissie Hsiao, Google’s vice president of Assistant. Audio and video from the Look and Talk interactions will be processed on the device. Look and Talk will be available first on the Nest Hub Max in the US.”
