Jul 26, 2020 at 21:31 comment added Peter Cordes Fun fact: some cheaper Android phones don't have a dedicated audio processor to listen for the equivalent "Hey Google" or "Ok google", so it does cost significant power to enable always-on listening for that phrase. (Android makes it optional.) But yes, having a unique phrase of more than 2 syllables before firing up the full power of speech-to-text processing is important for saving power, as well as minimizing false positives so you can talk about siri with another human without your phone jumping in!
