Researchers find that smart speakers incorrectly identify wake up words and incorrectly record up to 19 times per day. Echo Dot 2nd Generation and Invoke devices have the longest activations (20-43 seconds)
" How frequently do devices activate? The average rate of activations per device is between 1.5 and 19 times per day (24 hours) during our experiments. HomePod and Cortana devices activate the most, followed by Echo Dot series 2, Google Home Mini, and Echo Dot series 3."
