“Hey Siri”

Monday, 23 October, 2017

Apple has published a a paper on how its devices listen for people using the “Hey Siri” command/query. There’s a lot of machine learning going on here:

“The ‘Hey Siri’ detector uses a Deep Neural Network (DNN) to convert the acoustic pattern of your voice at each instant into a probability distribution over speech sounds. It then uses a temporal integration process to compute a confidence score that the phrase you uttered was ‘Hey Siri’. If the score is high enough, Siri wakes up. This article takes a look at the underlying technology. It is aimed primarily at readers who know something of machine learning but less about speech recognition.”

Note: Apple says: “Hey Siri” works in all languages that Siri supports, but “Hey Siri” isn’t necessarily the phrase that starts Siri listening. For instance, French-speaking users need to say “Dis Siri” while Korean-speaking users say “Siri 야” (Sounds like “Siri Ya.”) In Russian it is “привет Siri” (Sounds like “Privet Siri”), and in Thai “หวัดดี Siri”. (Sounds like “Wadi Siri”.)
