Apple researchers explore dropping "Siri" phrase & listening with AI instead

The results were promising, according to the paper. The model was able to make more accurate predictions than audio-only or text-only models, and improved further as the size of the models grew larger. Beyond exploring the research question, it's unclear if Apple plans to eliminate the "Hey Siri" trigger phrase. Neither Apple, nor the paper's researchers immediately returned requests for comment. Currently, Siri functions by holding small amounts of audio and does not begin recording or preparing to answer user prompts until it hears the trigger phrase.
