Apple is supposedly looking to swap Siri's trigger phrase. Instead of "Hey Siri," the company just wants you to use "Siri." Bloomberg's Mark Gurman reported that this feature has been in the works for the past several months, and it's expected to come out next year or in 2024. But Apple needs to put in a "significant amount of AI training and underlying engineering work" to get this feature to function properly. Its smart assistant will need to understand that single wake word in different accents and dialects. The "Hey Siri" two-word trigger phrase has a better chance of the smart assistant picking it up.
Changing to the single wake word will put Apple in line with Amazon's Alexa and give it an edge over Google Assistant. But the latter doesn't need the wake word when you're saying back-to-back commands. Aside from the shorter trigger phrase, Apple is exploring third-party integration for Siri and improvements in its ability to process user requests.
