It’s just a rumor right now, but it’s got some interesting sources behind it.
Developers Guilherme Rambo and Stephen Troughton-Smith, who’ve been exploring the macOS, have found references to the “Hey Siri” function in the code base with support for multiple user accounts, just as macOS has long supported user switching.
At present, it’s been rumored that the iMac Pro could feature an A10 Fusion coprocessor which could manage the “Hey Siri” functionality as well as the boot process, security, and the FaceTime camera. It also appears that the inclusion of the A10 Fusion allows the iMac Pro to accept the voice command ‘Hey Siri’ rather than requiring the click in macOS on the Siri icon or keystroke to prompt Siri.
This doesn’t mean necessarily that Siri will understand multiple users speaking while logged into one macOS user account. But, it may mean that if a user has multiple accounts on a Mac, they should be able to fast user switch between them and have the iMac Pro recognize ‘Hey Siri’ for each of them.
It’s presently unclear as to whether this functionality would require a coprocessor like the A10 Fusion to be implemented in other future Macs down the line.
Stay tuned for additional details as they become available.
