Siri Stopped Working On MacBook Air

Siri had been working fine, but today I tried and cannot invoke Siri on my MacBook Air.

Not by voice and not by selecting the app and not by invoking the associated keyboard shortcut.

I recently had an update to macOS Sonoma 14.7. Not sure if that caused the issue or not.

Everything else seems to be working just fine on the computer. Siri is working just fine on my iPhone.

Some things I tried - to no avail:

• Rebooted the Macbook.
• Turned off/on Siri in System Settings
• Turned off/on Listen For Hey Siri in System Settings.
• Turned off/on Siri in iCloud
• Deleted Siri history in iCloud
• Confirmed no time of day restrictions in place.
• Turned wifi off/on.
• Checked sounds are adjusted properly input/output.
• Rebooted again, just to be sure.

None of these were successful.

When I say "Hey Siri", I get no response from the Mac. When I try just invoking Siri by the icon on the top of the screen or by clicking on the App icon, or invoking the keyboard shortcut, it just makes a downward bloopinng sound that corresponds to something not working, and nothing more.

When I turn off/on Siri and Listen for Hey Siri in settings, it asks if I want to set up Hey Siri. I select continue and asks me say "Hey Siri, How's the Weather". It then indicates that Siri did not quite get that and asks me repeatedly to try again, until I eventually hit the cancel button.

I am at a loss as to what to do further. Not sure if others have this issue too. Any OPEX / resolutions would be appreciated. Thanks in advance for your support.
