It's technically possible to use one of the AI siri voices with latest Taho Betas: a rather interesting finding

Hello.
So I am testing Mac Os Taho on an M1 Macbook Pro, and I have made a rather interesting discovery.
I decided to Install this beta on a separate disk than that of my main OS.
Because of that, unless I chose to import my Voiceover preferences, they would not come over to this version.
So I decided to import my preferences, and discovered that Alex was not working properly, and instead was speaking using Samantha's voice. The only way to get around this appeared to be resetting all Voiceover settings to default, then re-import my preferences.
Normally, when setting up voiceover for the first time or resetting to default preferences, Voiceover is supposed to use Samantha as it's fallback voice, as no other voices are available to use. However, upon initiating default preferences, I discovered something rather interesting.
Instead of using Samantha, Voiceover came up talking using Siri voice 4. But not the normal Siri voice 4 you normally have access too. This Siri Voice 4 is the default Siri AI voice that is used with Apple Intelligence compatible hardware.
The roter entry for this voice says Voice 4, but it isn't the normal voice 4 we are all used to.
II'm not sure if this is intended behavior or not, but either way it is interesting.
SO for those who want to use this voice with Voiceover, the way to do it appears to reset all voiceover preferences, then set them up again the way you had them before. At least that's what worked for me.
It's actually quite a nice voice, probably my favorite of the AI voices.
