It's impossible to use Siri voices for different languages simultaneously in Spoken Content.

Hello,

I want to use Siri voices with Spoken Content for selected text for three languages: English, German and Russian.

I've enabled "Speak selection" and I'm using "Option + Esc" shortcut in order to hear the selected text.

I've also downloaded Siri voices for all three languages.

Now, if I set English Siri voice as a "System Voice" then try to speak selection in English, then I hear English Siri voice - that's ok.

But when I'm trying to select text in German and activate "Speak selection", then I hear not a Siri voice, but some other bad quality voice. The same is for Russian text - voice is bad quality (definitely not Siri).

If I try to set German Siri as "System Voice", then German text sounds good - Siri Voice pronounces it. But now the problem with English text. If I select English text, then it sounds ugly (not Siri). Russian text still sounds bad.

If I try to set Russian Siri as "System Voice", then Russian text sound good (Russian Siri pronounces it), but other two languages sound with some other bad quality voice engine...

I.e. it's impossible to use Siri voice for all three languages simultaneously.

Actually, it's even impossible to use Siri voice even for two languages simultaneously...

My first question is, how to enable Siri voices for different languages simultaneously?

And the second question: why there is no parameter in "Spoken Content" to set a certain voice for a certain language?

Thank you.
