Support for Azure TTS Multilingual Voices

[v1k70rk4]

Hello, this is not a problem, but a question or a request for support.

My problem is that multilanguage languages have appeared in Azure TTS, and my question is whether the program can handle it. As I see it, HomeAssistant uses this component and I am in trouble with the use of multilang languages.

If it is not supported, I would ask if it is possible to implement this. The quickest would be a secondary_language option and it would put the whole text into this lang xml child:

Example:

<speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis" xmlns:mstts="https://www.w3.org/2001/mstts" xml:lang="en-US">
    <voice name="en-US-JennyMultilingualV2Neural">
        <lang xml:lang="de-DE">
            Wir freuen uns auf die Zusammenarbeit mit Ihnen!
        </lang>
    </voice>
</speak>

Of course, it can be made more complicated, such as having multilingual Texts in one text, but I would be very happy with this too :)

Thank you in advance for your response.
