HyperTTS in Anki doesn't reliably apply the ElevenLabs API to render Argentine Spanish on the back template

[fetito]

Hello!
I’m trying to configure HyperTTS in Anki so that the ElevenLabs API consistently uses Argentine Spanish on the back template.

Sometimes it defaults to Portuguese TTS instead—are there specific ElevenLabs tags or settings I should be aware of to prevent this?

Using Mexican Spanish as an alternative would be fine too.

I’ve attached a screenshot for reference.

Thanks in advance!

Here is the code:

<div lang="es-AR">
{{FrontSide}}

<hr id=answer>

<img src="argentina_flag.png" style="width:30px;"><br>
{{Back}}
</div>

Could you also provide the content of the fields?

Hi. I replied to you on reddit, there will soon be a fix which allows specifying the language code using the Eleven Labs API. For the time being I recommend using language specific voices if you need accuracy in non English languages.
Even when that fix is implemented, you may find that multilingual models such as Eleven Labs have an American English accent when pronouncing non English languages.
