How to set language? (italian)

[washburnit]

Hi,
I'm new with this package, I've made a small program (based on your example source) that interacts with Azure OpenAI but I would like to use "real time audio" acquisition with MS Cognitive Services (I have an active subscription for Azure).
Cognitive Services "translate" the spoken language into a text (speech-to-text) that I "send" to OpenAI GPT (4).
I need to set the language (in my case "italian") to interact with OpenAI but I didn't find the way to do it through the source code (C#).
How could I do it?
I'm using the "ChatCompletionTestHelper" file example.
Thank you, regards.
