Current Behavior

I'm unable to get speech to text recognition with polish language, it works perfectly fine offline or online with "en-US". It throws "Request language is not supported error".
THIS REFERES TO ANDROID AND WINDOWS!

To my dismay, this feature works on Samsung A54 and with their native polish library, however with google package it's unable to work.

This is what i tried in code:
await _speechToTextService.StartListenAsync( new SpeechToTextOptions() { // Culture = CultureInfo.GetCultureInfo("PL") // Culture = CultureInfo.CurrentCulture, Culture = CultureInfo.GetCultureInfo("pl-PL"), ShouldReportPartialResults = true, }, CancellationToken.None );

Also I've tried changing current culture of my PC to Polish and it petered away.

These are my windows settings:

I managed to debug external sources and here's the exact line when the error is thrown:
It's 117 line of SpeechRecognizer.cs (scenario with online speech recognition)

Expected Behavior

Being able to use speech to text with polish language, on windows 10/11 and android.

Steps To Reproduce

1. Open and run solution.
2. Press "Start the speech" button.
3. Error should be displayed in a label below.

duplicate #2463

@VladislavAntonyuk I thoroughly looked into #2463 before I had created my issue. It seems like #2463 have found workaround his problem. I've tried his solution and it wouldn't work for Polish. Please reconsider looking into my problem again :)
