Environment

Latest Community toolkit sample 11.0.0, tried on Android 13, 14 and 15.

Anything else?

Italian language devices, language pack downloaded in italian and english.
Tried:
await speechToText.StartListenAsync(new SpeechToTextOptions
{
Culture = new System.Globalization.CultureInfo("en-US"),
ShouldReportPartialResults = true
}, CancellationToken.None);

to force "en-US" and the default Culture = CultureInfo.CurrentCulture, that picks "it-IT"
