AudioTranscribeAzureSettings.targetLanguages property
The target output languages for translation - technically a BCP 47 language tag but but in most cases omitting region, e.g. en, de, zh-Hant.
Leave this field absent/empty to use the transcription service without translation, while if any target languages are present the translation service will be used even if this is the same as the source language.
