@Umi Thanks for the question. Yes, since this feature of Microsoft Translator is app only the tag for the same is not supported on this forum. According to your question from the FAQ link it seems to suggest that this is not the intended use for the App. The transcription and translation quality such as speaker attribution would be discounted because the app is designed for people to use in the same room.
I will check internally if I could help you on this or provide an appropriate forum link. Thanks!!
