Choose my language in conversation dialog instead of harcoded "en-US"

would love to choose my language in conversation dialog. Now you use google speech-to-text integration with hardcoded “en-US” language. By the way google supports more languages to recognize. It’l be great if you add this feature. Thanks.

The tts.cloud_say service allows you to do this. Could you do something with that?

no. you are talking about tts, and i about stt in conversation dialog
