Hi everyone, I am currently working on a mapp View project where I need to integrate an AI assistant feature.

My answer was about helping you with secure connection configuration only. I have no idea if there is a way to enable the microphone. Recently, there was a discussion about how to enable text-to-speech using WDTC. Maybe this is the way? I do not know.

Since no additional suggestion has been provided, I think it is time to use the official support channel. If you find any solution, it would be great to update us here.

Thanks @hobi72 , in this case, @jayD ’s support ticket makes no sense. If you would like to go WDTC way, you need to develop and investigate by yourself using publicly available knowledge resources (maybe AI? can help).

Thank you; I shall test it regardless.
