Which live caption apps work without the phone's microphone?

Following up on my previous question about voicemail to text, I’ve been investigating live captioning apps. My problem is that I want to use live captioning with my Phonak BT integrated HAs on an Android phone and most of the apps seem to want to use my phone’s built in microphone/speaker phone setup.

Note that any FCC sponsored apps (InnoCaption, CaptionMate, Olelo) are not available to me due to geographic restrictions.

For me, Live Transcribe allows either, selectable in settings. This is on a Pixel 8 Pro with Philips 9050 hearing aids.

Yes, I think that’s a special feature of the Pixel phones. It doesn’t work that way on my Samsung.
