Talkback doesn't work when app is recording audio via AudioRecord

On the latest one UI system, talkback doesn’t read anything on screen if app is recording audio via AudioRecord. Is this a bug or an over-designed feature?

Our app has a voice assistant that supports keyword spotting (voice activation like “ok google”/“hey siri”) which requires recording audio all the time when app is in the foreground. This talkback bug is blocking user from hearing talkback.
