I often have to repeat a bunch of simple information to people on the phone while they're filling in forms, for example for insurance or medical contacts.

I want to be able to hit a button and have my phone listen and answer their useless questions to endlessly reconfirm my phone number, address, dob etc

It might give a visual display of what it's intending to answer and I have to confirm; it might mute the call and only wake up when it's been asked something it doesn't know. It might completely take over, or it might appear as a third person on the line and not reveal it's synthetic. Anything which can answer these intro questions for me would qualify.

It has to be on Android or the Google successor and has to be free.
