How to use AirPods Pro for real-time translation during a Japanese lecture?

I can't figure out how to use translate as I wish to.

Here's a sample scenario. I'm at a lecture where the lecturer speaks Japanese. I'd like to hear his speech through my AirPod Pros (3s are on order) in English. I don't need a transcription.

It seems simple to me to setup but the Apple 'app' hits me as incomprehensible.

I'd like to choose a 'From' and 'To' language and then using an option buttons have the system expect verbal or written input/output. If the Apple system isn't capable of that, please suggest one that is.

I have both an iPhone 17 Pro and AirPods Pro 3s on order if that helps. Thanks for any suggestions.
