Could you connect with someone only through audio conversation?

Hey everyone, I am doing market fit for the app that would be limited only to the audio experience. I hypothesize that removing visuals, focusing only on audio could lead to a more meaningful connection. On the other hand, this approach would require more input from the subject itself. The main question is if the reward you can get from such a talk would justify the input needed to get it. What are your thoughts on the subject? Thanks for sharing!
