> you need to wait for every second to digest the information in a voice call.

That's highly person-dependent. Some kind of auditory processing disorder runs in my family, and I definitely have it. Under a lot of conditions, I need to spend extra time to digest and understand what has been said.

But not everyone is like this. For a lot of people, hearing is digesting, is understanding.

And like many things, people presume that their own experience is the universal experience- you presume everyone needs to digest, and the person sending you the audio message presumes everyone can process it instantly.
