My hearing id fine. Someone speaks in a normal volume and voice then fades to almost a whisper. I'm compassionatly trying to understand.

Can you please explain this a little more fully?

I have a friend who talks to me distinctly then sort of gradually fades to a whisper. He says he feels depressed and is going through rough times. With his past career where he needed to engage people I don't believe this to be his normal behavior.

Maybe you should enourage your friend you get some professional help, But don't do it in a demeaning way.

How could one suggest in a positive way? Is this behavior evasive or detached? Does it warrant professional help?

The convrsation progresses to a monotone mumble the last one or two sentences. Is this to get attention?
