I've noticed over the years that whenever I'm in group conversations in a social setting, people in general don't pay too much attention to what I say. For example, let's say the group is talking about travel and someone says something I find relatable e.g. someone mentions a place I've been to and really liked. When I try to contribute to the conversation, people just don't seem interested, and typically the conversation moves on as if I hadn't said anything. If I try to speak for a longer time (continuing with the travel example, let's say I try to talk about a particular attraction I enjoyed visiting at that location), I'm usually interrupted, and the focus shifts to whoever interrupted me.

This has happened (and still happens often) a lot, in different social circles, with people of diverse backgrounds. So, I figure it's not that I hang out with rude people, the problem must be me. I think the saddest part of all this is that even my wife's attention drifts off most of the time I try to talk to her.

I know it's not a language barrier issue, and I know for sure I enunciate my words well. I wonder though if the issue may be that I have a weak voice, or just an overall weak presence/body language. How can that be improved, if that's the case?
