I really hate it when people call for impromptu meetings and are completely oblivious to what you mention. People are absolutely incapable of bridging mental gaps. Nobody explains common vocabulary. Nobody explains the expected goal of conversation. Nobody evens the playing field. Instead, you watch people confused and asking stupid questions, before they arrive at a constructive mental place, right before the meeting is over.

Communication is art and a skill. Just because someone is talking a lot, doesn't mean they communicate well.

If you can efficiently enable a group of people to arrive in a mental context where they can contribute value to a decision or process, you are a valuable team member.

IMHO this always requires preparation. You can't expect to have a valuable exchange if you yourself can't fully imagine the mental context the other people are in. At every moment you have to understand what might be keeping them from understanding you, and then approaching the specific conflict. "Why don't you understand me?" is something you should never have to ask yourself.

Also, yes, build more prototypes and actually watch some shit go instead of talking so fucking much. Pictures are a thousand words and a real thing is like thousands of pictures. Stop talking already!
