I can empathize with this. It's a tough thing. However, the main purposes of communication are to connect with the listeners and to convey information to them.

I can empathize with this. It's a tough thing. However, the main purposes of communication are to connect with the listeners and to convey information to them. Speaking in a way that is hard for them to understand makes the communication less effective at both of those things. The best communicators make a deliberate effort to connect with the other participants and adjust the message such that it makes as much sense as possible to them. This can take a lot of practice and empathy to do well.
