Communication can be improved by closely listening to what the people or person you are communicating with are saying. If you are being alert and truly listening to what they have to say, this will make you a good communicator on your part as a listener. When you are speaking, you can have good body language like maintaining eye contact, good posture, etc., so the person who is listening to you is aware that you want to be heard. As the communicator, you also have to make sure you get your point across, so you can be understood as perfect as possible.
