Communication barriers are obstacles which hamper the communication process. The examples of such are:
Conducting communication in a superior or condescending manner.
Use of fast and routinely expressed questions – this could suggest that you are not really interested in the message that you are receiving.
Rare reference to the thoughts of our interlocutor – such behaviour suggests that you are concentrated more on yourself and your point of view than to the message that you are receiving.
Frequent interruptions for asking questions or meddling comments – it is important to avoid that behaviour as the fluency of the talk suffers in such situations
