Effective spoken communication requires being able to express your ideas and views clearly, confidently and concisely in speech, tailoring your content and style to the audience and promoting free-flowing communication.
When we think about spoken communication, we must include things like:
Make effective use of body language and speech. Be sensitive to the other person's body language as well as what they say: eye contact, gestures, appropriate humour and analogies.
Use appropriate body language yourself: face the person with an open, attentive posture and maintain good eye contact (look at the speaker a lot, but don't stare all the time), smile if appropriate and nod your head from time to time.
