What characteristic of a speech gives the audience the knowledge it needs to understand the ideas in the speech?

There are many characteristics of a good speech communication. These are articulation, pronounciation, speech disfluency, speech pauses, speech pitch, speech rate, and speech rhythm. However, among these, articulation is the most important part in the speech. It is because articulation means the way you pronounce each word and the way you express your feelings. Without good articulation, your speech cannot easily be understood and interpreted by your audience.
