When speaking, insert punctuation so that the audience ‘hears’ commas, semi colons, and full stops. This is achieved through pause which adds the emphasis punctuation is about.
Pause is a way of emphasising important points that have been made. To pause gives listeners a brief reflective space. In that context ‘pause’ is a way of emphasising elements of speech.
‘Inflection’ is a way of building emphasis and highlighting points that are being made. This adds to the vibrancy of speech and triggers listening reception that helps to make points ‘stand out’ in audience comprehension.
