Step-by-step explanation:
The average rate of speech for Western cultures is typically around 150 words per minute (wpm). This rate allows speakers to communicate effectively while remaining clear and understandable to the audience. It is important for speakers to maintain a rate that is natural and adjusts for emphasis and dramatic effect, without being overly slow or rapid. Controlling volume and pitch along with rate are crucial for keeping the audience engaged, whether one is speaking softly to convey a tender moment or raising the volume to highlight an important point.
