Final answer:
The three key components of para-verbal communication are pitch, tone, and volume, each playing a crucial role in how a message is perceived and understood by an audience.
Step-by-step explanation:
The three key components of para-verbal communication are pitch, tone, and volume. Pitch refers to the highness or lowness of a speaker's voice and is a direct reflection of the frequency of the sound waves produced. Tone is the quality of the sound and is influenced by the emotion and attitude behind the speaker's words. Volume refers to the loudness or softness of the spoken words and is closely linked to the intensity of the sound waves.
Effective para-verbal communication requires balancing these elements to ensure clarity and convey the appropriate message. For example, varying the rate of speech can help emphasize important points, while maintaining the right volume ensures the audience can comfortably hear without being overwhelmed or straining to listen. Adjusting the pitch can signal questions, indicate enthusiasm, or signal a change in topic or emotion.
