Final answer:
Speakers who talk too rapidly or too slowly create barriers to effective listening, which hinders audience comprehension and engagement. Effective communication also depends on appropriate volume, pitch, articulation, and fluency, as well as the use of gestures and expressions to enhance messaging.
Step-by-step explanation:
Speakers who talk too rapidly or too slowly may contribute to a barrier to effective listening. An ideal rate of speech should be slow enough to be understood but not so slow that it bores the audience. Likewise, varying the rate can be used for emphasis or to create a dramatic effect. When speech is too rapid, it can be challenging for listeners to process the information, leading to misunderstandings or missed details. If the speech is too slow, it risks losing the audience's attention, making them disengage from the listening process.
Other important elements of effective communication include volume, pitch, fluency, gestures, and articulation. Speakers should maintain appropriate volume and pitch levels, speak fluently without excessive verbal fillers, use gestures and expressions to enhance the message, and articulate clearly to ensure their message is conveyed successfully. Misunderstood or ineffective communication between speakers and their audience, whether due to cultural differences or speech patterns, can lead to barriers in the dissemination and understanding of information.
