Which aspect of communication does the 'rate' of speech affect?

The 'rate' of speech significantly impacts the clarity of the message being conveyed. When a speaker communicates too quickly, it can lead to misunderstandings as listeners may struggle to process the information at that pace. Conversely, speaking too slowly may cause the audience to lose interest or become impatient, potentially obscuring the key points of the message. By finding an appropriate rate of speech, a speaker ensures that the message remains clear and easy to follow, allowing listeners to grasp the content effectively. This clarity is crucial in facilitating understanding and engagement between the speaker and the audience.
