Which of the following factors can change the meaning of spoken words?

Inflection and body language are key elements that significantly impact the interpretation of spoken words. Inflection refers to the modulation of voice, including changes in pitch and tone, which can convey emotions, emphasis, or urgency. For instance, a sentence delivered with a rising intonation at the end can indicate a question, while a flat delivery can suggest a statement. Body language, including gestures, posture, and facial expressions, also plays a crucial role in how a message is perceived. Non-verbal cues often provide context that can alter the intended meaning of the words spoken.

In contrast, while elements like volume, speed, clarity, context, duration, and content hold relevance in communication, they do not encapsulate the same level of impact on meaning as inflection and body language. Changes in volume or speed can affect the delivery but do not intrinsically alter the fundamental meaning of the words. Clarity ensures that the message is understood, while context adds background information, but the immediacy of inflection and body language directly influences how the message resonates with the listener.
