What does the term 'affective prosody' refer to?

Affective prosody specifically refers to the emotional tone expressed in speech. This includes variations in pitch, loudness, tempo, and rhythm that convey feelings and emotional states, such as happiness, sadness, anger, or excitement. It is a crucial component of verbal communication as it provides context that helps listeners interpret the speaker's intentions and emotional state beyond the literal meaning of words.

In contrast, the other choices focus on different aspects of speech. Clarity of speech sounds pertains to the articulation and precision of phonemes, which is more related to speech intelligibility rather than emotional expression. Grammar and syntax involve the rules governing sentence structure and the order of words, which do not relate to emotional delivery. Lastly, physical movement in speech pertains to the articulatory actions involved in producing sounds, which while necessary for speech production, does not address the emotional nuances conveyed through affective prosody.
