In the study related to loudness and prosodic variables, which acoustic variables were examined?

• A. Vocal intensity and speech clarity
• B. F0 declination and final-word lengthening
• C. Monosyllabic word intelligibility
• D. Overall speech duration and volume

Answer: (B)

The focus on F0 declination and final-word lengthening as the correct choice highlights the essential role of prosodic features in speech. F0 declination refers to the gradual lowering of pitch over the course of an utterance, which is a critical element of natural prosody and contributes to the listener's ability to perceive sentence structure and emphasis. Final-word lengthening involves extending the duration of the last word in a phrase or sentence, drawing attention to it and often signaling the end of a thought. This practice is common in spoken language and helps convey meaning and emotional tone, thus influencing the overall interpretation by the listener. In contrast, while vocal intensity and speech clarity, monosyllabic word intelligibility, and overall speech duration and volume all relate to aspects of speech, they do not specifically capture the nuanced dynamics of loudness and prosodic variations that enhance communicative effectiveness. Focusing on the prosodic elements of F0 declination and final-word lengthening aligns well with the study of how these variables interact with and affect perceived loudness in speech.
