Which term is the cover term for the combined effect of pitch, loudness and length?

• A. Stress
• B. Prosody
• C. Tone
• D. Intonation

Answer: (A)

Stress is the feature that marks prominence on a syllable or word, and it’s realized through a combination of pitch, loudness, and duration. When a syllable is stressed, the voice typically rises in pitch, becomes louder, and is held a bit longer, making that unit stand out in speech. This combined effect helps listeners notice which syllables or words are most important in a phrase, guides timing and rhythm, and can even affect meaning in some languages.

Prosody is the broader system that covers all speech patterns—rhythm, pitch movement across phrases, loudness changes—while tone and intonation refer to specific pitch patterns. The idea here is that the emphasized syllable’s overall prominence is captured by stress, since it directly ties together pitch, loudness, and length to mark importance.
