Question

Voice Onset Time (VOT) is an acoustic cue used by our auditory-perceptual systems. Which of the following sounds can be identified using VOT?
(i) Voiced Stops
(ii) Unvoiced Stops
(iii) Prenasalised Stops
(iv) Aspirated Stops
(v) Ejective Stops

• A. (i), (ii), (iv) but NOT (iii) and (v)
• B. (i), (ii), (iii), (iv) but NOT (v)
• C. (iv), (v) but NOT (i), (ii) and (iii)
• D. (i), (iii), (v) but NOT (ii) and (iv)

Hint:

VOT is crucial in distinguishing stop consonants across many languages.

Answer 1

The Correct Option is A

Step 1: Understanding VOT.
Voice Onset Time refers to the time interval between the release of a stop consonant and the onset of vocal fold vibration.
Step 2: Sounds identifiable using VOT.
Voiced stops, unvoiced stops, and aspirated stops differ primarily in their VOT values, making them perceptually distinguishable.
Step 3: Exclusion of prenasalised and ejective stops.
Prenasalised stops involve nasal airflow before oral closure, while ejective stops use glottalic mechanisms, not VOT-based contrasts.
Step 4: Conclusion.
Hence, option (A) is correct.
