Which of the following acoustic characteristics is/are applicable to the vowel /i/?
Show Hint
- Periodic waveforms
- Voice Onset Time (VOT)
- Formants
- Voicing
The Correct Option is A, C, D
Solution and Explanation
Step 1: Understand the nature of the vowel /i/.
The vowel /i/ is a high front unrounded vowel. It is voiced and produced with a relatively stable vocal tract configuration.
Step 2: Evaluate each acoustic feature.
(A) Periodic waveforms – Yes. Vowels, being voiced, exhibit periodic patterns.
(B) Voice Onset Time (VOT) – No. VOT applies to the time lag between release and voicing in stop consonants, not vowels.
(C) Formants – Yes. Vowels are characterized by distinct resonant frequencies known as formants (especially F1 and F2).
(D) Voicing – Yes. The vowel /i/ is voiced. Conclusion: Options (A), (C), and (D) apply to /i/.
