Compensatory Lengthening in Persian: A Perception Experiment

Author

Abstract

This article addresses the perceptual correlates of compensatory
lengthening in Persian. In a perception experiment, duration,
spectral tilt measurements H1-H2 and H1-F1 and F0 were varied in
several steps based on the results from a production experiment
(Sadeghi, 2007). Subjects were asked to identify the tokens
involving vowel length. Results revealed that duration is the most
reliable perceptual correlate of vowel length, and that intensity
level manipulations provide stronger vowel length cues than F0
differences.
