The modulation of lexical competition by segment duration.

The Comprehension of Acoustically Reduced Morphologically Complex Words: the Roles of Deletion, Duration, and Frquency of Occurrence

This study addresses the roles of segment deletion, durational reduction, and frequency of use in the comprehension of morphologically complex words. We report two auditory lexical decision experiments with reduced and unreduced prefixed Dutch words. We found that segment deletions as such delayed comprehension. Simultaneously, however, longer durations of the different parts of the words ap­ p...

Production of English Lexical Stress by Persian EFL Learners

This study examines the phonetic properties of lexical stress in English produced by Persian speakers learning English as a foreign language. The four most reliable phonetic correlates of English lexical stress, namely fundamental frequency, duration, intensity, and vowel quality were measured across Persian speakers’ production of the stressed and unstressed syllables of five English disyllabi...

The Influence of DC-Link Voltage on Commutation Torque Ripple of Brushless DC Motors with Two-Segment Pulse-width Modulation Control Method

The commutation process causes current ripple to be generated in the drive system of brushless DC (BLDC) motor. This, in turn, leads to output torque ripple. Mechanical vibration and acoustic noise are its influences which are undesirable phenomenon in some applications. A new method is presented in this paper which reduces torque ripple and commutation period in the entire range of motor speed...

Segment Duration and Vowel Quality in German Lexical Stress Perception

A perception experiment based on systematic variation of disyllabic vowel duration and vowel quality, and of intervocalic fricative duration in the German minimal lexical stress pair 'Kaffee “coffee” vs. Ca'fé (locality) in a low f0 tail or a high f0 plateau shows highly significant effects of the 3 variables as cues to lexical stress. The combined vowel quality and fricative variables outweigh...

Visual - shape competition during language - mediated attention is based on lexical input and not modulated by contextual appropriateness
