In Peninsular Ibero-Romance varieties that retain postnuclear lingual fricatives before non-rhotic consonants, loss of the fricative before trills is the norm in colloquial speech. The data in (1a-c) exemplify fricative deletion in Castilian Spanish, Catalan, and Portuguese, respectively, although impressionistic descriptions in the literature often suggest concomitant lengthening of the trill,...

The perceptual dependence of stop consonants on preceding fricatives (Mann and Repp, in press) was further investigated in two experiments employing both natural and synthetic speech. These experiments consistently replicated our original finding that listeners report more velar stops following [s]. In addition, our data confirmed earlier reports that natural fricative noises (excerpted from ut...

background and aim: as the most perceived and articulated errors of hearing aid users occur in high frequency speech phonemes, this study aimed to find a way to amplify and reconstruct the errors. thus, the study first prepared a recorded form of two persian fricative consonants as stimulus; then, the rate of the prescribed gain of the two methods of national acoustic laboratories-nonlinear 2 (...

Standard Mandarin (SM) apical vowels have tongue postures similar to the fricative consonants that obligatorily precede them, but are thought to lack the consonants’ fricative noise. Lee-Kim [10] argues that in SM apical vowels, a slight reduction of constriction at the tongue blade or tip reduces fricative noise, essentially resulting in syllabic approximants. Using lingual ultrasound to exami...

This paper proposes a classification module for fricative consonants in telephone speech using an acoustic-phonetic feature extrapolation technique. In channel-deteriorated telephone speech, acoustic cues of fricative consonants are expected to be degraded or missing due to limited bandwidth. This paper applies an extrapolation technique to acoustic-phonetic features based on Gaussian mixture m...

This study investigates the effect of sub-phonemic variation in bilabial stop and sibilant fricative consonants on word identification. Recent research suggests that sub-phonemic variation in stop voicing contrasts influences lexical processing. The present study seeks further support for this view by examining listeners’ responses to synthetic speech varying along VOT and fricative place conti...

Objectives: The present research aims to study the normal development of Percentage of Consonant Correct (PCC) in Kurdish-speaking children, with Middle Kurmanji-Mukryani Dialect as an Articulation Competency Index (ACI). PCC was examined in terms of the manner of articulation and position of sound in the word.  Methods: In this descriptoanalytical cross-sectional study, 120 Kurdish-speak...
