Studies investigating voicing onset time (VOT) production by speakers with aphasia have shown that nonfluent aphasics show a deficit in the articulatory programming of speech sounds based on the range of VOT values produced by aphasic individuals. If the VOT value lies between the normal range of VOT for the voiced and voiceless categories, then…

Background: In Portugal, the routine clinical practice of speech and language therapists (SLTs) in treating children with all types of speech sound disorder (SSD) continues to be articulation therapy (AT). There is limited use of phonological therapy (PT) or phonological awareness training in Portugal. Additionally, at an international level there…

Purpose: The present study was designed to investigate the relation of formant transitions to place-of-articulation for stop consonants. A speech production model was used to generate simulated utterances containing voiced stop consonants, and a perceptual experiment was performed to test their identification by listeners. Method: Based on a model…

Several authors mentioned the occurrence of articulation problems in the neurofibromatosis type 1 (NF1) population. However, few studies have undertaken a detailed analysis of the articulation skills of NF1 patients, especially in schoolchildren and adults. Therefore, the aim of the present study was to examine in depth the articulation skills of…

Purpose: In this study, the authors aimed to investigate how listener training and the presence of intermediate acoustic cues influence transcription variability for conflicting cue speech stimuli. Method: Twenty listeners with training in transcribing disordered speech, and 26 untrained listeners, were asked to make forced-choice labeling…

The goal of this study was to investigate the effects of prosodic stress patterns and semantic depth on word learning. Twelve preschool-aged children with typically developing speech and language skills participated in a word learning task. Novel words with either a trochaic or iambic prosodic pattern were embedded in one of two learning…

The present study aims at analyzing speech samples of four Bengali speaking children with repaired cleft palates with a view to differentiate between the misarticulations arising out of a deficit in linguistic skills and structural or motoric limitations. Spontaneous speech samples were collected and subjected to a number of linguistic analyses…

Foreign accent syndrome (FAS) is an acquired neurologic disorder in which an individual suddenly and unintentionally speaks with an accent which is perceived as being different from his/her usual accent. This study presents an acoustic-phonetic description of two Quebec French-speaking cases. The first speaker presents a perceived accent shift to…

The controlled and free speech of 15 Jordanian male and female children with cleft lip and/or palate was analyzed to account for the different phonological processes exhibited. Study participants were divided into three main age groups, 4 years 2 months to 4 years 7 months, 5 years 3 months to 5 years 6 months, and 6 years 4 months to 6 years 6…

The goal of this dissertation is to explore the phonetic bases of intervocalic lenition--specifically, voicing and spirantization of intervocalic stops. A traditional understanding of phonological patterns like these is that they involve articulatory effort reduction, in that speakers substitute an easy sound for a hard one. Experiment 1 uses a…

The purpose of the present study was to investigate (a) the distortion in production of word-initial friction duration in fricative /[esh]/, and (b) the perceptual discrimination between typical (normal) and atypical (prolonged or lengthened) friction duration. In the first experiment 80 school aged children pronounced word /[esh]uma/, 40 of them…

This article offers a fine-grained investigation of how first-language (L1) phonetics involving English rhotics affect Spanish rhotic production by second-language (L2) learners. Specifically, this study investigates how different L1 English rhotic articulatory routines (retroflex-like and bunched-like) and the phonetic context that produces…

This study focuses on a trilingual toddler's ability to differentiate her Tagalog, Spanish and English productions on phonological/phonetic grounds. Working within the articulatory phonology framework, the word-initial segments produced by the child in Tagalog, Spanish and English words at age 1;10 were narrowly transcribed by two researchers and…

As a subfield of linguistics, phonetics and phonology have as their main axis the concern of articulation of sounds; that is, how human beings produce speech. Although dated back over 2000 years ago, modern contributions of scientists and scholars regarding phonetics and phonology have involved various fields of science and schools of thought such…

Infant phonetic perception reorganizes in accordance with the native language by 10 months of age. One mechanism that may underlie this perceptual change is distributional learning, a statistical analysis of the distributional frequency of speech sounds. Previous distributional learning studies have tested infants of 6-8 months, an age at which…
