To clarify speech-elicited response patterns within auditory-responsive cortex of the posterolateral superior temporal (PLST) gyrus, time-frequency analyses of event-related band power in the high gamma frequency range (75-175 Hz) were performed on the electrocorticograms recorded from high-density subdural grid electrodes in 8 patients undergoing evaluation for medically intractable epilepsy. ...

The study was conducted to provide an acoustic description of coronal stops in Canadian English (CE) and Canadian French (CF). CE and CF stops differ in VOT and place of articulation. CE has a two-way voicing distinction (in syllable initial position) between simultaneous and aspirated release; coronal stops are articulated at alveolar place. CF, on the other hand, has a two-way voicing distinc...

The aim of this experiment was to examine the preattentive processing of syllables in 9-11-year-old children with dyslexia and matched controls using the Mismatch Negativity (MMN), an auditory Event-Related brain potential (ERP) related to preattentive discrimination. Children were presented with a sequence of syllables that included standards (the syllable "Ba") and deviants in vowel frequency...

   Objectives: The present study aimed at investigating the relationship between Dysphonia Severity Index (DSI) and disease speech and voice severity of Parkinson disease (PD) patients. Method. This study was a cross-sectional ones, carried out on 45 PD patients with the age range of 50 to 75 years, who were randomly selected. The Hoehn and Yahr Scale (H.Y Scale) was employed to measure the le...

A perception experiment on stop consonant voicing in (C)V1CV2 was conducted to test the effects of the preceding vowel. Five types of /ki/ as CV1 differing in closure voicing, vowel duration and vowel devoicing were spliced with a da-ta VOT continuum as CV2. Subjects’ judgment between the spliced kita and kida along a VOT range was compared with that of ta and da in isolation. Strong effects of...

This study compares the VOT measurements between Persian and English stutterers. The speech samples of five adult stutterers (four males and one female) of each language were recorded during a reading task. 98 stuttering events in words beginning with plosives and 34 fluent plosives (i.e., final fluent iterations following the stuttered portions of speech) were identified in the data of both gr...

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...
