This study assessed the acoustic coarticulatory effects of phrasal accent on [V1.CV2] sequences, when separately applied to V1 or V2, surrounding the voiced stops [b], [d], and [g]. Three adult speakers each produced 360 tokens (six V1 contexts x ten V2 contexts x three stops x two emphasis conditions). Realizing that anticipatory coarticulation of V2 onto(More)
Previous studies investigating anticipatory coarticulation in emphatically stressed CV sequences and during fast speaking rates reported that three factors contributed to the overall extent of the documented coarticulation. These factors were: (1) vowel identity, (2) vowel space expansion (emphasis) or reduction (fast rate), and a hypothesized (3) 'deeper'(More)
In 2007 Lindblom et al. introduced a methodological tool to disentangle consonant-vowel (CV) coarticulation attributable to emphatic stress apart from the vowel expansion effects known to accompany the prosodic overlay. After empirically accounting for the altered vowel positions, they reported small but consistent increases in F2 transition onsets in(More)
UNLABELLED Three children with developmental apraxia of speech (DAS) identified the number of syllables in words, judged intrasyllabic sound positions, and constructed syllable shapes within monosyllabic frames. Results suggest that DAS children demonstrate an apparent breakdown in the ability to perceive "syllableness" and to access and compare syllable(More)
A speculative model for representing phonological categories for stop place of articulation is offered. The model is analogous to neural columns in both inferotemporal cortex in the macaque for achieving constancy in object recognition and in the inferior colliculus of the barn owl for resolving ambiguous phase disparities for sound localization.(More)
This article analysed the acoustic structure of voiced stop + vowel sequences in a group of persons who stutter (PWS). This phonetic unit was chosen because successful production is highly dependent on the differential tweaking of right-to-left anticipatory coarticulation as a function of stop place. Thus, essential elements of both speech motor planning(More)
Fifteen children diagnosed with specific language impairment (SLI) and 15 typically developing (TD) children were tested for identification performance on 2 synthetic speech continua varying in formant transition durations (FTDs). One continuum varied from /ba/ to /wa/, and the other varied from /da/ to /ja/. Various d'-related measures from signal(More)
