Purpose: Reduced intensity is a hallmark of speech production in Parkinson's disease (PD). Previous work has examined the perception of intensity in PD to explain these speech deficits. This study reports loudness ratings of pure tones by individuals with PD and controls, all with normal thresholds for older adults. Method: Twenty individuals with…

Klein, Harriet B.; McAllister Byun, Tara; Davidson, Lisa; Grigos, Maria I. – American Journal of Speech-Language Pathology, 2013
Purpose: This study explored relationships among perceptual, ultrasound, and acoustic measurements of children's correct and misarticulated /r/ sounds. Longitudinal data documenting changes across these parameters were collected from 2 children who acquired /r/ over a period of intervention and were compared with data from children with typical…

Laaksonen, Juha-Pertti; Rieger, Jana; Harris, Jeffrey; Seikaly, Hadi – Clinical Linguistics & Phonetics, 2011
Acoustic properties of 980 tokens of sibilants /s, z, [approximately]/ produced by 17 Canadian English-speaking female and male tongue cancer patients were studied. The patients had undergone tongue resection and tongue reconstruction with a radial forearm free flap (RFFF). The spectral moments (mean, skewness) and frication duration were analysed…

Sussman, Harvey M.; Byrd, Courtney T.; Guitar, Barry – Clinical Linguistics & Phonetics, 2011
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…

Awan, Shaheen N.; Helou, Leah B.; Stojadinovic, Alexander; Solomon, Nancy Pearl – Clinical Linguistics & Phonetics, 2011
This study evaluates the utility of perioperative spectral and cepstral acoustic analyses to monitor voice change after thyroidectomy. Perceptual and acoustic analyses were conducted on speech samples (sustained vowel /[alpha]/ and CAPE-V sentences) provided by 70 participants (36 women and 34 men) at four study time points: prior to thyroid…

Tjaden, Kris; Sussman, Joan – Journal of Speech, Language, and Hearing Research, 2006
Purpose: This study addressed three research questions: (a) Can listeners use anticipatory vowel information in prevocalic consonants produced by talkers with dysarthria to identify the upcoming vowel? (b) Are listeners sensitive to interspeaker variation in anticipatory coarticulation during prevocalic consonants produced by healthy talkers…
