Journal of Medical Speech - Language Pathology archives from December 2004

Preface to special issue.
December 1, 2004... This issue of the Journal of Medical Speech-Language Pathology contains a compilation of articles presented at the Conference on Motor Speech held in March 2004 at Albuquerque, New Mexico. This meeting was the most recent of a series of...

Jaw and finger movements during visual and auditory motor tracking in Parkinson disease.
December 1, 2004... Audiomotor and visuomotor tracking paradigms were used to evaluate differences in oral and upper limb motor deficits in Parkinson disease (PD). Ten PD subjects and 10 normal controls (NC) used their jaw and index finger to track visual targets...

The effects of delayed and frequency shifted feedback on speakers with Parkinson disease.
December 1, 2004... Delayed auditory feedback (DAF) has been assessed as a rate reduction and intelligibility enhancing tool in patients with Parkinson disease (PD) for some time. However, there are contradictory results in the literature regarding the success of...

Articulatory imprecision in dysarthria following childhood cerebellar tumor: a perceptual and acoustic investigation of three male participants.
December 1, 2004... Articulatory imprecision has been documented as a key perceptual feature of the dysarthria associated with childhood cerebellar tumor (CCT). As yet the underlying acoustic and physiological characteristics of motor speech production that...

Effects of spontaneous gestures on comprehension and intelligibility of dysarthric speech: a case report.
December 1, 2004... Many speakers with dysarthria benefit from the use of strategies that provide additional contextual information to listeners, such as the use of hand gestures (gesticulations) while speaking. Less is known about the effect of spontaneous...

Algorithmic estimation of pauses in extended speech samples of dysarthric and typical speech.
December 1, 2004... The aim of this study was to evaluate the validity and performance of an algorithm designed to automatically extract pauses and speech timing information from connected speech samples. Speech samples were obtained from 10 people with...

Nasal obturator for velopharyngeal dysfunction in dysarthria: technical report on a one-way valve.
December 1, 2004... Velopharyngeal dysfunction is frequently associated with motor speech disorder. Palatal lift prostheses are an accepted intervention for velopharyngeal dysfunction that is not responsive to behavioral interventions (Yorkston et al., 2001)....

Listener attitudes toward speech supplementation strategies used by speakers with dysarthria.
December 1, 2004... This study examined listener attitudes toward (1) habitual speech, (2) alphabet supplemented speech, (3) topic supplemented speech, and (4) clear speech produced by nine survivors of traumatic brain injury who had dysarthria at varying levels...

Diagnostic assessment of childhood apraxia of speech using automatic speech recognition (ASR) methods.
December 1, 2004... We report findings from two feasibility studies using automatic speech recognition (ASR) methods in childhood speech sound disorders. The studies evaluated and implemented the automation of two recently proposed diagnostic markers for suspected...

Spectral analysis of hypernasality.
December 1, 2004... The aim of this study was to further investigate one-third-octave analysis by (a) extending the application of the analysis to three vowels, /[TEXT NOT REPRODUCIBLE IN ASCII]/, /[TEXT NOT REPRODUCIBLE IN ASCII]/ and /u/, in addition to /i/...

Variability within and across physiological systems in dysarthria: a comparison of STI and VOT.
December 1, 2004... There are many sources of variability within the speech production system. It is not known if variability within a system is associated with variability across physiological systems. In this investigation, eight individuals with dysarthria and...

The effect of three practice conditions on the consistency of chronic dysarthric speech.
December 1, 2004... This study investigated whether it is possible for people with chronic dysarthria to adjust their articulation in three practice conditions. A speaker dependent, speech recognition system was used to compare participants' practice attempts with...

The acoustics of contrastive prosody in adults with cerebral palsy.
December 1, 2004... Recent studies have documented that adults with cerebral palsy can control prosodic features such as pitch, loudness, and duration despite severely impaired segmental control. Although their productions are restricted in range, they are able to...

The effects of pallidotomy surgery on sentence measures across three tasks in Parkinson patients.
December 1, 2004... Experimental and clinical evidence suggest that limb motor symptoms of human Parkinson disease (PD) can be surgically ameliorated by pallidotomy. However, the results of this surgery on speech motor symptoms have been equivocal. Acoustic...

Fundamental frequency (F0) measures comparing speech tasks in aphasia and Parkinson disease.
December 1, 2004... Mean fundamental frequency (F0) and F0 variability were studied in Broca, Wernicke, anomic aphasic, Parkinson, and normal control subjects, performing four speech tasks: reading, conversation, counting, and sustained vowel phonation (mean F0...

Speech-breathing treatment and LSVT for a patient with hypokinetic-spastic dysarthria after TBI.
December 1, 2004... Previously, we reported improved speech breathing and intelligibility after behavioral treatment for a man with hypokinetic-spastic dysarthria following traumatic brain injury (TBI) (Solomon, McKee, & Garcia-Barry, 2001). Treatment included the...

Variability in apraxia of speech: a perceptual and VOT analysis of stop consonants.
December 1, 2004... This investigation was designed to examine the effects of (1) method of stimuli presentation and (2) sampling over time on production of stop consonants with a speaker with acquired apraxia of speech. Stimuli were presented in a blocked format...

Perceptual and acoustic predictors of intelligibility and acceptability in Cantonese speakers with dysarthria.
December 1, 2004... The primary aim of this study was to determine contributing factors to listener judgments of acceptability, a global measure of severity, in speakers with dysarthria. Participants included 33 Cantonese speakers with dysarthria, ages 14-78...

Service delivery variables and outcomes of treatment for hypokinetic dysarthria in Parkinson disease.
December 1, 2004... Treatment to increase vocal loudness was provided to 11 individuals with hypokinetic dysarthria as a consequence of Parkinson disease. Participants were assigned to one of three treatment schedules: four times per week for 4 weeks, two times...
