SPEECH DETERIORATION OF AMYOTROPHIC LATERAL SCLEROSIS BEFORE AND AFTER DIAGNOSIS:A CASE STUDY OF A NEWSCASTER
This case study traced speech deterioration in an individual around the time of diagnosis of amyotrophic lateral sclerosis (ALS). Our participant was diagnosed with spinal-onset, familial ALS in 2017. The speaker’s occupation, a professional newscaster for 37 years, allowed a retrospective examination of her speech during news segments over 37 months around the diagnosis including pre-diagnosis.
RELATION OF SECOND FORMANT TRAJECTORIES TO TONGUE KINEMATICS
This study examined the relationship between the acoustic and articulatory kinematic domains of speech in 9 neurologically-healthy female speakers using two derived relationships between tongue kinematics and F2 measurements: (1) second formant frequency (F2) extent to lingual displacement and (2) F2 slope to lingual speed. Additionally, the relationships between these paired parameters were examined within conversational, more clear, and less clear speaking modes.
AÂ KINEMATIC ANALYSIS OF COARTICULATION EFFECTS ON SCHWA
This study investigated coarticulatory effects on schwa. The purpose was to establish a viable phonetic environment and analysis for future studies of coarticulation, particularly in motor speech disorders.
A CROSS-LANGUAGE STUDY OF ACOUSTIC PREDICTORS OF SPEECH INTELLIGIBILITY IN INDIVIDUALS WITH PARKINSON'S DISEASE
The study aimed to compare acoustic models of speech intelligibility in individuals with the same disease (Parkinson's disease) and presumably similar underlying neuropathologies but with different native languages (American English and Korean)
ACOUSTIC CHARACTERISTICS OF FRICATIVES /S/ AND /∫/ PRODUCED BY SPEAKERS WITH PARKINSON’S DISEASE
This study investigated acoustic characteristics of fricatives produced in a repeated syllables task by speakers with Parkinson’s disease, focusing on temporal, intensity, and spectral moment analyses.
