Objective: Speech Impairment occurs in 60-89% in Parkinson’s patients and little is known about as how it affects the
different speech subsystems. In this communication, we report the articulatory kinematics and speech kinematics and speech
dysfunctions in 12 consecutive Parkinson’s patients in scale II and III of Hoehn and Yahr.
Methods: The cross-sectional study on 12 patients aged between 30 and 76 (10 males and 2 females: Hoehn and Yahr scale
II and III) were analysed with Buffalo voice profile to identify laryngeal tone and tension, loudness, pitch and it breaks,
diplophonia, resonance, nasa emissions, rate articulations tests were also done to study plosives, fricatives, affricatives, aspirates,
glides, nasals and blens. Hoehn and Yahr scale IV and V Parkinson’s patients were excluded, patients were video filmed in out
Movement Disorder Clinic.
Results: 25% laryngeal tone abnormality, no vocal abuse, 50% loudness being too soft. Pitch was normal in 33% patients
and phonation duration varied between 5-15 sec (normal being 20); overall speech disturbance was 50%. Eight percent had
plosives error, 33% fricatives error, 8% had affricative error, 8% aspirates error, 8% glide, 8% nasal error and 50% had blends
error.
Conclusion: This study highlighted the monotonous quality, laryngeal tone abnormality and loudness, abnormality associated
with predominant articulation errors in blends and fricatives. This will help us in the quantitative analysis of the effectiveness
of speech therapy in patients with Parkinson’s disease.
