Acoustic analysis of voice in spastic dysarthria: Case report ABSTRACT Voice analysis in dysarthria is challenging because of the complexity of the disorder and its affects on the speech production system. A combination of perceptual and acoustic analysis is increasingly common because of its convenience. The aim of this report is to perform the voice analysis in 66 years old male diagnosed as spastic dysarthria. Based on the assessment we can conclude that voice analysis reveals interesting data on the multiplicity of voice quality in spastic dysarthric. Key words: dysarthria, acoustic analysis, voice quality INTRODUCTION Vocal analysis in individuals with neurological disease can make an important contribution towards reaching a differential…show more content…
The GRBAS stands for Grade, Roughness, Breathiness, Asthenia and Strain assessed by a 4 point rating scale where 0 stands for normal and 3 stands for severe.[3] Table 1: Representation of scores in GRBAS Parameters Rating Impression Grade 2 Moderate Roughness 1 Slight Breathiness 2 Moderate Aesthenia 2 Moderate Strain 1 Slight From table 1, it is evident that the perceptual rating on GRBAS revealed that GV had a Grade, Breathiness and asthenia revealing moderate level of voice problem but voice quality is only impaired slightly for parameters like roughness and strain. Buffalo III Voice Profile was used to measure laryngeal tone, pitch, loudness, nasal resonance and an overall voice rating. It is scored using a 5-point scale ranging from 1 being normal to 5 being very severe.
