摘要:The objective of this work is to study the voice onset time (VOT) and the speed oftransitions in diphthongs through the slopes of F2 in ataxic dysarthria, in additionto examining the relationship between these two acoustic measurements andseverity of motor speech disorders.The results show higher VOT and greater variability and slower transitions in thedysarthric group. High correlation between these two measures and the level ofspeech intelligibility was found.Acoustic analysis has proved a useful tool for objective assessment of dysarthria.The two measures used in this study provide information on the severity of motorspeech disorders and provide objective data that can be used in speech therapy andresearch.
