Speech biometrics can predict cerebellar dysfunction in multiple sclerosis

Abstract

Objective: To objectively describe cerebellar mediated speech function using a multiparameter index that reflects pathology and quality of life in MS. Background: Cerebellar function plays a role in cognitive processing and motor control and is important for speech production. Multiple sclerosis (MS) can result in impaired cerebellar function, leading to speech deficits. These deficits can be detected by instrumental measurement. Speech as a marker of cerebellar impairment but is not well described. Method: The speech and clinical features of 85 people with MS (plus 21 matched controls) were assessed using objective acoustic analysis, validated questionnaires of quality of life and disease..
