Abstract The aim of the study was firstly to document the acoustic parameters of voice using the Multidimensional Voice Program (MDVP, Kay Elemetrics) in a group of children with dysarthria subsequent to treatment for cerebellar tumour (CT). Then, secondly, compare the acoustic findings to perceptual voice characteristics as described by the GIRBAS (grade, instability, roughness, breathiness, asthenicity, strain). The assessments were performed on 29 voice samples; 9 cerebellar tumour participants with dysarthria, and 20 control participants. None of the control voices were rated as exhibiting any of the six parameters described by the GIRBAS, while 7 of the CT participants were noted to have at least a mild voice disorder. Roughness, instability, breathiness and asthenicity were all identified as voice characteristics in the CT voice samples. Acoustically, the CT voice samples differed significantly from the controls' voices on frequency and amplitude perturbation measures. Our findings confirmed voice dysfunction as a component of dysarthria in children treated for cerebellar tumour, and discussed the links between acoustic and perceptual descriptions.
