Comparaison d'analyses phonétiques de parole dysarthrique basées sur un alignement manuel et un alignement automatique

Abstract : The reliability of an automatic speech alignment procedure for the phonetic description of dysarthric speech is assessed through the comparison of durational and spectral measurements obtained from an automatic and a manual alignment of the production of 4 dysarthric speakers varying in severity. Results show that formant values computed in the middle of the vowel intervals and center of gravity of fricative noise computed over the consonant intervals, are reliable when based on automatic alignments. However, the analysis of pause occurrences and absolute segmental duration require manual corrections of the automatic outputs.
