Validation of an Intelligibility Assessment Tool in an Indian Language for Perceptual Speech Analysis in Oral Cancer Patients.

ABSTRACT: This study aimed to develop a speech intelligibility tool in Malayalam, an Indian language, based on the perceptual analysis. The tool had components of vowel, consonant, word, passage, and overall intelligibility. After face and content validation, a sample of 30 consecutive oral cancer patients underwent preliminary testing for internal consistency, inter- and intra-rater reliability, concurrent, and known-group validity. Subsequent validation was done in 80 T1-T4 patients from two centers. The scale had a high level of internal consistency; the Cronbach's alpha was 0.847 and good intra-rater and inter-rater agreement amongst all raters. There was a strong correlation between the Malayalam and the English passage. Pearson correlation coefficient of 0.646 proved concurrent validity. On kn
