Aims: The aim of this study is to compare the difference in speech sounds of different phonemes at different syllable positioning observed with conventional and customized palatal contoured dentures. Materials and Methods: A case–control and single-blinded study was conducted on thirty completely edentulous subjects with no previous denture experience. Digital recordings of all subjects were made without denture which served as control, with conventional denture (denture I) and with customized palatal contour denture (denture II) in a sound treated room. The recordings were then compared for phonemes “ch,” “j,” “sh,” “s,” “t,” “d,” “n,” and “l” at initial and middle positions. The permission for conducting the study was taken from the ethical committee. For comparison of both the types of dentures, Chi-square test and for finding inter-examiner reliability, Cronbach's alpha was used. Results and Conclusions: The results showed that there is a difference between the pronunciation of different phonemes at different positions. Customized palatal contour dentures are better for enunciation of middle “ch,” initial “j,” middle “sh,” initial “s,” middle “t,” initial “d,” middle “n,” and initial “l” phonemes and the results were statistically significant. Conventional dentures are better for enunciation of middle “j,” initial “sh,” middle “s,” and initial “t” phonemes and the results were statistically significant. It can be concluded customized dentures prove to be better when compared to conventional dentures. There lies a difference in pronunciation of the same phoneme when it occupies different syllable positioning. It can also be concluded that during any dental evaluation concerning phonetics, a series of words with the same phoneme at different positions should be used for assessment instead of a single word.
