Palatometry was used to obtain measures on certain production parameters of the coronal consonants /t/, /ʃ/ and /tʃ/ of Hindi. Results show that the average area of tongue-palate contact was considerably greater for the stop part of the affricate than for the stop. However, the anterior-posterior (A-P) length of the central constriction was much narrower for the stop part of the affricate than for the stop. Some overlap in the A-P location (place) of the central constriction between the stop and the stop part of the affricate was observed. The central constriction for the stop part of the affricate was formed in the prealveolar zone, whereas for the stop it was formed in the dental zone and a part of the prealveolar zone. On average, the area of tongue-palate contact was also somewhat greater for the fricative part of the affricate than for the fricative. However, the side-to-side (S-S) width of the groove and the A-P location of the groove center were the same for both the fricative /ʃ/ and the fricative part of /tʃ/.
