Abstract
The deep test of articulation is a diagnostic articulation test which tests the phonemes in all possible position and in all possible phonetic contexts. At
present deep tests of articulation are available only in Kannada (Rohini, 1989) and Malayalam (Maya, 1990) among the Indian languages. India being a
multilingual country, it is necessary to have articulation tests in different languages. In this context, the present study aimed to develop deep test of
articulation in Bengali language. For this 11 key phonemes were selected /t/ /d/ /k/ /g/ /d/ /c/ /j/ /s/ /r/ /l/ and /h/ based on articulation test in Bengali developed
by Arun Banik (1988). Meaningful picturable easy words were prepared with these phonemes in initial and final positions.
