| Sumario: | Introduction: Speech perception testing provides an accurate
measurement of the child’s ability to perceive and distinguish
the various phonetic segments and patterns of the sounds.
From among the many types of speech stimuli used, minimal
pairs can also be used to assess the phoneme recognition
skills. Thus, the study focused on developing Minimal Pair Test
in Tamil (MPT-T).
Aim: To develop and validate the MPT in Tamil on Normal Hearing
(NH) children and paediatric Cochlear Implantees.
Materials and Methods: It was an experimental study which
included school going children in the age range of six to eight
years and the duration of the study was 12 months. The test
was developed in two phases. The first phase focussed on the
construction of the word list, recording of the word pairs and the
preparation of the test. The second phase was administration of
the test on NH children and paediatric cochlear implantees. The
test scores were analysed using Mann Whitney U test, Kruskal
Wallis and Wilcoxon signed-rank test. The results showed a
statistical significance between the NH group and the paediatric
cochlear implantees.
Results: The present study included 40 NH children and 15
paediatric cochlear implantees through purposive sampling
method. The specific speech feature analysis of the paediatric
cochlear implantees revealed that there was difficulty identifying
the word pairs differing in Vowel Length (VL) and the best
performed feature was Place of Articulation (POA). The results
showed statistical significance between the NH group and the
paediatric cochlear implantees.
Conclusion: The developed test can be effectively used in clinic
for assessing speech perception abilities of pediatric Cochlear
Implantees and also in planning the rehabilitative goals. |
