Abstract

Background: Bilabial consonants, produced using both lips, are foundational to speech intelligibility. For children with hearing - loss, articulating these sounds accurately can be particularly challenging because of limited auditory feedback and potential delays in speech development. Objectives:This research paper explores the production of bilabial consonants (/p/, /b/, /m/) in deaf mute children aged 8 to 13 years. The study examines the accuracy of articulation of these consonants in children with varying degrees of hearing loss, including severe to profound sensory neural hearing loss (SNHL) and those with cochlear implants (CI). Methods:Data collected from ten children across different educational levels (first to fourth grade) has been analyzed to understand the impact of hearing impairment on bilabial consonant production. Results:Children with Cochlear Implants generally showed higher accuracy in producing /p/ and /b/ as compared to those with severe to profound S.N.H.L. The ability to produce /m/ was notably lower across all participants. Conclusion:The findings suggest that Cochlear Implants significantly improve bilabial consonant production, but challenges remain in producing the bilabial nasal consonant usually denoted as /m/.
