Abstract

Introduction: Speech Sound Disorders (SSD) are a common issue in children. Evaluating and intervening in SSD is essential to improve the quality of life for these children. Objectives: To assess the effectiveness of articulation intervention through exercises and pronunciation instructional videos for children with SSD at Children Hospital 1. Methods: This pre-post study was conducted on 30 children with SSD at Children Hospital 1. The analysis included the percentage of consonants correct (PCC) and the Intelligibility in Context Scale (ICS) before and after the intervention. Pronunciation instructional videos were provided to parents, along with guidance from Speech Therapist, enabling parents to practice pronunciation with their children at home. Results: Phonological errors were most concentrated in initial consonants (IC). The average PCC for children at the initial evaluation was 74.6%. The most common initial consonant processes were backing (26.8%) and fronting (14.2%). Processes like aspiration and deaspiration had a frequency of 0.3%. The IC sounds with the highest error frequencies included: /§/ /ÿ/ /t^h/ /x/ /l/ /t/ /s/ /Ä/ /f/ /k/, while the most accurately pronounced IC sounds were: /?/ /b/ /j/ /h/ /m/ /v/ /c/. The analysis of PCC and ICS before and after the articulation exercises showed significant improvement in SSD. PCC increased from 74.6 ±10.5 before the intervention to 84.1 ±11.3 after the intervention. ICS increased from 3.34 ±0.57 to 3.87 ±0.52. Conclusion: Articulation intervention through exercises and pronunciation instructional videos showed significant effectiveness in improving SSD in children. This opens up potential applications for SSD intervention, contributing to an improved quality of life for children and their families
