SURVEY OF THE SPEECH INTELLIGIBILITY IN CHILDREN WITH SPEECH SOUND DISORDERS IN NORTHERN VIETNAM
Main Article Content
Abstract
Objective: This study investigated the speech intelligibility of children aged 4–5 years with speech sound disorders (SSD) in northern Vietnam, using the Vietnamese Intelligibility in Context Scale (ICS-VN). Methods: A total of 51 children were evaluated through caregiver questionnaires and direct assessments, including the ICS-VN, hearing screening, oromotor assessment (OMA), and the Vietnamese Speech Assessment (VSA). Results & Conclusion: The mean ICS-VN score was 3.6 (SD = 0.6). Familiar listeners rated the children’s speech as more intelligible than unfamiliar listeners. ICS-VN scores were negatively correlated with the age at which the child produced their first meaningful word (r = –0.49, p < 0.001).
