YugTalk: A Filipino-Based Augmentative and Alternative Communication Mobile Application for Pediatric Patients with Speech Disorders

This study presents the development and evaluation of YugTalk, an innovative Filipino-based Augmentative and Alternative Communication (AAC) mobile application designed for pediatric patients with speech disorders. Utilizing the Flutter framework and Firebase backend, YugTalk introduces unique features that address the critical need for culturally relevant AAC solutions in the Philippines. The app's cornerstone features include a Symbol Pop-up with integrated Video Pronunciation, offering visual and auditory cues for proper articulation in both Filipino and English. A comprehensive Activity Mode transforms the app into a therapeutic tool, allowing customized exercises, progress tracking, and gamified learning experiences. These features integrate with core AAC functionalities, such as customizable communication boards and text-to-speech capabilities. A quasi-experimental pre-test/post-test study involving pediatric patients aged 3-5 years demonstrated significant improvements in communication skills, with one patient showing statistically significant progress (p = 0.002) in standardized language assessments. YugTalk achieved high usability scores across all user groups, indicating its effectiveness as both a communication aid and a therapeutic tool. This research contributes to assistive technology by providing a feature-rich, culturally sensitive AAC solution that enhances communication skills and supports speech therapy for Filipino children with speech disorders.
