Abstract:

Despite the increasing availability of assistive communication technologies, hearing-impaired individuals continue to experience communication barriers in daily interactions due to limited access to affordable, accessible, and efficient tools. This study aimed to develop and evaluate a mobile-based speech-to-text and response communication system designed to improve communication effectiveness between hearing-impaired and hearing individuals. The study utilized a developmental-evaluative research design with a one-group pre-test and post-test approach. The application was developed using Flutter and Dart, following the Agile Software Development methodology, and deployed as an offline Android application. Twenty hearing-impaired individuals from San Jose, Occidental Mindoro, participated in the evaluation. The system was assessed on text accuracy, system response time, ease of use, response selection efficiency, and question selection usefulness. Findings revealed significant improvement in communication effectiveness after using the application, particularly in message comprehension, response appropriateness, and communication speed. Statistical analysis confirmed a significant difference between pre-test and post-test results. The study concludes that integrating real-time speech recognition with preset response and question-selection features on a mobile platform provides an accessible, efficient, and inclusive communication tool that reduces barriers to communication and enhances social interaction. The system also supports offline functionality for broader accessibility in rural communities. Thus, this study recommends that developers and future researchers could develop a portable version of the system, such as a standalone device or a wearable, allowing users to use the speech-to-text system anytime, anywhere, without relying solely on a smartphone.
