Development and usability testing of a speech-technology based face-to-face mobile communication application for people with hearing impairments

Abstract

Objectives: The purpose of this study was to identify difficulties and support requirements experienced by people with hearing impairments in daily communication with their hearing communication partner, to develop a speech-technology based face-to-face mobile communication application based on their needs, and to evaluate the necessity and validity, ease of use, satisfaction, and utilization of the application by conducting usability tests. Methods: This study investigated the functionality of the mobile communication application for people with hearing impairments by examining current mobile communication applications and by reviewing previous literature. We then developed a speech-technology based face-to-face mobile communication application reflecting the required functions. In order to evaluate the usability of the face-to-face mobile communication application, usability tests comprised of scenarios and survey questionnaires were conducted with 25 people with hearing impairments. Results: The results of this study showed the usability of the developed speech-technology based face-to-face mobile communication application was positive (above 4 on the 5-point Likert scale) in terms of feasibility, user-friendliness, satisfaction, and utilization. Conclusion: It is expected that the developed mobile communication application will help improve social participation and quality of life for people with hearing impairments. It is also expected that the development of various domestic mobile communication devices for people with hearing impairments or language disorders will be promoted.
