Audio content is an effective way to support language learning, but currently there are not many Japanese language learning materials that offer audio content. One of the reasons for this is the high cost of voice recording and editing. Therefore, the authors attempted to add voice content to learning material for technical terms of care specialties using the VOICEPEAK synthetic speech software. As a result, it was found that it was possible to create voice content at a practical level while keeping creation costs low. The use of synthetic speech for Japanese language learning materials is a realistic option.
