音声言語療法学生向けの音声文字起こしトレーニングのeラーニング

Using a web-based tool as a supplement to classroom training may provide immediate feedback and alleviate teacher workload. The present study employed the web-based Phonetic Transcription Practice (PTP) system to train phonetic transcription skills in Mandarin-speaking speech-language therapy students and examined which aspects of students' learning progress contributed most to their post-test performance. In a pretest-posttest design, students majoring in audiology and speech-language therapy in Taiwan (n = 36) participated in a 12-week online Mandarin transcription training program using PTP. Four dimensions were used to assess students' transcription skills: correctness judgments, syllable structure analyses, error-type classification, and single-word transcriptions. Learning progress was evaluated using multiple regression analysis to assess the effects of training weeks and speech type on transcription accuracy. Participants also completed a survey about their learning experience. The results showed that the cohort improved significantly across the four transcription dimensions after the 12-week training program. Both average submission frequency (i.e., the number of times assignments were submitted per week) and accuracy effectively predicted post-test performance in error judgment and error-type classification. Additionally, the learning curve for typical speech transcription was significantly steeper than for disordered speech, highlighting the greater challenge the latter presents. Taken together, PTP is the first Mandarin transcription training system that includes typical and disordered speech for training syllable structure analysis and error-type classification with immediate feedback. Using this e-learning system, the study mapped students' transcription practice and learning progress and identified process features linked to post-test performance, offering insights for structuring transcription training in SLP education.
