Speech-to-text (STT) apps can be utilized to evaluate English language learners’ (ELL) pronunciation. The presentation will report on research findings, in which five different STT apps were tested for transcription accuracy. The STT accuracy rate was compared against pronunciation rating conducted by human raters, ELL English proficiency levels, and study-abroad experience. The findings also provide examples of the most mispronounced words by Japanese ELL within the context of experiment materials.
