The purpose of this study is to develop a system which supports Japanese learners’ speaking practice utilizing Text-to-Speech (TTS) technology and to investigate how they practice with the system on the basis of learning log data. The characteristics of the system are (i) they can choose words, chunks, sentences, or passage which they prefer to practice at any time; and (ii) the system utilizes a common TTS engine which enables learners to access through Internet. The system stored all the log data on participants’ behaviors; every click of words, chunks, sentences, and passages with time stamps. First, this paper demonstrates how the system visualizes each learner’s learning behavior. The seven-week experimental study shows that there are three types of group observed in the analysis regardless of their proficiency levels. In addition, some participants change their learning behavior depending on the materials.
