The purpose of this study is to improve the pronunciation of English, something that Japanese people have difficulty with. Therefore, this study focuses on the Japanese pronunciation of English and investigates the movement of the muscles around the oral cavity in speaking English using EMG measurement. We investigated the pronunciation of vowels, which is important in English pronunciation, and measured English words that containing short and long vowels among single vowels. In order to investigate whether it is possible to identify single vowels from the acquired EMG signals, we used root-mean-square analysis, which quantifies the graph, and wavelet analysis, which can analyze the signal into frequency and time components. Currently, we haven't got enough clear distinction between single vowels, yet we will seek further evaluation methods for identifying vowels.
