The literature contains numerous studies including computer algorithms to evaluate pronunciation level of Japanese speakers of English. However, up to now, most research has been based on English native speakers' (NSs’) accuracy perceptions. Japanese NSs’ perception of correct pronunciation has been relatively overlooked. Relevant questions are: “W...
