This paper investigates whether listeners perceive a different level of politeness when the duration of the Korean sentence-final auxiliary particle '-yo' is varied. A total of 10 Korean sentences were manipulated by lengthening and shortening '-yo' by 10%, 20%, and 30%. The participants included native Korean speakers and Chinese and Japanese learners of Korean (n=10, respectively). They were asked to rate the level of politeness of the stimuli on a 9-point scale. It was found that Korean listeners perceived decreased politeness as the duration of '-yo' was shortened and increased politeness as it was lengthened. However, Chinese and Japanese listeners did not perceive a different level of politeness from the manipulated sentences. This finding suggests that it is important to teach L2 speakers that the duration of the auxiliary particle '-yo' plays a role in Korean listeners' perception of politeness.
