This paper aims to examine the durational characteristics of Korean Lombard speech using speech data, which consist of 500 Lombard words and 500 normal words of 10 speakers (5 males and 5 females). Each word was segmented and labeled manually and the duration of each segment and each word was extracted for comparison. The durational change of Lombard speech in comparison with normal speech was analyzed using a statistical method. The results show that durational characteristics of Korean Lombard speech mostly correspond to the results reported in previous research. The duration of words in Lombard speech is increased in comparison with normal speech, and the average unvoiced consonantal duration is decreased while the average vocalic duration is increased. Female speakers show a stronger tendency to lengthen the duration in Lombard speech, but the difference between females and males was not statistically significant. Finally, this study also shows that the speakers of Lombard speech could be classified according to their different duration rates, which demonstrates speaker dependent characteristics.
