Seo, YoonJeong. 2021. A study of the variation of Korean lateralization in /l-n/ sequences.  Studies  in  Phonetics,  Phonology  and  Morphology  27.1.  27-52. This study aimed to investigate the realization of Korean lateralization in /l-n/ sequences. In previous studies, progressive lateralization has been considered a compulsory phonological phenomenon in Korean, and has not attracted much attention. However, in actual speakers’ speech, non-assimilation patterns are observed in /l-n/ sequences. A reading task was conducted with 20 Korean speakers in their 20s in order to acquire the realization of /l-n/ sequences. The realization of progressive lateralization was  shown  to  differ  depending  on  individual  speakers  and  experimental words/phrases. The greater the morphological boundary between /l/ and /n/, the less likely was lateralization. In addition, in principle, lateralization is realized even if a phonological  phrase  is  located  internal  to  an  /l-n/  sequence,  but  more  non- assimilation patterns have been observed in tokens where phonological boundaries occurred. Gender and speech rates also influence the realization of lateralization. Male speakers lateralize /l-n/ sequences more stably than female speakers. Moreover, the rate of lateralization increased when the speech was faster. 

Keywords: lateralization, /l-n/ sequences, variation
