ABSTRACT

The present study analyzed Korean learners’ production of English /z/-/ʤ/ at two different proficiency levels (beginners and advanced) according to the manner and place of articulation. The manner of articulation was examined by the waveform and spectrogram analyses. The place of articulation was explored by referring to the peak amplitude frequency of the frication noise. The use of both the manner and place of articulation linearly increased according to the proficiency level of Korean speakers. The correct use of manner of articulation did not always lead to the correct use of place of articulation and vice versa. Among the error patterns, the pattern of the correct use of place of articulation and the incorrect use of manner articulation was more prevalently attested than the reverse pattern. In the production of English /z/-/ʤ/, Korean learners more frequently used the place of articulation than the manner of articulation in their error patterns.
