ABSTRACT

In this paper, from the point of view of speech signal processing as an engineering application, the comparative study of the Pyongyang and Seoul dialects is performed. In special, the affricates "ㅈ, ㅉ, ㅊ", which would have different phonetic values between Pyongyang and Seoul dialects, are focused and compared. For these consonants, the speech parameters such as the spectrogram, pitch, and Formant frequencies are extracted (measured) and the differences in their phonetic values of these two regions have been compared. It is confirmed that for these consonants, the Pyongyang dialects have higher energy cohesion than the Seoul dialects, and the distribution of Formant frequency was well distinguished. With the vowel study of Pyongyang dialect, which was carried out with phonological or experimental phonological methods, this paper presents the study of consonants in Pyongyang dialect by using the speech signal parameters. In this paper, a method is proposed for verifying linguistic investigations and experimental phonetic results by using signal processing.
