초록
The paper describes methods of conducting vowel analysis from a large-scale corpus with the aids of forced alignment andoptimal formant ceiling methods. ‘Read Style Corpus of Standard Korean’ is used for building the forced alignment systemand a subset of the corpus for the processing and extraction of features for vowel analysis based on optimal formant ceiling. The results of the vowel analysis are reliable and comparable to the results obtained using traditional analytical methods. Thefindings indicate that the methods adopted for the analysis can be extended and be used for more fine-grained analysiswithout time-consuming manual labeling without losing accuracy and reliability.
