This study examines the spectral characteristics of English voiceless fricatives depending on the manner and place of articulation, gender, age, the post-fricative vowel height, and the location in a word based on the Buckeye Corpus of Spontaneous American English Speech. The acoustic analysis results indicate that fricative duration, the center of gravity (COG), variance and skewness play a role in distinguishing all English voiceless fricative articulation places, despite variation in gender, age, the location in a word and the post-fricative vowel height. These acoustic parameters distinguished the sibilant /s, ∫/ from the non-sibilant fricatives /f, Ɵ/, and alveolar /s/ from palate-alveolar /∫/, labiodental /f/ from interdental /Ɵ/: fricative duration, COG, and variance of the sibilant fricatives were significantly longer/higher than those of the non-sibilant fricatives. Skewness was high for the non-sibilant fricatives and low for the sibilants. (Korea Polytechnic College)
