This study examined acoustic characteristics of 900 CV syllables produced by five English native speakers. Those target syllables were produced between the syllable /ba/ twenty times. The syllables were segmented and normalized by the maximum intensity value of each syllable and were divided into consonant or vowel sections by a few visible acoustic criteria. Intensity values were collected at 100 relative time points per syllable. Also, cumulative intensity values and consonant and vowel durations along with the ratio of a consonant to each syllable were measured using Praat scripts. Results showed as follows: Firstly, the consonantal section amounted to a quarter of the syllable in terms of both the cumulative intensity and duration. Secondly, the consonantal ratio by the cumulative intensity was similar to that by the duration. Finally, the sum of the cumulative intensity values in each syllable partially coincided with the consonant order by the current sonority scale. Further studies would be desirable on more reliable acoustical measurements and sophisticated perceptual experiments on the English syllables.
