This paper is to find out phonetic evidence to argue sequences of /s/ and a stop consonant occurring in the onset of English form a single unit. An acoustic experiment measuring duration of singleton consonant onsets and bi-consonantal onsets was conducted with various null and alternative hypothesis to check if the sequences of /s/+stop in the onset are as long as one segment or two. The result shows that the consonant clusters beginning with /s/ is as long as one consonant, supporting the phonological argument that /s/ and the following stop sound are not consonant clusters but a single complex sound.
