Acoustic analyses were undertaken to explore the durational characteristics of the fricatives [f,θ,s,v,F,z] as cues to initial consonant voicing in English. Based on reports on the perception of voiced–voiceless fricatives, it was expected that there would be clear‐cut duration differences distinguishing voiced and voiceless fricatives. Preliminary results for three speakers indicate that, although differences emerged in the overall mean duration of voiced and voiceless fricatives, contrary to expectations, there was a great deal of overlap in the duration distribution of voiced and voiceless fricative tokens. Further research is needed to examine the role of duration as a cue to syllable‐initial fricative consonant voicing in English.
