Acoustic Cues for the Perception of Initial /w, j, r, l/ in English

Abstract

The majority of the allophones of /w,j,r,l/ are voiced oral resonants, and the occurrence of voiceless fricative allophones of all four phonemes in the same phonetic environment, i.e., after a voiceless stop or fricative in the same syllable, whilst no doubt connected with their phonemic distribution, is an added mark or their coherence as a class.
