Abstract
The analysis of acoustic correlates of devoiced vowels produced by young native Japanese speakers is presented. In addition to gradient amounts of voicing seen in vowels undergoing devoicing, gradient amounts of fricativization can be observed, supporting an analysis of devoicing in Japanese as gestural overlap of both glottal gesture and oral stricture. Specifically, the surfacing of voiceless consonant‐devoiced vowel sites as voiceless fricatives, evidenced by high‐frequency frication in spectrograms and a significantly higher number of zero crossings, will be discussed, as will the interplay between devoicing and fricativization in the data set. Analysis of the formant frequency information at the vowel sites, preserved in the frication and allowing the perception of the original vowels even in the face of heavy loss of vocality, is also presented.
