A detailed spectral analysis of an extensive fricative corpus for two subjects was performed to attempt to specify further the acoustic differences between the front fricatives, and thereby illuminate the production mechanisms involved. Differences were found between the ensemble-averaged spectra mid-fricatives; these vary with vowel context. Differences are least apparent, and spectra are most flat, in the [a-a] context; mechanical model results indicate this may be due to effect of lip shape on a very short front cavity.
