摘要

This paper presents a study of devoicing of European Portuguese fricatives. Two devoicing criteria (a manual criterion and a criterion based on the ratio of variances of the laryngograph signal during the VF transition and during the fricative) were used to classify the examples into two or three categories. The results of the automatic and manual measures of devoicing are compared, and an explanation for observed misclassifications is presented. Devoicing occurs extensively in Portuguese; results are compared to those for English.
