Japanese vowel devoicing typically occurs on a high vowel between voiceless consonants. Such devoicing is regular and complete. By contrast, atypically there are devoicing cases of non-high vowels and in non-devoicing environments, which are irregular and gradient. For these varying manifestations, some physiological studies demonstrated distinct muscle activities and glottal spread patterns. Also there is a phonological account that postulates distinct feature specifications for those types. This study attempts to incorporate these postulations in the C/D model to generate different manifestations, and it further discusses the potential of the model to map phonological specifications to their variable phonetic output.
