"Singing" is one of the most important and popular artistic human activities. The purpose of this research is to develop a mechanical Singer Robot with artificial larynx. We have already developed a singer robot that can generate Japanese 5 vowels [a], [i], [u], [e], and [o], and it can change the voice pitch by manipulating the artificial vocal cord. The robot has become to be able to generate some of the Japanese consonants such as "ba" and "pa". In this paper, the investigation of the influence that the pitch control mechanism gives to the consonant utterance is described. To expand the consonant that was able to be uttered, the vocal chords vibration control mechanism that switched the voiced sound to the voiceless sound was made.
