To study the speech sounds on the ground of timbre is of the utmost importance. Timbre aspect is, in this sense, the starting point of our study and at the same time the finishing one. In the classification of vowel-sound timbres for example, it is quite indispensable from the timbre aspect that the two elements, phoneme and voice, be made clear. In the timbre theory, phoneme classification is relatively easy, because a great many studies have already been made in this field. But the problem of voice classification would be much more difficult, because there is very little that has been done concerning this domain of research. It is essential that we distinguish most clearly these two elements, phoneme and voice, and that we do not confuse them. Distinction between phoneme and voice would lead us very far and bring us no advance. The consideration of dualism of quality is very serviceable for the general treatment of a problem such as “classification of timbres in broad and wide meaning”. In order to describe the timbre-quality of musical instrument sounds for instance, the phoneme-aspect based upon human vowel is of some value. But for the quality estimation or quality rating of musical instruments based upon auditory preference or acoustical taste, the voice-aspect of human sounds is far more important and effective than the phoneme one. In this paper we tried to insist on this point of view by citing exclusively the example of violin sounds.}, pages = {364--374}, title = {Memoir on the problem of description and classification of timbre in general}, volume = {13}, year = {1962} }
