The object of the present work is to obtain quantitative knowledge about the physical nature of the accent in Japanese.
The sounds of spoken words were recorded by means of an electrical arrangement (Fig. 2), consisting of a condensermicrophone, a several-stage vacuum tube valve amplifier and a Duddell high-frequency oscillograph. Highly stretched sheet of duralumin, 0.02mm. thick, was employed as the membrane of the microphone (Fig. I), and resistance-capacity couplings were used throughout in the amplifier. The recording apparatus is, therefore, believed to be the best now available, giving the most faithful record of sound.
Records were obtained for two men and two women, for several mono-andbl-syllablee words, and the change in the pitch of the sound in the word was thus accurately determined from the oscillograph records. Several typical records thus obtained, are reproduced in the annexed photographs, and records of vowels are also reproduced for the sake of reference. Finally, the accent in the intensity of the sound is also discussed.
