Abstract
The authors had reported the phonogram that presented relationships between pitches and intensites of the voice dimensionally like an audiogram. However, in order to write a phonogram of a patient with hoarseness. It was possible to record automatically the intensities by a sound level recorder, but the pitches had to be determined subjectively with piano. This seemed to be a cause for the phonogram not to become popular. In this paper, we tried to create a phonometer, by which the phonogram was recorded full-automatically. The measurements of pitch and intensity about a speech range, changes of pitches and intensities at the voice register, evaluations of those factors on the singing a song or the reading asentense, etc. were figured by phonogram with this instrument.
This phonometer seems to be utilized for a clinical examinations of various voice disorders.
