抄録
The 2-dimensional pitch-intensity indicator is an apparatus for use by the deaf who train to control vocal chord vibration efficiently by sustained utterances. By means of this indicator, the pitch (fundamental frequency) signal is extracted using an improved "Gruenz-type" pitch detector in which the time constant of integration is varied automatically to fit the speech signal. Pitch and intensity signals are displayed on a 12" CRT screen. The training was conducted for about 5 weeks with 8 deaf children (7-9 years old) by a teacher of the school for the deaf. The results of the analysis of the training effect are as follows: (1) The utterances of the deaf children trained with the indicator are superior in stability of pitch and intensity to those of the deaf children without it. (2) Three months after the end of training, it was shown that the utterances of the deaf children the indicator became more stable than at the end of training. These results can also be verified by listening to the utterances of the children.
