Abstract
AbstractThe expired air used in the generation of speech is released with the speech and produces a unipolar pressure variation of the air. This pressure fluctuation is considered as a kind of speech and is called the dc component. the dc component is composed of the expired air affected by the articulation organ and is considered to contain the articulation information.This study aims at the use of the dc component in the utterance training. Using the variable reactance pressure sensor, the relation between the dc component of the stop and the articulation is examined. the following results are revealed.The dc component of the stop is radiated from the mouth with a sharp directivity specific to each stop. the dc component of the stop is a sharp triangular pulse wave, with the peak value (i.e., the maximum of dc component) and the peak position related to the articulation position and the utterance intensity. In order to learn the utterance of the stop, it is required to master the correct articulation, especially the articulation position, but it is fairly difficult to determine the articulation position from the speech wave. On the other hand, it is easy to estimate the articulation position from the peak value and the peak position of the triangular pulse of the dc component, together with the direction of radiation of the dc component. In other words, it is seen that the dc component can be utilized in the utterance training.
