The author developed the new system of discrimination test and the results of test were processed by digital computer. The processing was based on the acoustical feature of the speech sounds.
The data of the normal hearing and the deaf children (6-10 years old, mostly sensori-neural hearing loss and partially mixed hearing loss) were analysed. The following results were obtained.
1. It was found that the order of articulation performance among the consonant groups had a relation with the type of audiogram and its tendency depended on the acoustical feature of speech sounds.
It was thought that the order of articulation performance could be used effectively as the criterion of hearing aid fitting and auditory trainning program.
2. For the full automatic system of the speech discrimination test, it is necessary to develop a method that any subjects can easily respond.
3. This new system can save many manpowers on making confusion matrix etc., and the well formed pictures can be displayed.
