| Abstract(in English) | It has been said that auditory feedback is effective for rehabilitation of aphasia. This feedback consists of a speech signal that is produced by an aphasic patient and a therapist with a frequency component from 300 to 3000Hz. This feedback is called "Discontinuity effect in frequency". However, there is not enough evidence or verification for the efficacy of the rehabilitation method regarding what factors are essential. In this study, in order to verify the efficacy of "Discontinuity effect in frequency", we made a device with a DSP that enabled us to give feedback to the rpatients themselves while cutting off various frequency component of aphasic patients' voices. As a result, we found one case in which an aphasic patient was able to vocalize easily through the aid of feedback of a frequency component "F2". We also found that the patient could not discriminate his voice easily through the aid of this feedback. Additionally, we could not prove the efficacy cutting off feedback of a frequency component from 300 to 3000Hz. Finally in some cases, aphasic patients could not even vocalize with the feedback voices. |
