Abstract
A call other than a conversion partner call and various sounds are detected by input audio signals from plural microphones without deteriorating a voice recognition precision. A hearing aid apparatus according to the present invention corrects a frequency characteristic of the call voice other than the conversation partner voice based on an arrival direction of the call voice other than the conversation partner voice, which is estimated based on the audio signal converted by the plural microphones, checks a call word standard pattern representing features of a phoneme and a syllabic sound based on other voice data picked up by using the microphones having one characteristic against a call voice other than the conversation partner voice in which the frequency characteristic is corrected by the frequency characteristic correction processing unit to determine whether the call voice is a call word, and forms a directivity in the direction other than the arrival direction of the voice of the conversation partner. Then, the hearing aid apparatus according to the present invention corrects the frequency characteristic of the call voice other than the conversation partner voice so as to provide the same characteristic as that of the microphones at the time of creating the audio standard pattern.
