Abstract

본 발명은 현재 선택하는 전화 번호가 음성으로 들리도록 하기에 적합한 전화기의 음성 발생 장치에 관한 것으로, 종래의 기술에 있어서 사용자의 키조작에 따른 반향음을 그 사용자가 구별하기 어렵기 때문에 현재 정확한 키조작을 하고 있는지 여부를 판단하기가 불가능하였으나, 본 발명에서는 사용자가 현재 키 조작 상태를 명확히 알면서 키를 조작할 수 있도록 함으로써 키 조작 오류가 없으므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a voice generating device of a telephone which is suitable for allowing the telephone number to be selected at present to be heard by voice. In the related art, the user is unable to distinguish the echo sound according to the user's key operation. Although it is impossible to determine whether or not the operation is performed, the present invention can improve the above-described drawbacks because there is no key operation error by allowing the user to operate the key while clearly knowing the current key operation state.
