Title: Radio telephone set
Inventor: YOSHIDA HIROKI
IPC: H04W76/00
Filed: 1989-11-22
Abstract: PURPOSE:To attain a dialing function with simple operation by voice recognition to each telephone number even when two telephone numbers or over are always set to an opposite party by dialing other telephone number when a predetermined time elapses. CONSTITUTION:When a key is depressed by a key section, the mode is set to the recognition setting mode and a registered voice such as 'henry' is uttered to a microphone. The inputted voice signal is fed to a voice recognition LSI 350b and recognized therein and a recognition result storage memory 350c makes collation and when the result of recognition is extracted, a relevant telephone number is extracted from a telephone number storage memory 350d. In this case, when two telephone numbers are made correspondent, the telephone number registered initially is extracted and the content of recording is extracted by a voice recording IC 350a and outputted from a speaker. When a prescribed time elapses but the opposite party is still busy, the 2nd telephone number is used for dialing automatically. Thus, even when two telephone numbers or over are set to an opposite party, the dialing function by voice recognition is realized with a simple operation.
