Equipment, 15 is the phone number! A line connecting device 13 connected to the microphone 1B is a changeover switch that switches the electrical signal from the microphone 12 to the voice recognition device 14 and the line connecting device 15. Next, the operation of the voice recognition telephone according to this invention will be explained. First, when the speaker picks up the receiver 1, the changeover switch 13 connects the voice signal from the microphone 12 to the voice recognition device 14, and the voice recognition device 14 enters a state of waiting for input. In this state, when the speaker pronounces the digits of the telephone number of the destination, the voice recognition device 14 interprets the digits through the microphone 12 and displays the contents on the character display 9. When the speaker looks at the content displayed on the character display 9 and determines that the content has been correctly recognized, he presses the confirmation switch 10, and the signal becomes a voice! ! ! The information is transmitted to the recognition device 14. Thereafter, the speech recognition device 14 switches the changeover switch 13 to the line connection device 215 side, and sends the recognized content to the line connection device 15. Then, the line connection device 15 transfers the received contents to the telephone line 1.
Send to 8. This line connection operation is performed by push-button telephones, which are currently widely used. By the way, if the speaker determines that the content displayed on the character display 9 is different from the content input by voice, he or she presses the cancel switch 1. With this, voice! ! identification device 14
cancels the content that had been accepted up to that point, erases the display content displayed on the character display 9, and returns to the input waiting state. Furthermore, if the speaker wants to try to make a call again, he or she can simply say the other party's phone number anew, and if he or she wants to end the call, he or she can simply hang up the receiver. In the above embodiment, the telephone number of the other party to be called is directly input by voice, but the voice recognition device 14 or the line connection device Wl5
It has a storage device attached to it, and if the data for this device is stored, it is easy to have a speed dial function that retrieves the corresponding telephone number from the storage device and connects the line by uttering a short keyword. Further, as the character display device 9, electronic display elements widely used at present, such as liquid crystals, LEDs, and fluorescent display tubes, can be used. Further, although the confirm switch 10 and the cancel switch 11 are arranged on the side of the handset 1, they may be provided at a position where they are easy to operate, such as on the transmitting/receiving side of the handset. [Effects of the Invention] As explained above, according to the present invention, the first switch mechanism has a character display that displays the content recognized by the voice recognition device, and activates the line connection operation in accordance with the recognized content. Since the handset is equipped with a second switch mechanism that cancels the recognized content, the voice input content can be displayed on the character display, allowing for prompt and accurate confirmation. Furthermore, the VA connection operation is simple and can faithfully carry out the speaker's intention.
