Abstract

PURPOSE:To eliminate unnecessary dealing to a telephone call, by automatically compar ing the electric voice signal of the opposite side with electric voice signals of plural acquaintances recorded in advance and, only when the received electric voice signal coincides with one of the recorded voice signals, informing the listener of the fact. CONSTITUTION:A listener manually connects an enable switch 102 to B side when be senses the ringing sound of a bell 109. Voice input signals are sent to a voice comparing section 111 through a received voice amplifier 103. Recorded voice signals which are recorded in a voice recording section 110 in advance are sent to the section 111 and compared with the received voice signal which is the voice signal of one of many and unspecified persons in the voice comparing section 111. When the received voice signal does not coincide with any one of the recorded voice signals, an enable switch automatically controlling section 112 forcibly cuts off the enable switch 102 so as to disconnect the call from the calling subscriber and, at the same time, connects the telephone line 101 to the bell 109 side. When the inputted voice signal coincides with one of the recorded voice signals, the section 112 sends a notice control signal to an indicator 113 and actuates the indicator 113. After confirming the notice of the indicator 113, the listener listens to the inputted voice signals through a loudspeaker 104 after he depresses a receiver hook switch 114.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block circuit diagram showing an embodiment of the present invention, in which a bell ringing signal that enters the telephone via the telephone port m tot is sent to the enable switch 102, which is normally connected to the A side. The bell 109 is rung via the terminal. ! !
The receiver who senses the IS sound manually connects the enable switch 102 to the B side. This enable switch 102
can be operated under either manual or automatic control, but priority is given to control when a switch changeover control signal is input from the enable switch automatic control section 112, which will be described later.

The above-mentioned enable switch 102 receives the input bell ringing signal as an input to the local telephone and the receiving audio amplifier 10.
3, the output signal from the transmitting audio amplifier 105 as an output from the own telephone, and the output signal from the dial pulse generator 106. Audio input signals transmitted from an unspecified number of parties are sent to the audio comparison unit 1 via the receiving audio amplifier 103.
Sent to 11. On the other hand, the recording unit 110 records the voices of multiple acquaintances.
If you want to record on the voice recording section 110, turn on the voice recording changeover switch 115, introduce the voice signals of a plurality of acquaintances outputted through the Tt telephone line and the receiving voice amplifier 103 into the voice recording section 110, and record them in advance. This audio recording unit 11 records
