FIG. 1 is a block diagram showing a system of a voice response telephone according to an embodiment of the present invention, and FIG. 2 is a flowchart showing a flow of operations.

In FIG. 1, a telephone circuit 1 is connected to a telephone line and has a function of making and receiving a telephone call. An electric signal sent from the telephone line is output as a voice signal and a transmission voice signal is output to the telephone line. It has a function of converting into an electric signal for performing. The dial input switch circuit 4 is a circuit for inputting a destination telephone number when a telephone call is made. The telephone number signal input here is passed to the telephone circuit 1 via the central processing circuit 6,
Convert to tone signal or pulse signal in telephone circuit,
Output signal to telephone line. The ringer circuit 5 outputs a bell sound to indicate an incoming call when a call is received, and the handset circuit 2 inputs / outputs a voice signal during a call. The handset microphone 21 and the handset speaker 2 are used.
It consists of two. The hook switch 3 is a switch for switching connection / non-connection with a telephone line to set the telephone to a callable state, and connection with the telephone line is possible by separating the handset from the telephone body.
The microphone 7 and the speaker 8 are configured so that a call can be made without turning off the handset from the telephone body by turning on the monitor switch 41 included in the dial input switch circuit 4. Voice recognition circuit 9
Has a function of converting an analog voice signal input from the microphone 7 into a digital signal, comparing the analog voice signal with a voice signal registered in the storage device 10 in advance, and passing the comparison result to the central processing circuit 6. The central processing circuit 6 is a circuit capable of controlling the telephone circuit 1, the handset circuit 2, the hook switch 3, the dial input switch circuit 4, the ringer circuit 5, the microphone 7, the speaker 8 and the voice recognition circuit 9, and is of the present embodiment. It controls the entire telephone system.

The voice response telephone of this embodiment constructed as described above operates according to the flow chart shown in FIG. First, when the telephone circuit 1 receives a call signal of a telephone from a telephone line as an incoming call processing, it sends a signal notifying the incoming call to the central processing circuit 6, and the central processing circuit 6 rings the ringer circuit 5 to notify the user of the telephone. A signal for starting the monitoring of the voice signal is sent to the voice recognition circuit 9 while notifying that the call has been received, and the microphone 7 monitors the external voice signal. When the telephone user utters a voice signal indicating that he / she wants to talk, the voice signal is sent to the voice recognition circuit 9 through the microphone 7, and the voice recognition circuit 9 stores the input voice signal in the storage device. The central processing circuit 6 is instructed to carry out an incoming call process (in this case, set to speakerphone and line connection) if it is the same signal within the allowable range, compared with the voice signal registered in 10. send. The central processing circuit 6 issues a command to the telephone circuit 1 to establish a line connection, and at the same time sets the speakerphone call-enabled state. As a result, it is possible to provide a voice response telephone capable of switching the telephone to the call-enabled state even in the situation where the hand cannot be released when receiving a telephone call.

In the above-mentioned configuration, the contents of setting the speakerphone as the incoming call processing and connecting the line are set. However, by registering the stop of the ringer circuit 5 in the storage device 10 as the incoming call processing, it is possible to make a call without answering the call. It is possible to provide a voice response telephone capable of performing an incoming call process for stopping only the noisy ringer when waiting for the called party to disconnect.

When a voice response telephone with an answering machine function is used, by registering the answering machine corresponding to the answering machine in the storage device 10 as an incoming call processing, when the person who does not want to answer the call but wants to know who is calling. It is possible to provide a voice response telephone capable of answering the user. Although FIG. 2 shows the flow of switching to the call enabled state by the voice signal, a plurality of voices for incoming call processing are registered in the storage device 10,
By setting different incoming call processing for each, it is possible to provide a multifunctional voice response telephone which allows the telephone user to perform desired incoming call processing, and the flow is shown in FIG.

The storage device 10 is a readable / writable IC memory (RAM) and stores voice signals corresponding to a plurality of incoming calls. For example, the audio signal "a"
Register the contents of connecting the telephone line and switching to the speaker, stopping the ringer for the voice signal "i", and connecting the telephone line for the voice signal "u" and answering.
When a telephone call comes in, the telephone user says "A" to connect the telephone line to switch to the speakerphone, say "I" to stop the ringer, and say "U" to connect the telephone line and leave. It is possible to provide a voice response telephone which enables the user of the telephone to perform the incoming call processing desired by him / her even in a situation where he / she cannot answer the telephone such as making a response.

Although the storage device 10 is an IC memory in the above configuration, a storage device such as a magnetic storage device or an optical storage device may be used, and the registered voice is set at the time of manufacturing the voice response telephone. Alternatively, the telephone user may register in the voice of the telephone user.

In FIG. 2 and FIG. 3, since the voice recognition signal is monitored all the time after the incoming call signal is received, the monitoring is performed even when the ringer is ringing, and the ringer sound is the voice recognition signal. It becomes noise and it becomes difficult to perform accurate voice recognition. Therefore, in order to remove the ringer noise, the voice recognition rate can be increased by monitoring the voice recognition signal as shown in FIG. 4 only when the ringer is not ringing. However, if monitoring is performed only when the ringer is not ringing, the monitoring time will be shortened.Therefore, by shortening the ringing time, the effect of the ringer sound can be removed and long-term monitoring can be performed. It is possible to increase the recognition rate of the recognition signal.

Furthermore, when receiving a voice recognition signal for performing these incoming call processing and performing registered incoming call processing,
It is possible to provide a voice response telephone capable of notifying the telephone user of the incoming call processing by changing the sound of the ringer or outputting the content of the incoming call processing from the speaker.
