2 is a configuration diagram of a public telephone according to the present invention, FIG. 3 is a detailed diagram of the voice generator of FIG. 1, and FIG. 4 is a flowchart showing a voice guidance process of the public telephone shown in FIG. As can be seen from FIG. 2, the public telephone of the present invention is a control unit 1, a coin selecting unit 2, a card reader unit 3, a display unit unit 4, an incoming and outgoing reproduction unit 5, and a dial. The transmission and call circuit unit 6, the handset 7, the voice generator 8, the speaker 9 and the power supply unit 10 are configured to be connected. The control unit 1 controls the overall operation of the public telephone by the built-in program, the coin selecting unit 2 outputs the information about the coin input to the control unit 1, and the card reader unit 3 uses the public telephone card. The data recorded in the control unit is read and output to the control unit 1, and the data from the control unit 1 is recorded on the public telephone card. The display device 4 displays the operation state and charge of the public telephone, the incoming call reproducing unit 5 reproduces the incoming signal, and the dial transmission and call circuit unit 6 dials to the trunk line under the control of the control unit 1. A signal is sent and the audio signal from the trunk line is output to the handset 7 side. The voice generating unit 8 generates, expands and outputs a voice signal to the speaker 9 in accordance with the data from the control unit 1, and the power supply unit 10 supplies power for operating the public telephone.

As shown in FIG. 2, the voice generator 8 is composed of a buffer 12, a voice synthesizer 13, a variable resistor VR and an amplifier 14. As shown in FIG. The buffer 12 receives the latch signal outputted from the controller 1 and a predetermined bit of data when the handset 7 is lifted. The latch signal from the controller 1 goes from the low state to the high state. When input, the strobe signal in the low state and the data received from the control unit 1 are output to the voice synthesis unit 13 side. The voice synthesizer 13 includes a memory device such as a ROM, stores various voice information, generates a corresponding voice according to the data from the buffer 12, and outputs the voice to the amplifier 14 through the variable resistor VR. do. The amplifier 14 amplifies the voice signal from the voice synthesizer 13 and outputs it to the speaker 9 to provide voice information to the user. The variable resistor VR adjusts the level of the voice signal applied from the voice synthesizer 13. The voice synthesis unit 13 also stores voice information on how to use and use a public telephone and voice information indicating which part has failed when a public telephone breakdown occurs. At the same time, it provides voice information and informs you of the broken part by voice to provide convenience for maintenance of the phone. The voice synthesizing unit 13 outputs a busy signal indicating the operation state to the control unit 1, and outputs a busy signal to the control unit 1 when outputting the voice signal to the amplifying unit 14. When the audio signal is not output, the busy signal is output to the control unit 1 side. Accordingly, the control unit 1 outputs data to the buffer 12 side only when the voice synthesis unit 13 does not output a voice signal.

Such public telephones operate in the order shown in FIG.

The controller 1 determines whether the handset 7 is off-hook (step 30), and if it is off-hook, determines whether there is a failure (step 31). Please insert "" (step 32). At this time, when the user inserts a pay phone card or coin, it is judged whether there is a pay phone card or coin amount (step 33), and if there is no card amount, a voice of "This card cannot be used" is output (step 33). 42) After discharging the public telephone card (step 43), the operation ends. In step 33, if there is a card amount or coin amount, a voice saying "Dial" is output (step 34), and it is determined whether a charging signal has arrived (step 35), and if a charging signal has arrived, "call". Outputs a voice (step 36), and judges whether the amount of money in the card or coin is greater than the currency unit amount (step 37). Output (step 38). Then, it is judged whether the handset 7 is on-hook (step 39), and if it is on-hook, the coin and public phone card use are distinguished (step 40). After the voice is output (step 42), the operation ends, and if coins are used, it is determined whether there is money returned (step 51). Outputs the voice and ends the operation. If the charging signal does not arrive in step 35, if the input amount is greater than the currency dominant amount in step 37, and if the handset is not hooked on in step 39, the process goes to step 35 to perform the next operation.

If there is a failure in step 31, identify which part is a failure (step 44), and if the coin selector 2 fails, output a voice of "Use only a card" (step 46), and then step 33 If the card reader unit 3 is out of order, it outputs the voice "Please use only coins" (step 45), and determines whether the input amount is larger than the currency unit amount (step 47), and the input amount is the currency. If it is larger than the unit price, a voice " dial " is output (step 48). After that, the international call is judged (step 49), and in the case of an international call, the voice of "International call is a card" is output (step 50).

As described above, the public telephone according to the present invention provides the user with voice using information and method for using the public telephone and the operation state of the public telephone by the voice generator 8, so that the public telephone user can use the public telephone.
