Hereinafter, the interconnection relationship and operation of these components will be described. An audible sound such as a broadcast sound or a chime sound output from the broadcast device 10 is received by the microphone 21. The output of the microphone 21 is connected to the amplifier 22, and the low frequency signal amplified by the amplifier 22 is supplied to the A / D converter 23 where it is converted into a digital signal. This digital signal is supplied to the signal processing unit 24.
[0018]
The chime sound broadcast from the broadcasting apparatus 10 has a predetermined regular pattern such as a sound having a constant frequency or a combination of sounds of a plurality of frequencies, whereas the chime sound from the automatic announcer 1 There is substantially no regularity in the audible sound (calling sound, contact broadcast sound, etc.) output from the message and the microphone 2. Using this property, the signal processing unit 24 determines whether or not the digital signal is a digital signal representing a chime sound according to the digital signal supplied from the A / D converter 23, and outputs the chime sound. A digital signal representing the audible sound is sent to the voice recognition unit 26.

Next, a case where the broadcasting apparatus 10 performs voice broadcasting such as in-house calling and contact broadcasting will be described. In this case, first, the broadcasting apparatus 10 first outputs a first chime sound that informs that such audio broadcasting is started. Therefore, the signal processing unit 24 of the portable terminal 20 determines that the digital signal from the A / D converter 23 represents the first chime sound, and gives this digital signal to the chime recognition unit 25. In response to this, the chime recognition unit 25 outputs a control signal, and applies this control signal to the character recognition unit 26, the voice-character conversion unit 27, the character output unit 28, the vibrator 29, and the light emitting unit 30. As a result, the character recognition unit 26, the voice-character conversion unit 27, and the character output unit 28 are put into operation, and the vibrator 29 vibrates, and the light emitting element of the light emitting unit 30 emits light. In this way, the person carrying the portable terminal 20 is notified that voice broadcasting such as in-house calling and contact broadcasting is started.
[0023]
Next, when sound representing contents such as in-house calling or communication broadcasting is input to the microphone 2, this sound is broadcast from the speaker 6 via the mixer unit 4 and the power amplifier 5. Then, the signal processing unit 24 determines that the digital signal from the A / D converter 23 is not a chime sound, and sends this digital signal to the voice recognition unit 26. The voice recognition unit 26 processes the digital signal from the signal processing unit 24 using a known voice recognition method such as pattern recognition, and converts the signal into a signal representing a series of words corresponding to the digital signal. Applied to the voice-character converter 27. The voice-character conversion unit 27 converts a signal representing a series of words from the voice recognition unit 26 into a character signal representing a corresponding character string, and supplies the character signal to the display 29 via the character output unit 28. It is displayed on the display 29. In this way, the contents of the audio broadcast such as the call and the contact broadcast are transmitted to the person carrying the mobile terminal 20.
[0024]
Following such audio broadcasting, the broadcast device 10 outputs a second chime sound that informs the end of the message broadcast, so that the signal processing unit 24 indicates that the digital signal from the A / D converter 23 represents the second chime sound. Determination is made and this digital signal is given to the chime recognition unit 25. In response to this, the chime recognition unit 25 outputs a control signal, and applies this control signal to the character recognition unit 26, the voice-character conversion unit 27, the character output unit 28, the vibrator 29, and the light emitting unit 30. As a result, the character recognition unit 26 and the voice-to-character conversion unit 27 are initialized, and the character output unit 28 and the display unit 31 stop their operations and cause the display unit 31 to hold the display contents and vibrate the vibrator 29. The light emitting element of the light emitting unit 30 emits light. In this way, the end of the message broadcast is notified to the carrier.
[0025]
Although one embodiment of the notification system according to the present invention has been described above, the present invention is not limited to this.

Accordingly, the mobile telephone may be used as the mobile terminal 20.
[0026]
Further, in this embodiment, the start and end of the broadcast are each notified by a chime sound. However, the chime that notifies the end of the broadcast can be obtained by configuring the broadcast device 10 to end the broadcast after a predetermined time has elapsed. It may be abbreviated as “sound”, and a chime sound that informs the start of broadcasting and the broadcast content may be broadcast. Furthermore, instead of the chime sound, a signal outside the audible band that can be received by the microphone 21 can be used as the notification sound. In this case, a notification sound recognition unit is used instead of the chime recognition unit 25.
