Abstract

PURPOSE:To prevent mischievous telephone from being called by registering a password in a password registration part in advance, and sending a call tone only when the password inputted by a caller in voice coincides with a registered password. CONSTITUTION:When an incoming signal arrives via a telephone line 1, an incoming detecting part 2 detects the incoming signal, and instructs the output of the voice set in advance to expedite to input the password to the caller to a voice synthesis part 3. When the caller vocalizes the password number from the telephone set on a caller side based on a voice instruction outputted from the voice synthesis part 3, the password number in inputted voice is inputted to a speech recognition part 4 via the telephone line 1, and a speech recognition processing is executed, and a recognition result is outputted to a comparison part 5. The comparison part 5 compares the recognition result outputted from the speech recognition part 4 with the password number registered in the password number registration part 6 in advance. When coincidence is obtained between them, an instruction to output the call tone is issued to a call signal output part 7. Also, when noncoincidence is obtained, the instruction to disconnect the line is issued to the incoming detecting part 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone set, and particularly to a telephone set for preventing prank calls.

[Conventional technology]

Conventionally, in order to prevent prank calls, telephones of this type either do not ring the ringing bell when receiving a call by using a switch or the like; Instead of ringing a bell, it was configured to flash a lamp.

[Problem to be solved by the invention]

In order to prevent prank calls, the above-mentioned conventional telephones either do not ring the ringing bell when receiving a call or ring the bell at 11. Since the lamp is blinked instead of θ, there is a drawback that if the switch is in the tamper-proof state, even if a legitimate call is received, it may not be possible to respond.

[Means to solve the problem]

The telephone of the present invention includes an incoming call detection section that detects an incoming signal from a telephone line, a voice synthesis section that outputs a voice prompting the input of a voice PIN number, and a voice synthesis section that outputs a voice prompting the input of the PIN number input via the telephone line. A voice recognition unit that recognizes a voice recognition unit, a PIN registration unit that registers a PIN number in advance, and a comparison between the recognition result of the input PIN number of the voice recognition unit and the PIN number registered in the PIN registration unit. and a calling signal output section that outputs a calling signal when the comparison results match.

〔Example〕

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

FIG. 1 is a functional block diagram showing one embodiment of the present invention.

In FIG. 1, the telephone of this embodiment includes an incoming call detection unit 2 that detects an incoming signal from a telephone line 1, a voice synthesis unit 3 that outputs a voice prompting the caller to enter a PIN number, and a a voice recognition unit 4 that recognizes a password by voice from a voice; a password registration unit 6 in which the password is registered in advance;
Comprising a comparison section that compares the input PIN number from the caller with the registered PIN number, a ringing signal output section 7 that outputs a ringing tone based on comparison in the comparison section 5, and a handset 8. are doing.

Next, the operation of this embodiment will be explained.

When an incoming signal arrives via the telephone line 1, the incoming call detection unit 2
detects the incoming call signal and instructs the voice synthesizer 3 to output a preset voice prompting the caller to input his/her personal identification number. Upon receiving the instruction, the voice synthesis section 3 sends a preset voice to the telephone line 1.

When the caller utters the PIN number from the caller's telephone according to the voice instruction output from the voice synthesis section 3, the input voice PIN number is input to the voice recognition section 4 via the telephone line 1, and the PIN number is input into the voice recognition section 4 via the telephone line 1. Recognition processing is executed, and the recognition result is output to the comparison unit 5. The comparison section 5 compares the recognition result output from the voice recognition section 4 with the password registered in advance in the password registration section 6, and if they match, outputs a calling signal to the calling signal output section 7. Instruct. If they do not match, the incoming call detection unit 2 is instructed to disconnect the line.

When the ringing signal output unit 7 receives a ringing signal output instruction from the comparison unit, it outputs a ringing tone until the handset 8 is off-hook or the caller hangs up.

〔Effect of the invention〕

As explained above, the present invention allows a PIN to be registered in the PIN registration section in advance, and a ring tone is sent out only when the PIN entered by the caller by voice matches the registered PIN. By doing so, the line will be disconnected without ringing for calls where the PIN number is not entered or the input PIN number does not match the registered PIN number, which can prevent prank calls. This has the effect of allowing you to answer incoming calls that are not prank calls.
