Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device that automatically performs a dialing operation based on voice recognition or enters a hands-free talking state when the approach of a human body is detected.

0002

2. Description of the Related Art Conventional telephone devices are equipped with a handset for making calls and a dialer such as a numeric keypad for dialing a telephone number. However, such telephone devices are provided with a light source that illuminates the numeric keypad buttons from the back side, considering that they are used in dark places.

0003

[Problems to be Solved by the Invention] However, when using such a conventional telephone device in a dark place, it is necessary to pick up the handset and go on-hook, and it is difficult to locate the telephone loudspeaker button. Dial dialing requires picking up the handset and then pressing a dial button, which is troublesome, and there are also problems in that talking for a long time while holding the handset can be tiring.

[0004]The present invention has been devised to solve these conventional problems.When the approach of a human body is detected, a dialing operation is performed using voice recognition. The purpose of the present invention is to provide a convenient telephone device that enters a hands-free talking state when detecting the following.

[0005]

[Means for Solving the Problems] A voice input means for inputting a voice signal, a voice recognition means for recognizing the input voice, and a dial number sending means for transmitting a dial number based on the recognition result of the voice recognition means. , a transmission/reception switching circuit that compares the levels of transmission and reception to switch between transmission and reception; human body detection means that detects the approach of a human body and outputs a detection signal; /
Alternatively, it is provided with a control means for controlling the operation of the transmitting/receiving switching circuit.

[0006]

[Function] When a user is detected by the human body detection means of the telephone device, the voice recognition means automatically operates to send a voice dial, and the transmitting/receiving switching circuit operates to switch the handset to the receiver. You can make hands-free calls without having to pick up the phone.

[0007]

[Embodiment] As shown in Fig. 1, there is a central office line connecting terminal 1 to which the central office line L1 (L2) is connected, a hook switch 2 that opens and closes the central office line L1 (L2), and a dial number is sent. The dial number sending means 3 and the transmitting/receiving switching circuit (which automatically switches between transmitting and receiving by comparing the levels of transmitting and receiving)
(hands-free speech network) 4, a microphone 5, and a speaker 6.

Furthermore, a microprocessor (MPU) 7 that controls the telephone device, a voice input means 8 that amplifies the voice signal output from the microphone 5, and a voice recognition device that recognizes this voice signal and converts it into a dial number. means 9;
It is equipped with a call end detection means 12 that detects whether the other party has ended the call, and an infrared sensor 1 that detects the approach of a human body by detecting far infrared rays emitted from a human body.
1, and comparison means 10 for comparing the output of the infrared sensor 11 with a preset threshold value and determining whether or not the threshold value has been exceeded.
It is equipped with

Next, the operation of the telephone device configured as described above will be explained.

When the user brings his or her hand close to the infrared sensor 11, the infrared sensor 11 generates an output to the comparison means 10. Comparison means 10 compares this output with a preset threshold and applies a detection signal to microprocessor 7 if the threshold is exceeded.

Based on this detection signal, the microprocessor 7 determines that the user has approached, and operates the voice input means 8 to amplify the voice signal output from the microphone 5 and send it to the voice recognition means 9. lead.

When the user speaks the digits of the dial number into the microphone 5, the voice recognition means 9 recognizes the digits, converts them into a dial number, and inputs the digits into the microprocessor 7.

The microprocessor 7 operates the dial number sending means 3 and sends a dial signal converted into a dial number to the dial number sending means 3.
Furthermore, the hook switch 2 that opens and closes the office line L1 (L2) is closed, and the signal is sent through the office line connection terminal 1 and the office line L1 (L2).

[0014] Next, a hands-free telephone call will be explained.

When the user brings his or her hand close to the infrared sensor 11, the microprocessor 7 performs similar processing, determines that the user has approached, and operates the transmission/reception switching circuit 4.

After sending the dial number, a ringing tone is heard from the speaker 6 while the dialed party is being called. When the other party answers the call and makes a call, while the user is not speaking, the transmitting/receiving switching circuit 4 compares the transmitting and receiving levels and determines that the receiving level is higher than the transmitting level. Since it is judged that the other party's voice is loud, the other party's voice is sent to speaker 6.
more audible.

Next, when the user speaks into the microphone 5, the transmitting level becomes higher than the receiving level in the transmitting/receiving switching circuit 4, so that the transmitting level becomes higher than the receiving level. It determines that the user's voice is too loud and sends the user's voice to the other party.

When the other party ends the call, a BT sound is sent through the office line L1 (L2), so the call end detection means 12 detects this BT sound and sends a call end signal to the microprocessor 7. Then, the microprocessor 7
Open hook switch 2.

Even if the handset or the loudspeaker button is not visible in the dark, the detection signal obtained when the user approaches the telephone device facilitates voice dialing and hands-free calls.

In the embodiment described above, an infrared sensor is used as a means for detecting the approach of a human body, but other means such as a distance measuring means using ultrasonic waves may be used. .

[0021]

As is clear from the above description of the embodiments, according to the telephone device of the present invention, the voice input means 8 and the voice recognition means 9 are activated by the detection signal obtained when the user approaches the telephone device. It is possible to make a dial number by voice, and also to make hands-free calls without picking up the handset, making it extremely easy to use.
