JPS61117962A - Device control system by voice - Google Patents

Abstract

PURPOSE:To attain device control by the voice of a specific subscriber by adjusting an exchanged voice level and an input level to a recognizer and reading the result of voice recognition to allow a personal computer to control a device to be controlled. CONSTITUTION:When a subscriber 1 makes a phone call to its own home, a call signal from a trunk 3 is received by a subscriber adaptor 4, which gives an incoming signal to the personal computer 7. When the computer 7 detects an incoming signal, the computer 7 commands the start of recognition to a voice recognizing device 6. The voice from the subscriber 1 is inputted to the voice recognizer 6 via a trunk 3, an exchange 2, the subscriber adaptor 4 and a level exchange 5 from the exchange 2 and a message is transmitted to the computer 7. The computer 7 analyzes the received message to control the device 8 to be controlled. Then when the subscriber 1 completesthe message and the handset is hooked on, a restoration signal is transmitted to the computer 7 from the trunk 3 via the subscriber adaptor 4, the voice recognizer 6 receives a recognition stop command, an open command signal is transmitted to the subscriber adaptor 4 and the exchange 2 receives the restoration signal.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device control system that relies on voice transmitted through a switching network.

(Prior Art) Conventionally, when controlling equipment by recognizing the voice transmitted from a switched circuit network, a very expensive device that recognizes only the voice of a specific subscriber and controls the equipment has been used.・Additionally, when controlling equipment through a switched circuit network, special PB signals were used instead of voice.

(Problems to be Solved by the Invention) Due to the above-mentioned configuration, the conventional device control system has the inconvenience of being unable to control the device to be controlled without using an expensive recognition device or PB telephone.

The purpose of the present invention is to match the interface to the exchange side,
In addition to adjusting the exchange voice level and recognition device input level, the recognition results of the voice from the microphone are read and processed by a personal computer.

The object of the present invention is to eliminate the above-mentioned drawbacks by controlling the controlled equipment, and to provide a system for controlling equipment by the voice of a specific subscriber through a switching network using an inexpensive device.

(Means for Solving the Problems) The voice-based device control method configured according to the present invention is equipped with a switch and a trunk to form a switching circuit network, and recognizes the voice of a specific subscriber to control the device. It is realized by being equipped with a subscriber addition device, a voice recognition device, a level exchange device, and a personal computer so that external equipment can be controlled by the voice of a specific subscriber.

The subscriber add-on equipment is for interfacing with the equipment of the exchange.

The audio mm device is for recognizing the voice from the microphone.The level conversion device is for adjusting the exchanged voice level from the subscriber addition equipment to the input level of the voice recognition device.

The personal computer is designed to read the voice recognition results output from the voice recognition device and control external equipment. explain.

FIG. 1 is a block diagram showing an embodiment for implementing the present invention.
5 is a level exchange device, 6 is a voice lllll1m device, 7 is a personal computer, 8 is a controlled device, 9 is an additional device control signal line, 1o is a voice recognition device control signal line, 11 is a device control! ll signal line.

Next, an overview of the operation of the device control method shown in FIG. 1 will be explained.

When the subscriber 1 calls home, a calling signal is sent to the trunk ■J subscriber additional device 4. When the subscriber attachment device 4 receives the paging signal, it sends an incoming call signal to the personal computer 7 through the attachment device control signal ls9. When the personal computer 7 detects an incoming call signal, it instructs the voice recognition device 6 to start recognition through the voice recognition device control signal 1110, and sends a response signal to the subscriber addition device 4 through the addition device control signal I19. When the subscriber addition device 4 receives the response signal, it sends the response signal to the trunk 3. Voice from subscriber 1 is input from exchange 2 to trunk fiber device 6. When the voice recognition device 6 receives a voice message from the subscriber 1, it transmits the message to the personal computer via the voice recognition device control signal alto.

The personal computer 7 analyzes the received message and controls the controlled device 8 via the device control signal $111.

Next, when the subscriber 1 finishes the message and the handset is disconnected, a recovery signal is sent from the trunk δ to the subscriber addition device 4. When the subscriber additional equipment ft4 receives the restoration signal, it sends an additional equipment control signal t4L to the personal computer 7 via the additional equipment control signal 1i91.

and sends a recovery signal. When the personal computer 7 detects the recovery signal, it instructs the voice recognition device 6 to stop recognition via the voice recognition device control signal $110, and also sends an instruction to the subscriber additional device 4 through the addition device control signal Is9. Sends an open instruction signal. When the subscriber addition device 4 receives the release instruction signal, it sends a restoration signal to the exchange 2.

(Effects of the Invention) As explained above, the present invention adjusts the interface to the exchange side, adjusts the exchange voice level and the input level of the recognition device, and reads the recognition result of the voice from the microphone to be processed by the personal computer. By controlling the control equipment, it is possible to control the equipment by voice from the switched circuit network at low cost by simply installing commercially available equipment and simple additional equipment.
