[0002]

2. Description of the Related Art Conventionally, a vehicle such as an automobile uses a remote control device for remotely operating equipment. By using the remote control device, for example, the driver can operate various equipment without moving the seat. In addition, a keyless entry system that can unlock or lock a door without directly inserting a key when entering or exiting a door of a vehicle has been widely used.

[0003] However, if remote control is possible with the remote controller, a problem arises when the remote controller is stolen. A key for a keyless entry system or the like can enter a vehicle only by being possessed by a stolen person, and the vehicle itself may be stolen.

[0004] Even if remote control is possible with the remote control device, if the remote control device must be operated by hand, operation becomes difficult or dangerous when the hand is full, such as during driving of a vehicle. In addition, it is difficult for even a handicapped person to operate. Therefore, it is conceivable to enable a plurality of types of operations only by inputting a descriptive word to the remote control device by voice. The applicant of the present application has disclosed, for example,
No. 189 discloses an in-vehicle voice recognition device capable of recognizing an occupant's voice and releasing at least a door lock, a fuel filler lid lock, and a trunk lock. In this prior art, a speaker verification technique for confirming an individual based on personal information included in a voice signal is applied to determine a user, thereby improving security and facilitating operation.

A prior art concerning a voice collating device for performing locking and unlocking with a voice key is disclosed, for example, in Japanese Patent Laid-Open No. Hei 5-98859. In this prior art, voice information of a specific person is statistically analyzed with respect to a frequency representing personality, and stored in advance as voice key information to identify an individual at the time of voice information input. Prior arts that use voiceprint information indicating characteristics of an individual by voice as ID information and manage entry / exit to a specific area are disclosed in JP-A-5-263558 and JP-A-8-3263.
81 and the like. Further, JP-A-5-2879
In an IC card 49, voice parameters representing voice characteristics are stored in the IC card, and when an electronic lock device that locks and unlocks electronically using the IC card is used, the voice of the user is used. Prior art that unlocks a lock only when input key information matches key information read from an IC card is disclosed.

[0006]

In each of the above-mentioned prior arts, at the time of voice recognition, speaker verification is performed as in, for example, Japanese Patent Application Laid-Open No. 7-44189, and an individual is confirmed by personal information included in a voice signal. So the security is improved. As in Japanese Patent Application Laid-Open No. Hei 5-263558, the use of voiceprint information can provide the same high security as the use of fingerprint information. However, each prior art speech recognition does not consider remote control operation. Therefore, it can be used only in a range where voice input is performed at a sufficient volume. Loudly trying to perform an operation from a distance can be useful in a quiet environment,
It is not preferable at night. Increasing the voice input sensitivity is more susceptible to ambient noise, etc.
Not preferred.

An object of the present invention is to provide a voice recognition remote control device which can be remotely operated by voice input and can be used only by a person who has a certain usage qualification, such as the user himself or a person who has been authorized. It is.

If it is determined that they match, step b6
To allow input. When the input is permitted, in step b7, the speech recognition circuit 8 performs a speech recognition process on the speech signal, and extracts an instruction word included in the speech signal. In step b8, the content of the extracted descriptive word is identified. In step b9, a signal for remote operation corresponding to the descriptive word is transmitted from the signal transmission circuit 9, and the procedure ends in step b10. Actually, for example, when the user himself / herself utters a sound "door unlock" to the microphone 2, the speaker identification circuit 4 samples the sound and generates an ID code corresponding to the voice print. . When the ID codes match, the voice recognition circuit 8 recognizes the meaning of "door unlock", and the signal transmission circuit 9 transmits a signal corresponding to the door unlock. In the present embodiment, a description will be given of transmitting a control signal corresponding to each descriptive word. However, regardless of the content of the voice, if the user's voiceprint matches, a predetermined fixed control is performed. A signal may be transmitted.
