[0043] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0044] The dialogue system of the first embodiment is a system that acquires a voice command from a user (for example, a driver) in a vehicle, performs voice recognition, generates a response sentence based on the recognition result, and provides it to the user.

[0045]

[0046] figure 1 It is a system configuration diagram of the dialogue system of the first embodiment.

[0047] The dialogue system of this embodiment includes a vehicle-mounted terminal 10 and a voice recognition server 20 .

[0048] The in-vehicle terminal 10 is a device having the following functions: the function of acquiring the voice uttered by the user and performing voice recognition via the voice recognition server 20; and the function of generating a response sentence based on the voice recognition result and providing it to the user. The vehicle-mounted terminal 10 may be, for e...

no. 2 approach

[0093] The second embodiment is an embodiment in which an independent server device has the correction unit 12 and the response generation unit 16 in the first embodiment.

[0094] Figure 4 It is a system configuration diagram of the dialogue system of the second embodiment. In addition, the same code|symbol is attached|subjected to the functional block which has the same function as 1st Embodiment, and description is abbreviate|omitted.

[0095] In the second embodiment, a response generation server 30 as a server device that generates response sentences includes a response generation unit 32 and a correction unit 33 . The response generation unit 32 corresponds to the response generation unit 16 in the first embodiment, and the correction unit 33 corresponds to the correction unit 12 in the first embodiment. The basic functions are the same, so the description is omitted.

Abstract

The invention provides a voice recognition device and a voice recognition method. The voice recognition device comprises a voice acquisition unit that acquires voice given by a user; a voice recognition unit that recognizes the acquired voice to acquire a voice recognition result; a category classification unit that classifies a speech content of the user into a category, based on the voice recognition result; an information acquisition unit that acquires a category dictionary including words corresponding to the classified category; and a correction unit that corrects the voice recognition result, based on the category dictionary.

Description

technical field [0001] The present invention relates to a voice recognition device for recognizing an input voice. Background technique [0002] Voice recognition technology that recognizes voices uttered by users and processes them with computers using the recognition results has spread. By using voice recognition technology, computers can be operated in a non-contact manner, and the convenience of computers installed in mobile bodies such as automobiles has been greatly improved. [0003] The recognition accuracy at the time of voice recognition differs depending on the size of the dictionary used for the recognition. For example, there is a large difference in recognition accuracy between a workstation specialized for voice recognition and a personal computer not specialized for voice recognition. [0004] Therefore, when it is desired to use voice recognition in a small-scale computer, a method of transmitting voice data to a large-scale computer via a communication li...
