Abstract

There are provided a voice recognition system, a device, a voice recognition method, a voice recognition program and a computer-readable recording medium in which the audio recognition program is recorded in order to be able to implement at least one of audio recognition above vocabulary processed by one device and retention of appropriate vocabulary stored in one device. Audio data received by a client are recognized by an audio recognition engine and when its recognition result is rejected, the audio data is transmitted to a server and the recognition result in the server is transmitted to the client. The client updates a recognition dictionary according to the number of recognitions and integrates the recognition results in a result integration part. The client may be used instead of the server.

7. A device according to claim 5 or 6, comprising storing means for storing vocabulary and updating means for updating the vocabulary stored in said storing means, and said updating means receives information referring to vocabulary from at least one or more other devices and updates the vocabulary stored in said storing means.

8. A device according to any one of claims 5 to 7, which starts connection to at least one or more other devices on a condition that a predetermined event occurs.

9. A device in a voice recognition system consisting of a plurality of devices, comprising audio receiving means for receiving said audio data;

second audio recognition means for recognizing said audio data; and

second transmitting means for transmitting a recognition result of said second audio recognition means to the destination device of said audio data, from a first device comprising;

audio input means to which audio data is input;

first audio recognition means for recognizing said audio data;

first transmitting means for transmitting said audio data to another device in a predetermined case;

receiving means for receiving a recognition result of said audio from the destination device of said audio data; and

result integration means for outputting a recognition result of the audio according to at least one of a recognition result in said first audio recognition means and the recognition result received by said receiving means.

10. A device according to claim 9, wherein a predetermined case said first transmitting means transmits said audio data to another device is a case a degree of reliability in the recognition result by said first audio recognition means is not more than a predetermined threshold value.

11. A method of recognizing audio in a device in a voice recognition system consisting of a plurality of devices comprising:

an input step of inputting audio data;
