Abstract

A voice recognition apparatus 10, which performs voice recognition of an input voice by referring to a voice recognition dictionary and outputs a voice recognition result, has an external information acquiring section 14 for acquiring from externally connected devices 20-1-20-N connected thereto a type of each externally connected device, and for acquiring data recorded in each externally connected device; a vocabulary extracting analyzing section 15 and 16 for extracting a vocabulary item from the data as an extracted vocabulary item, and for producing analysis data by analyzing the extracted vocabulary item and by providing the extracted vocabulary item with reading; and a dictionary generating section 17 for storing the analysis data in the voice recognition dictionary corresponding to the type. For each type of the externally connected devices, one of the voice recognition dictionaries 13-1-13-N is assigned.

Claims

1. A voice recognition apparatus that carries out voice recognition of an input voice by referring to a voice recognition dictionary and outputs a voice recognition result, said voice recognition apparatus comprising:

an external information acquiring section for acquiring from an externally connected device connected thereto a type of the externally connected device, and for acquiring data recorded in said externally connected device;

a vocabulary extracting analyzing section for extracting a vocabulary item from the data as an extracted vocabulary item, and for producing analysis data by analyzing the extracted vocabulary item and by providing the extracted vocabulary item with reading; and

a dictionary generating section for storing the analysis data in the voice recognition dictionary corresponding to the type, wherein

said voice recognition dictionary is provided for each type of the externally connected device.

2. The voice recognition apparatus according to claim 1, wherein said dictionary generating section comprises:

a type deciding section for making a decision, when receiving the analysis data, as to whether the voice recognition dictionary corresponding to the type of the externally connected device is present or not;
