Abstract

A voice recognition search apparatus includes: a dictionary create unit creating a first voice recognition dictionary from a search subject data; a voice acquisition unit acquiring first and second voices; a voice recognition unit creating first and second text data by recognizing the first and second voices using the first and second voice recognition dictionaries; a first search unit searching the search subject data by the first text data; and a second search unit searching a search result of the first search unit by the second text data.

Claims

1. A voice recognition search apparatus comprising:

a search subject data storage unit configured to store search subject data being updated;

a dictionary create unit configured to create a first voice recognition dictionary from the search subject data dynamically;

a voice acquisition unit configured to acquire first and second voices;

a voice recognition unit configured to create first text data by recognizing the first voice using the first voice recognition dictionary and converting the first voice into a text, and configured to create second text data by recognizing the second voice using a second voice recognition dictionary and converting the second voice into a text;

a first search unit configured to search the search subject data by the first text data as a first search keyword; and

a second search unit configured to search a search result of the first search unit by the second text data as a second search keyword.

2. The apparatus of claim 1, wherein the dictionary create unit creates the first voice recognition dictionary by combining vocabularies dynamically created from the search subject data and fixed vocabularies with each other.

3. The apparatus of claim 1, wherein the dictionary create unit creates the second voice recognition dictionary based on the search result.

4. The apparatus of claim 1, wherein the dictionary create unit creates the second voice recognition dictionary by combining vocabularies created from the search result and fixed vocabularies with each other.

5. The apparatus of claim 1, wherein the second voice recognition dictionary is composed of fixed vocabularies.

6. The apparatus of claim 1, further comprising:

a dictionary switching unit configured to switch a voice recognition dictionary being used by the voice recognition unit from the first voice recognition dictionary to the second voice recognition dictionary when the display unit displays the search result.

7. The apparatus of claim 1, further comprising:

a candidate recommendation unit configured to recommend a candidate of the second voice effective in search by the second search unit based on the search result.

8. A voice recognition search method comprising:

creating a first voice recognition dictionary dynamically based on search subject data being updated sequentially stored in a search subject data storage unit;

acquiring first and second voices;

creating first text data by recognizing the first voice using the first voice recognition dictionary and converting the first voice into a text;

creating second text data by recognizing the second voice using a second voice recognition dictionary and converting the second voice into a text;

searching the search subject data by the first text data as a first search keyword; and

searching a search result of the first search keyword by the second text data as a second search keyword.

9. The method of claim 8, wherein creating the first voice recognition dictionary comprises creating the first voice recognition dictionary by combining vocabularies dynamically created from the search subject data and fixed vocabularies with each other.

10. The method of claim 8, further comprising:

creating the second voice recognition dictionary based on the search result.

11. The method of claim 8, further comprising:

creating the second voice recognition dictionary by combining vocabularies created from the search result and fixed vocabularies with each other.

12. The method of claim 8, wherein the second voice recognition dictionary is composed of fixed vocabularies.

13. The method of claim 8, further comprising:

switching a voice recognition dictionary being used in a voice recognition from the first voice recognition dictionary to the second voice recognition dictionary when the search result are displayed.

14. The method of claim 8, further comprising:

recommending a candidate of the second voice effective in search by the second search keyword based on the search result.
