Speech recognition system and data updating method
First Claim
1. A speech recognition system installed in a terminal coupled to a server via a network, wherein:
- the terminal holds map data including a landmark;
the speech recognition system manages recognition data including a word corresponding to a name of the landmark included in the held map data, and sends update area information indicating an area of the map data to be updated and update data on the area indicated by the update area information to the server;
the server is configured to;
generate, in a case of which recognition data of the area indicated by the update area information sent from the terminal has been changed, after a time indicated by the update data sent from the terminal, difference data between latest recognition data and recognition data corresponding to the area indicated by the update area information at a time indicated by the update data; and
send the generated difference data to the terminal along with map data on the area indicated by the update area information;
the terminal updates the map data held in the terminal based on the map data sent from the server; and
the speech recognition system updates the recognition data managed by the terminal based on the difference data sent from the server;
wherein;
the recognition data includes confusion information, the confusion information including a confusion word having a tendency to cause a recognition error with the word corresponding to a name of the landmark, and a confusion score which represents the tendency of the confusion word to cause recognition error;
the server sends the difference data including the confusion information to the terminal; and
the speech recognition system updates the confusion information included in the recognition data held by the terminal based on the confusion information sent from the server.

Abstract
It is provided a speech recognition system installed in a terminal coupled to a server via a network. The terminal holds map data including a landmark. The speech recognition system manages recognition data including a word corresponding to a name of the landmark, and sends update area information and updated time to the server. The server generates, when recognition data of the area of the update area information sent from the terminal has been changed after updated time, difference data between latest recognition data and recognition data of the update area information at a time of the updated time, and sends the generated difference data and map data of the update area information to the terminal. The terminal updates the map data based on the map data sent from the server. The speech recognition system updates the recognition data managed by the terminal based on the difference data.

8. A data updating method for a terminal coupled to a server via a network,
the terminal including a speech recognition system and holding map data including a landmark, the speech recognition system managing recognition data including a word corresponding to a name of the landmark included in the held map data, the data update method comprising the steps of: -
sending, by the terminal, update area information indicating an area of the map data to be updated, and update data on the area to be updated to the server; generating, by the server, in a case of which recognition data of the area indicated by the update area information sent from the terminal has been changed, after a time point indicated by the update data sent from the terminal, difference data between latest recognition data and recognition data corresponding to the area indicated by the update area information at a time indicated by the update data; sending, by the server, the generated difference data to the terminal along with map data on the area indicated by the update area information; updating, by the terminal, the map data held in the terminal based on the map data sent from the server; and updating, by the terminal, the managed recognition data based on the difference data sent from the server; wherein; the recognition data includes confusion information, the confusion information including a confusion word having a tendency to cause a recognition error with the word corresponding to a name of the landmark, and a confusion score which represents the tendency of the confusion word to cause recognition error; the server sends the difference data including the confusion information to the terminal; and the method further comprises the step of updating, by the terminal, the confusion information included in the recognition data held by the terminal based on the confusion information sent from the server. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A speech recognition apparatus, comprising:
-
a server; and a terminal, coupled to a server via a network, that stores map data including a landmark, the terminal being configured to manage recognition data, and configured to send, to the server, update area information indicating an area of the map data to be updated, and update data on the area indicated by the update area information; wherein the recognition data includes a word corresponding to a name of the landmark included in the map data, and the recognition data also includes confusion information, the confusion information including a confusion word having a tendency to cause a recognition error with the word corresponding to a name of the landmark, and a confusion score which represents the tendency of the confusion word to cause recognition error; wherein when recognition data of the area indicated by the update area information sent from the terminal has been changed, after a time indicated by the update data sent from the terminal; the server is configured to generate difference data between latest recognition data and recognition data corresponding to the area indicated by the update area information at a time indicated by the update data, and then to send the generated difference data, including confusion information, to the terminal, along with map data on the area indicated by the update area information; the terminal is configured to update the map data stored in the terminal based on the map data sent from the server, to update the recognition data managed by the terminal based on the difference data sent from the server, and to update the confusion information included in the recognition data stored by the terminal based on the confusion information sent from the server. - View Dependent Claims (16, 17, 18, 19, 20)
