Speech recognition system and method for operating a speech recognition system with a mobile unit and an external server
First Claim
1. A transportation vehicle user interface voice recognition system comprising:
- a mobile unit provided on a transportation vehicle; and
an external server, wherein the mobile unit and the external server are in communication with each other, wherein the mobile unit comprises;
a memory that stores voice model data that comprise at least one expression set with expressions for controlling transportation vehicle functionality using voice input of a user;
a voice recognition unit configured to use the voice model data as a basis for producing a recognized text for captured voice input data generated based on the voice input of the user, wherein the recognized text is analyzed to determine how to control the transportation vehicle functionality; and
a data interface that at least intermittently sets up a data-oriented connection to a data interface of the external server,wherein the external server comprises;
a database with event data having associated time data and expressions for controlling transportation vehicle functionality, the external server being configured to produce update data for the voice model data stored in the memory of the mobile unit by comparing the time data associated with the event data with a current time,wherein the update data for the voice model data comprises at least expressions associated with the event data in the external server database,wherein the external server is further configured to transmit the update data from the external server to the data interface of the mobile unit,wherein the transmitted expressions are added to the stored at least one expression set based on the update data and a subset of expressions of the at least one expression set stored in the memory are erased from the memory based on the update data, andwherein the event data of the database further have associated geographical position data, wherein the voice recognition system further includes a position finding unit configured to determine a current position of the mobile unit, wherein position finding unit is configured to transmit the current mobile unit'"'"'s position to the external server, and wherein the update data are further produced by the external server by comparing the geographical position data associated with the event data with the mobile unit'"'"'s position.

Abstract
A voice recognition system having a mobile unit and an external server. The mobile unit includes a memory unit that stores voice model data having at least one expression set with expressions, a voice recognition unit, and a data interface that can set up a data-oriented connection to a data interface of the external server. The external server includes a database with event data having associated time data and expressions. The external server can, by comparing the time data associated with the event data with a current time, produce updated data that includes at least expressions associated with the event data of the database. The update data can be transmitted to the mobile unit. The update data can also be taken as a basis for adding the transmitted expressions to the expression set. Also disclosed is a method for operating a voice recognition system.

7. A method for operating a transportation vehicle user interface voice recognition system having a mobile unit and an external server, the method comprising:
-
storing voice model data that comprise at least one expression set with expressions in a memory of the mobile unit, wherein the expressions are for controlling transportation vehicle functionality using voice input of a user; producing a recognized text for captured voice input data based on the voice model data, wherein the recognized text is analyzed to determine how to control the transportation vehicle functionality; setting up a data-oriented connection to a data interface of the external server at least intermittently, wherein the external server comprises a database with event data that have associated time data and expressions for controlling transportation vehicle functionality; producing, by the external server, update data for the voice model data by comparing the time data associated with the event data with a current time, wherein the update data for the voice model data comprises at least expressions associated with the event data of the database; transmitting, by the external server, the update data to the mobile unit; and adding the transmitted expressions to the expression set based on the update data and erasing a subset of expressions of the at least one expression set from the memory based on the update data, wherein the event data of the database include associated geographical position data, wherein the voice recognition system further includes a position finding unit and the method further comprises the position finding unit determining and transmitting a current position of the mobile unit to the external server, and comparing the geographical position data associated with the event data with the mobile unit'"'"'s position by the external server as part of producing the update data. - View Dependent Claims (8, 9, 10, 11, 12)
