Abstract
A method for operating a navigation system analyzes several address components to determine the most likely address desired by a user. The navigation device includes a receiving device on which an acoustic address input consisting of several input components can be registered. The input components of the address are analyzed with a speech recognition module, wherein at least one geographical location, which is defined by an address with several address components, is selected from a database for further processing depending on the result of the speech recognition analysis. The method includes analyzing several address component combinations to determine the most likely address inputted by the user.
Claims11
A method for operating a navigation system, including a receiving device on which an acoustic address input consisting of several input components can be registered, wherein the input components of the address are analyzed with a speech recognition module, and wherein at least one geographical location, which is defined by an address with several address components, is selected from a database for further processing depending on the result of the speech recognition analysis, said method comprising:
- a) a speech recognition analysis is performed for a first input component, wherein several possible first address components are selected from the database depending on the result of the speech recognition analysis for the first input component, and wherein a match value is calculated for each of these alternative first address components to quantify the acoustic match with the first input component;
- b) a speech recognition analysis is performed for at least a second input component, wherein several possible second address components are selected from the database depending on the result of the speech recognition analysis for the second input component, and wherein a match value is calculated for each of these alternative second address components to quantify the acoustic match with the second input component;
- c) a combination evaluation is calculated for each of the various combinations of each different first and second address component, which combination evaluation is based on the match values of the address components in various combinations with each other.

- d) receiving an audible second input component in the receiving device of the navigation device;
- e) performing a speech recognition analysis for the second input component using the speech recognition module, wherein several possible second address components are selected from the database depending on the result of the speech recognition analysis for the second input component;
- f) calculating a match value for each of these alternative second address components to quantify the acoustic match with the second input component;
- g) calculating a combination evaluation for each of the various combinations of each different first and second address component, which combination evaluation is based on the match values of the address components in various combinations with each other;
- h) selecting the combination of first and second address components having the highest combination evaluation;
- and
- g) offering the selected combination of first and second address components having the highest combination evaluation to a user via at least one of visual display and audible announcement.
