Method for selecting a locality name in a navigation system by voice input
First Claim
1. A method for selecting a locality name in a motor vehicle navigation system in which said system contains a first and a second list with locality names, wherein said second list comprises a subset of the locality names contained in the first list together with the phonemes of said locality names, comprising:
- vocally inputting a desired locality name via a voice input system;
determining features of the vocally input desired locality name;
comparing the features of the vocally input desired locality name with features of the stored phonemes of the locality names in the second list; and
selecting a locality name if the features of the vocally input desired locality name sufficiently correspond to the features of the phonemes of a locality name in the second list;
or if the features of the vocally input desired locality name do not sufficiently correspond to the features of the phonemes of a locality name in the second list, requesting a further input of the desired locality name in a second form of input differing from the voice input of the desired locality name;
selecting a locality name from the first list by means of the second form of input; and
storing the selected locality name and the phonemes of the vocally input desired locality name in the second list.

Abstract
Disclosed is a method for selecting a locality name in a motor vehicle navigation system by voice input by means of a speaker-independent voice input system. A first list contains all locality names. In a second list, the locality names are entered which have already been entered once into the system, the phonemes being additionally entered. In the case of a repeated voice input of a locality name, the search is first performed in the second list.

9. A navigation system for a motor vehicle comprising:
-
a voice input system for converting spoken words into a plurality of features;
a first data source comprising a non-volatile storage element for storing data comprising a list with locality names;
a second data source for storing some of the data of the first data source; and
a control unit for selecting a locality name on the basis of the features supplied by the voice input system. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
