1. A method for speaker-dependent speech recognition, comprising: capturing a speech signal, including a speech command, of a speaker; breaking down the speech signal into time frames; characterizing the speech signal in each captured time frame by forming a corresponding feature vector; forming a language-independent feature vector sequence from at least one feature vector; storing the language-independent feature vector sequence; assigning the language-independent feature vector sequence to a language-dependent sequence of model vectors in a first language resource which includes a multiplicity of language-dependent model vectors; storing first assignment information which specifies assignment of the language-independent feature vector sequence to the language-dependent sequence of model vectors; recognizing the speech command which is assigned to the language-dependent sequence of model vectors; selecting a second language resource different from the first language resource; assigning the language-independent feature vector sequence previously stored to a language-dependent model vector sequence in the second language resource; and storing second assignment information regarding said assigning of the language-independent feature vector sequence to the language-dependent model vector sequence in the second language resource.
