Abstract (en)

[origin: WO2005013261A1] Disclosed is a method for speaker-dependent speech recognition, comprising the following steps: a speech signal (SS) encompassing a voice command is detected; the speech signal (SS) is divided (F) into time frames; the speech signal is characterized in each detected time frame by forming a corresponding property vector (F_IS); a property vector sequence is formed from one or several property vectors (F_IS); the property vector sequence is stored; the property vector sequence is allocated to a sequence of model vectors in a speech resource (HMM-L) comprising a plurality of model vectors; a piece of allocation information indicating allocation of the property vector sequence to a sequence of model vectors is stored; and the voice command allocated to the model vector sequence is identified.
