Abstract

PURPOSE: To efficiently register a voice pattern by using a small number of memories by dividing the voice pattern into fixed states and registering the continuous time in every state and the centroid of a feature vector of a frame belonging to the state. CONSTITUTION: The system is provided with a microphone 1, a feature sequence conversion means 5, a voice pattern dividing means 3, a centroid calculating means 4, a continuous time calculating means 5, and a reference pattern registering part 6. A voice inputted from the microphone 1 is converted into the time sequence of feature vectors by the means 2. At the time, a voice pattern is divided into the fixed number N (N>1) of states and the continuous time of each state and the centroid of a feature vector of a frame belonging to the state are registered in each state. Consequently a quality reference pattern can be prepared by using the small number of memories.
