Speech recognition pattern adaptation system using tree scheme |
摘要 |
Pattern matching means 3 matches categories of a reference pattern stored in reference pattern memory means 2 and input samples of an input pattern produced by input pattern generating means 1. Data statistics estimating means 6 calculates the numbers of input samples in individual nodes of a tree scheme reference pattern stored in the tree scheme reference pattern memory means 4. Node selecting means 6 selects nodes used for adaptation according to the input sample numbers calculated by the data statistics estimating means 5. Adaptation parameter generating means 7 calculates an adaptation parameter in the Nodes selected by the node selecting means 6. Reference pattern generating means 8 produces an adapted reference pattern using the calculated adaptation parameter.
