基于模糊聚类决策树的分布式语者识别算法
Distributed Speaker Identification Algorithm with Fuzzy Clustering Decision Tree
摘要
Abstract
In order to solve the problems of additive noise and high computational complexity in speaker identification and to improve the robustness and anti-noise ability of the large scale speaker identification algorithm,a distributed speaker identification algorithm with fuzzy clustering decision tree has been presented,which divides training data into several parts,and builds fuzzy clustering decision trees for these parts.For testing data,fuzzy decision trees has been employed,which are built in the previous step to decide which leaf node the people's speech belongs to.The speaker is identified by using the Mel-Frequency Cepstral Coefficients and the Gauss mixture model identification method on the selected leaf nodes.The process of fuzzy clustering on training data mainly includes four parts,i.e.extracting feature data from the corresponding layer,calculating the mean and standard deviation of the feature data,using Lloyd algorithm to get the separation vector,clustering to get the nodes of the next layer.The experimental result shows that compared with the traditional hard clustering algorithm,the proposed algorithm has improved the accuracy and classification efficiency of speaker identification,with the good anti-interference ability to the additive noise.关键词
