摘要
在分析汉语数字串语音特点的基础上,设计出了基于层级策略的连续数字串识别系统。该系统先对连续数字串进行确定性的预分割,再用LevelBuilding算法对每个分割段进行基于模板模糊分组的识别,在该识别结果的基础上利用加权矩阵识别算法进一步区分易混淆语音对。该系统在计算时间减少到原来的35.2%的同时识别率提高到94.08%。
By analyzing the characters of mandarin connected digit speech,a recognition system based on hierarchical method is given.In this system,the first step is to find the correct dividing point in digit string,then each segment is recognized by using level building method based on fuzzy digit pattern group,finally the weighted matrix algorithm is used to distinguish the confusable digit pair.Experiments demonstrate that the correct recognition rate of the system is improved to94.08%meanwhile the recognition time is decreased to34.2%.
