Description: 语音识别（Speech Recognition）是让机器通过识别和理解过程把语音信号转变为相应的文本或命令的技术。在课题中，通过采用DTW（Dynamic time warping, 动态时间伸缩）算法，对实现孤立词的识别进行了初步探讨和研究，实现了在MATLAB软件环境下孤立词语的语音识别，并针对DTW的主要特点及不足做出了总结。-Speech Recognition (Speech Recognition) machines is through recognition and understanding of a process which put the voice signal into the corresponding text or command technology. The issue, through the use DTW (Dynamic time warping, dynamic time telescopic) algorithm to achieve an isolated word recognition conducted a preliminary exploration and study, the realization of the MATLAB software environment isolated words of Speech Recognition and DTW against the main features and deficiencies make summarized.

Description: 计算所汉语词法分析系统ICTCLAS介绍
词是最小的能够独立活动的有意义的语言成分。 但汉语是以字为基本的书写单位，词语之间没有明显的区分标记，因此，中文词语分析是中文信息处理的基础与关键。为此,我们中国科学院计算技术研究所在多年研究基础上，耗时一年研制出了汉语词法分析系统ICTCLAS(Institute of Computing Technology, Chinese Lexical Analysis System)，该系统的功能有：中文分词；词性标注；未登录词识别。分词正确率高达97%以上，未登录词识别召回率均高于90%，其中中国人名的识别召回率接近98%处理速度为31.5Kbytes/s。ICTCLAS的特色还在于：可以根据需要输出多个高概率结果，有多种输出格式，支持北大词性标注集，973专家组给出的词性标注集合。该系统得到了专家的好评，并有多篇论文在国内外发表。
计算所汉语词法分析系统ICTCLAS同时还提供一套完整的动态连接库ICTCLAS.dll和相应的概率词典,开发者可以完全忽略汉语词法分析，直接在自己的系统中调用ICTCLAS，ICTCLAS可以根据需要输出多个高概率的结果，输出格式也可以定制，开发者在分词和词性标注的基础上继续上层开发。-calculation Chinese lexical analysis system ICTCLAS introduced the term is the smallest independent of meaningful activities language components. It is Chinese characters written for the basic unit, the word no clear distinction between markers, therefore, the Chinese term analysis of the Chinese information processing infrastructure and key. To this end, we CAS Institute of Computing Technology based on years of research, 976,000 developed the Chinese lexical analysis system ICTCLAS (Institute of Compu Hosiery Technology, Chinese Lexical Analysis System), the system functions : the Chinese word; tagging; Unknown word recognition. Word accuracy rate of as high as 97%, unknown word recognition recall rate is higher than 90%. these names identify the recall rate of nearly 98% for the proce Platform: |
