| 9. | In this thesis , first we analyzed and designed a traditional continued speech recognition system , which based on hmm and mfcc speech features . then we researched some noise robust technologies based on that system
本论文首先分析并实现了一个以mel频率倒谱系数( mfcc )作为语音特征,基于隐马尔可夫模型( hmm ) ,针对连续数字串识别任务的基本连续语音识别系统。 |
| 10. | Each unit of a speech recognition system is studied in this paper , which includes the preprocessing , the training of reference patterns , the connected digit speech recognition algorithm and the postprocessing of confusing pairs . the research of endpoint detection includes the endpoint detection not only in the quiet environment but also in the low signal - to - noise ( snr ) situation . as far as the training of the reference patterns is concerned , the modified k - means algorithm is adopted . the most important part of this paper is the research of connected speech recognition algorithm . two kinds of algorithm are put forward , which are based on the existing fruit of mutual - information match theory
其次汉语连续数字发音连续程度较高，这主要由于汉语数字发音中零声母语音出现的较多。另外汉语连续数字串中各个数字的协同发音现象较严重也给汉语连续数字语音识别带来了困难。本文以互信息理论为基础，从语音模式间的交互信息量的角度，研究了一个完整的语音识别系统的各个组成部分，其中包括预处理、参考模式的训练、连续识别算法以及后续处理部分。 |
