Connected digit speech recognition is a crucial branch of continuous speech recognition. it has a long time attracted the attentions of many researchers because it has wide applications such as speech autodialer, personal number verification, etc. mandarin connected digit speech recognition, for its own pronunciation characteristic ' s more difficult than english digit recognition
漢語連續數字語音識別是語音識別中的一個重要分支，同英語發音的識別情況相比還有一定的差距，主要難點在於，首先漢語是單音節字，音節越少語音間的混淆程度越高，識別越困難。 -
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
其次漢語連續數字發音連續程度較高，這主要由於漢語數字發音中零聲母語音出現的較多。另外漢語連續數字串中各個數字的協同發音現象較嚴重也給漢語連續數字語音識別帶來了困難。本文以互信息理論為基礎，從語音模式間的交互信息量的角度，研究了一個完整的語音識別系統的各個組成部分，其中包括預處理、參考模式的訓練、連續識別演算法以及后續處理部分。
