说明：  隐马尔可夫模型工具包（HTK）是一种便携式工具包构建和操纵隐马尔可夫模型。 HTK主要用于语音识别的研究，虽然它已被用于许多其它应用，包括研究，语音合成，字符识别和DNA测序。 HTK是使用在世界各地的数百个网站。 该文档主要包含htkbook的中英文版本，方便HTK初学者使用和学习。
(The Hidden Markov Model Toolkit (HTK) is a portable toolkit for building and manipulating hidden Markov models. HTK is primarily used for speech recognition research although it has been used for numerous other applications including research into speech synthesis, character recognition and DNA sequencing. HTK is in use at hundreds of sites worldwide. This document consists mainly of Chinese and English versions htkbook facilitate HTK beginners to use and learn.)
