Abstract: A method and system for editing words that have been misrecognized. The system allows a speaker to specify a number of alternative words to be displayed in a correction window by resizing the correction window. The system also displays the words in the correction window in alphabetical order. A preferred system eliminates the possibility, when a misrecognized word is respoken, that the respoken utterance will be again recognized as the same misrecognized word. The system, when operating with a word processor, allows the speaker to specify the amount of speech that is buffered before transferring to the word processor.

Abstract: A method of recognizing speech, comprising:

receiving input data indicative of the speech to be recognized;
detecting pauses in the speech, based on the input data, to identify a phrase duration;
generating a plurality of phrase hypotheses representative of likely word phrases represented by the input data between the pauses detected;
comparing a word duration associated with each word in each phrase hypothesis, based on a number of words in the phrase hypothesis and based on the phrase duration, with an expected word duration for a phrase having a number of words equal to the number of words in the phrase hypothesis; and
assigning a score to each phrase hypothesis based on the comparison of the word duration with the expected word duration to obtain a most likely phrase hypothesis represented by the input data.

Abstract: A computer system for linearly encoding a pronunciation prefix tree. The pronunciation prefix tree has nodes such that each non-root and non-leaf node represents a phoneme and wherein each leaf node represents a word formed by the phonemes represented by the non-leaf nodes in a path from the root node to the leaf node. Each leaf node has a probability associated with the word of the leaf node. The computer system creates a tree node dictionary containing an indication of the phonemes that compose each word. The computer system then orders the child nodes of each non-leaf node based on the highest probability of descendent leaf nodes of the child node. Then, for each non-leaf node, the computer system sets the probability of the non-leaf node to a probability based on the probability of its child nodes, and for each node, sets a factor of the node to the probability of the node divided by the probability of the parent node of the node. Finally, the computer system generates an encoded pronunciation entry for each leaf node of the pronunciation prefix tree. Each encoded pronunciation entry indicates the word represented by the leaf node and contains the factor of a nearest ancestor node with a factor other than 1.0.

Abstract translation: 一种用于对发音前缀树进行线性编码的计算机系统。 发音前缀树具有节点，使得每个非根节点和非叶节点表示音素，并且其中每个叶节点表示由从根节点到叶节点的路径中的非叶节点表示的音素形成的词 。 每个叶节点具有与叶节点的单词相关的概率。 计算机系统创建包含组成每个词的音素指示的树节点词典。 计算机系统然后基于子节点的后代叶节点的最高概率来命令每个非叶节点的子节点。 然后，对于每个非叶节点，计算机系统基于其子节点的概率将非叶节点的概率设置为概率，并且对于每个节点，将节点的因子设置为节点的概率 除以节点的父节点的概率。 最后，计算机系统为发音前缀树的每个叶节点生成编码的发音条目。 每个编码的发音条目指示由叶节点表示的词并且包含具有非1.0的因子的最近的祖先节点的因子。
