摘要： A method for automatically analyzing a document in a speech recognition system having a vocabulary and language model can include the steps of: determining whether the document has undergone previous analysis; undoing the previous analysis; and, analyzing the document. More specifically, the determining step comprises the steps of: comparing trigrams in the document with trigrams in the language model; and, setting a reference point containing document data for undoing a previous analysis in the undoing step if the compared language model contains all the document trigrams. Moreover, the undoing step comprises the step of removing from the language model each trigram contained in the document data in the reference point. Finally, the analyzing step comprises the steps of: searching the document for new words not contained in the vocabulary; adding said new words to said vocabulary; updating the language model with trigrams contained in the document; and, setting a reference point containing document data for undoing the updating of the language model in the updating step. In addition, the adding step can comprise identifying among the new words found in the searching step, correctly-spelled words not requiring a speaker-supplied pronunciation; and adding the correctly-spelled words to the vocabulary. The inventive method can further comprise the steps of: recognizing a request from a user of the speech dictation system to discontinue user editing; finding in the document new words not contained in the vocabulary in response to the request; enhancing the vocabulary with the new words; undoing the analysis created during the analyzing step; and, further analyzing the document.
摘要翻译：用于在具有词汇和语言模型的语音识别系统中自动分析文档的方法可以包括以下步骤：确定文档是否经历了先前的分析; 取消以前的分析; 并分析文件。更具体地，确定步骤包括以下步骤：将文档中的三角形与语言模型中的三角形进行比较; 并且如果比较的语言模型包含所有文档三元组，则在撤消步骤中设置包含用于撤销先前分析的文档数据的参考点。此外，撤销步骤包括从包含在参考点中的文档数据中的每个三元组的语言模型中移除的步骤。最后，分析步骤包括以下步骤：在文档中搜索不包含在词汇表中的新单词; 将新词添加到所述词汇表中; 用文档中包含的三元组更新语言模型; 并且在更新步骤中设置包含用于撤销所述语言模型的更新的文档数据的参考点。此外，添加步骤可以包括在搜索步骤中找到的新词之间识别不需要说话人提供的发音的正确拼写的单词; 并将正确拼写的单词添加到词汇表中。本发明的方法还可以包括以下步骤：识别来自语音听写系统的用户的中断用户编辑的请求; 在文件中查找不包含在词汇中的新单词以响应请求; 用新词增强词汇; 解除分析步骤中创建的分析; 并进一步分析文件。
