摘要： PROBLEM TO BE SOLVED: To provide a speech recognition apparatus which suppresses the number of recognition vocabularies and has efficient operability since a practical speech recognition apparatus needs to secure recognition precision, secure sufficient recognizable vocabularies, and facilitate input, although recognition precision becomes lower and the efficiency of input operation decreases as vocabularies to be recognized in speech recognition increase.
SOLUTION: A storage device for speech recognition is constituted in a hierarchical structure and the inclusion range is made gradually narrower; and recognition processing is performed while next spoken contents are predicted. At the same time, upper layers are so corrected at a proper time that a long phrase can be inputted as the skill of a user is improved, and a vocabulary of low use frequency is replaced with a new vocabulary.

摘要： PROBLEM TO BE SOLVED: To correct easily one part of input contents when an error is caused in voice recognition of inputted voice.
SOLUTION: In a voice recognition device recognition a plurality of continuous words, voice inputted to a voice input device 10 is voice-recognition- processed by a voice recognition unit 20. A voice recognized result is outputted from a voice output device 50 by voice. When it is judged that the recognized result voice-outputted is erroneous, an operator performs voice-input for correcting a word being erroneously recognized while recognized voice is being outputted. That is, when voice is inputted again while the recognized result is voice-outputted, the voice recognizing unit 20 performs partial word correction of voice initially inputted based on voice inputted again.

摘要翻译：要解决的问题：当输入语音的语音识别出现错误时，可以轻松地纠正输入内容的一部分。解决方案：在识别多个连续字的语音识别装置中，输入到语音输入装置10的语音由语音识别单元20进行语音识别处理。语音识别结果从语音输出装置50输出通过声音。当判断出语音输出的识别结果是错误的时，操作者执行语音输入，用于校正正在输出识别的语音时错误识别的单词。也就是说，当语音输出被识别结果再次输入语音时，语音识别单元20对再次输入的语音最初输入的语音进行部分字校正。版权所有（C）2004，JPO
