摘要： Apparatus and method for recording data in a speech recognition system and recognizing spoken data corresponding to the recorded data. The apparatus and method responds to entered data by generating a string of phonetic transcriptions from the entered data. The data and generated phonetic transcription string associated therewith is recorded in a vocabulary lexicon of the speech recognition system. The apparatus and method responds to receipt of spoken data by constructing a model of subwords characteristic of the spoken data and compares the constructed subword model with ones of the recorded lexicon vocabulary recorded phonetic transcription strings to recognize the spoken data as the data identified by and associated with a phonetic transcription string matching the constructed subword string.

摘要： A speech recognition method implemented in a computer system recognizes words without requiring prior creation of models for such words based on spoken entries. A key word is entered in nonspoken form and a string of phonemes are defined by the speech recognizer to represent the new key word. A response signal is generated from each phoneme in the new key word model. Such response signals are utilized to define a multidimensional validity field for the new key word. Upon receipt of a spoken word from a user, a string of phonemes is assigned to represent the spoken word. A response signal from each phoneme in the model used to represent the spoken word is contrasted with the validity fields previously defined for the corresponding key word. A determination is made as to whether the spoken word is valid or not based on whether the response signals representing the spoken word lie within the validity fields.
摘要翻译：在计算机系统中实现的语音识别方法识别单词，而不需要基于语音输入事先创建这样的单词的模型。一个关键词以非说明形式输入，并且一串音素由语音识别器定义以表示新的关键词。从新的关键字模型中的每个音素生成响应信号。这样的响应信号用于定义新关键字的多维有效性字段。在从用户接收到口语单词时，分配一串音素来表示口语单词。来自用于表示口语单词的模型中的每个音素的响应信号与先前为相应的关键词定义的有效性字段形成对比。根据表示口语字的响应信号是否在有效性字段内，确定口语字是否有效。
