    • A method and apparatus for recognizing an input identifier on the basis of a set of comparison identifiers. After a user provides the input identifier according to a first form, the present invention provides a recognized identifier based on the input identifier. The present invention then generates a plurality of comparison identifiers on the basis of the recognized identifier. The user is then prompted to provide the input identifier again, but this time according to a second form that is different than the first form. A second recognized identifier is then generated on the basis of the input identifier provided according to the second form. If a match exists between the second recognized identifier and one of the comparison identifiers, the matched comparison identifier is selected as corresponding to the input identifier.
    • 一种用于基于一组比较标识符识别输入标识符的方法和装置。 在用户根据第一形式提供输入标识符之后,本发明基于输入标识符来提供识别的标识符。 然后,本发明基于识别的标识符生成多个比较标识符。 然后提示用户再次提供输入标识符,但是这次根据与第一形式不同的第二形式。 然后基于根据第二形式提供的输入标识符生成第二识别标识符。 如果在第二识别标识符与比较标识符之一存在匹配,则匹配的比较标识符被选择为与输入标识符相对应。

    • A method and apparatus for reducing a set of reference identifiers to a candidate subset of reference identifiers. The reference identifiers are associated in memory with a plurality of index codes. A user provides an input identifier, causing a recognizing device of the present invention to produce a recognized identifier on the basis of the input identifier. The present invention determines an index code based on the recognized identifier and on the basis of a plurality of pre-stored confusion sets of characters that group together in individual confusion sets those characters having a relatively high likelihood of being confused with each other by the recognizing device. After matching the determined index code with one of the reference index codes, the present invention determines which reference index codes are within a predetermined distance of the matched reference index code. The reference identifiers that are associated with these reference index codes constitute the candidate subset of reference identifiers.
    • 一种用于将一组参考标识符减少到参考标识符的候选子集​​的方法和装置。 参考标识符与存储器中的多个索引代码相关联。 用户提供输入标识符,使得本发明的识别装置基于输入标识符产生识别的标识符。 本发明基于所识别的标识符来确定索引码,并且基于多个预先存储的混合字符集,基于将各个混淆集合在一起的那些具有相对较高的彼此混淆的可能性的字符通过识别 设备。 在将确定的索引代码与参考索引代码之一进行匹配之后,本发明确定哪些参考索引代码在匹配的参考索引代码的预定距离内。 与这些参考索引代码相关联的参考标识符构成参考标识符的候选子集​​。

    • A method and apparatus recognize an identifier entered by a user. A caller enters a predetermined identifier through a voice input device or a touch-tone keypad of a telephone handset. A signal representing the entered identifier is transmitted to a remote recognizer, which responds to the identifier signal by producing a recognized output intended to match the entered identifier. The present invention compares this recognized identifier with a list of valid reference identifiers to determine which one of these reference identifiers most likely matches the entered identifier. In performing this determination, the present invention compares each character of the recognized identifier with a character in a corresponding character position of each reference identifier in light of a plurality of confusion sets. On the basis of this comparison, the set of reference identifiers is reduced to a candidate set of reference identifiers, from which a reference identifier that matches the input identifier provided by the user.
    • 方法和装置识别用户输入的标识符。 呼叫者通过电话听筒的语音输入装置或按键式键盘输入预定标识符。 表示输入的标识符的信号被发送到远程识别器,远程识别器通过产生用于匹配输入的标识符的识别的输出来响应标识符信号。 本发明将该识别的标识符与有效参考标识符的列表进行比较,以确定这些参考标识符中的哪一个最可能与输入的标识符匹配。 在执行该确定时,本发明根据多个混淆集合将识别的标识符的每个字符与每个参考标识符的对应字符位置中的字符进行比较。 基于该比较,参考标识符的集合被减少到参考标识符的候选集合,参考标识符与用户提供的输入标识符匹配。

    • A method and apparatus for recognizing an identifier entered by a user. A caller enters a predetermined identifier through a telephone handset. A signal representing the entered identifier is transmitted to a remote recognizer, which responds to the signal by producing a recognized output intended to match the entered identifier. The present invention compares this recognized identifier with a list of valid reference identifiers to determine which one of these reference identifiers most likely matches the entered identifier. In performing this determination, the present invention employs a confusion matrix, which is an arrangement of probabilities that indicate the likelihood that a given character in a particular character position of the reference identifier would be recognized by the recognizer as a character in the corresponding character position of the recognized identifier. This determination yields an identifier recognition probability for every reference identifier, and the present invention selects the reference identifier with the highest identifier recognition probability as most likely corresponding to the spoken identifier. The invention is also provided with the capability of improving the recognition accuracy of the confusion matrix by eliminating from consideration the most often confused characters.
    • 一种用于识别由用户输入的标识符的方法和装置。 呼叫者通过电话手机输入预定的标识符。 表示输入的标识符的信号被发送到远程识别器,远程识别器通过产生旨在匹配输入的标识符的识别的输出来响应信号。 本发明将该识别的标识符与有效参考标识符的列表进行比较,以确定这些参考标识符中的哪一个最可能与输入的标识符匹配。 在执行该确定时,本发明采用混淆矩阵,其是概率排列,其指示参考标识符的特定字符位置中的给定字符将被识别器识别为对应字符位置中的字符的可能性 的识别标识符。 该确定对于每个参考标识符产生标识符识别概率,并且本发明选择具有最高标识符识别概率的参考标识符,其最可能对应于语音标识符。 本发明还具有通过消除考虑最常见的混淆字符来提高混淆矩阵的识别精度的能力。
