    • A method for improving the recognition confidence of alphanumeric spoken input, suitable for use in a speech recognition telephony application such as a voice response system. An alphanumeric candidate is determined from the spoken input, which may be the best available representation of the spoken input. Recognition confidence is compared with a preestablished threshold. If the recognition confidence exceeds the threshold, the alphanumeric candidate is selected to represent the spoken input. Otherwise, present call data associated with the spoken input is determined. Call data may include automatic number identification (ANI) information, caller-ID information, and/or dialed number information service (DNIS) information. Information associated with the alphanumeric candidate and information associated with the present call data are correlated in order to select alphanumeric information that best represents the spoken input.
    • 一种用于改善适用于诸如语音响应系统的语音识别电话应用中的字母数字语音输入的识别置信度的方法。 从口头输入确定一个字母数字的候选人,这可能是口头输入的最佳可用表示。 将识别信心与预先建立的阈值进行比较。 如果识别置信度超过阈值,则选择字母数字候选来表示口头输入。 否则,确定与口头输入相关联的当前呼叫数据。 呼叫数据可以包括自动号码识别(ANI)信息,呼叫者ID信息和/或拨号号码信息服务(DNIS)信息。 与字母数字候选者相关联的信息和与当前呼叫数据相关联的信息相关联,以便选择最能代表口头输入的字母数字信息。
