    • A method and system for allowing a user to interface to an interactive voice response system via natural language commands. The system plays a prompt that initiates user interaction. In certain embodiments, the system detects initial user speech, wherein the initial user speech begins during the prompt or during a silence after the prompt. Then, the system determines whether the user speech restarts (second user speech) within a predetermined time period, wherein the predetermined time period is dependent upon whether the initial user speech began during the prompt or during the silence. If the user speech does restart, then the system uses the second user speech for recognition purposes. If the user speech does not restart, then the system uses the initial user speech for recognition purposes.
    • 一种用于允许用户通过自然语言命令与交互式语音响应系统接口的方法和系统。 系统发出启动用户交互的提示。 在某些实施例中,系统检测初始用户语音,其中初始用户语音在提示期间或在提示之后的静音期间开始。 然后,系统确定用户语音是否在预定时间段内重新开始(第二用户语音),其中预定时间段取决于初始用户语音是在开始时还是在静音期间开始。 如果用户语音确实重新启动,则系统使用第二用户语音进行识别。 如果用户语音不重新启动,则系统使用初始用户语音进行识别。
