    • Systems and processes for selectively processing and responding to a spoken user input are provided. In one example, audio input containing a spoken user input can be received at a user device. The spoken user input can be identified from the audio input by identifying start and end-points of the spoken user input. It can be determined whether or not the spoken user input was intended for a virtual assistant based on contextual information. The determination can be made using a rule-based system or a probabilistic system. If it is determined that the spoken user input was intended for the virtual assistant, the spoken user input can be processed and an appropriate response can be generated. If it is instead determined that the spoken user input was not intended for the virtual assistant, the spoken user input can be ignored and/or no response can be generated.
    • 提供了用于选择性处理和响应口头用户输入的系统和过程。 在一个示例中,可以在用户设备处接收包含口头用户输入的音频输入。 通过识别说出的用户输入的开始点和结束点,可以从音频输入中识别说出的用户输入。 可以基于上下文信息来确定口头用户输入是否打算用于虚拟助理。 可以使用基于规则的系统或概率系统进行确定。 如果确定说出的用户输入是针对虚拟助理的,则可以处理说出的用户输入并且可以生成适当的响应。 如果确定说出的用户输入不是针对虚拟助理的,则说出的用户输入可以被忽略和/或不能产生响应。
