    摘要: A method for operating a voice trigger is provided. In some implementations, the method is performed at an electronic device including one or more processors and memory storing instructions for execution by the one or more processors. The method includes receiving a sound input. The sound input may correspond to a spoken word or phrase, or a portion thereof. The method includes determining whether at least a portion of the sound input corresponds to a predetermined type of sound, such as a human voice. The method includes, upon a determination that at least a portion of the sound input corresponds to the predetermined type, determining whether the sound input includes predetermined content, such as a predetermined trigger word or phrase. The method also includes, upon a determination that the sound input includes the predetermined content, initiating a speech-based service, such as a voice-based digital assistant.

    摘要: The present disclosure generally relates to using voice interaction to access call functionality of a companion device. In an example process, a user utterance is received. Based on the user utterance and contextual information, the process causes a server to determine a user intent corresponding to the user utterance. The contextual information is based on a signal received from the companion device. In accordance with the user intent corresponding to an actionable intent of answering the incoming call, a command is received. Based on the command, instructions are provided to the companion device, which cause the companion device to answer the incoming call and provide audio data of the answered incoming call. Audio is outputted according to the audio data of the answered incoming call.

    摘要: 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.
