Embodiment Construction

[0010] In the following description of examples, reference is made to the accompanying drawings that show, by way of illustration, specific examples that may be implemented. It is to be understood that other examples may be utilized and structural changes may be made without departing from the scope of the various examples.

[0011] This involves systems and processes for selectively processing and responding to voice user input. In one example process, audio input including spoken user input may be received at a user device. The voice user input can be recognized by recognizing the start point and the end point of the voice user input. Whether the voice user input is intended for a virtual assistant running on the user device and whether the virtual assistant should respond to the voice user input can be determined based on the context information. The determination can be made using a rule-based system or a probabilistic (eg machine learning) system. If it is determined t...

Abstract

The invention relates to reducing the need for manual start / end-pointing and trigger phrases. 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.

Description

technical field [0001] This relates generally to speech processing, and more specifically to selectively processing speech user input using contextual data. Background technique [0002] Intelligent automated assistants (or virtual assistants) provide intuitive interactions between users and electronics. These assistants allow users to interact with devices or systems using natural language, in the form of voice and / or text. For example, a user can access services of an electronic device by providing voice user input to a virtual assistant associated with the electronic device. Virtual assistants can interpret user intent from voice user input and implement user intent into tasks. Tasks can then be performed by performing one or more functions of the electronic device and relevant output can be returned to the user in natural speech. [0003] In order for the virtual assistant to properly process and respond to the voice user input, the virtual assistant can first identif...
