In-Call Virtual Assistants

摘要

Techniques for providing virtual assistants to assist users during a voice communication between the users. For instance, a first user operating a device may establish a voice communication with respective devices of one or more additional users, such as with a device of a second user. For instance, the first user may utilize her device to place a telephone call to the device of the second user. A virtual assistant may also join the call and, upon invocation by a user on the call, may identify voice commands from the call and may perform corresponding tasks for the users in response.

主权项

1. A system comprising:
one or more processors; and one or more computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:
receiving, from a first user during a voice communication established between a device of the first user and a device of a second user, a request to invoke a virtual assistant during the voice communication, the virtual assistant performing speech recognition on an audio signal representing audio of the voice communication between the first and second users upon invocation, the performing of the speech recognition for identifying a voice command from at least one of the first user or the second user;performing speech recognition on the audio signal representing the voice communication between the first and second users for identifying a voice command at least partly in response to receiving the request;identifying a voice command from the audio of the voice communication between the first and second users responsive to the performing of the speech recognition;performing a task corresponding to the voice command at least partly in response to the identifying of the voice command; andproviding an output audio signal to at least one of the device of the first user or the device of the second user during the voice communication, the output audio signal configured to cause audible output associated with the performing of the task on at least one of the device of the user or the device of the second user.
