ATTRIBUTE-BASED AUDIO CHANNEL ARBITRATION

摘要

A speech-based system includes a local device in a user premises and a remote service that uses the local device to conduct speech dialogs with a user. The local device may also be directed to play audio such as music, audio books, etc. When designating audio for playing by the local device, the remote service may specify that the audio is either background audio or foreground audio. For background audio, the service indicates whether the background audio is mixable. For foreground audio, the service indicates an interrupt behavior. When the local device is playing background audio and receives foreground audio, the background audio is paused, attenuated, or not changed based on the indicated interrupt behavior of the foreground audio and whether the background audio has been designated as being mixable.

1. A device, comprising:
a speaker; a microphone; a network communications interface configured to communicate with a remote speech command service; control logic configured to perform acts comprising:
receiving a command from the speech command service to play audio content;receiving a mixing attribute indicating whether the audio content is mixable;playing the audio content on the speaker at a first volume;receiving a command from the speech command service to play a speech message;receiving an interrupt attribute from the speech command service, wherein the interrupt attribute corresponds to the speech message;playing the speech message on the speaker;attenuating the audio content to a second volume during playing of the speech message if the interrupt attribute indicates an attenuation behavior and the mixable attribute indicates that the audio content is mixable; andpausing the playing of the audio content during playing of the speech message if the interrupt attribute indicates a pause behavior or the mixable attribute indicates that the audio content is not mixable.
