Abstract
Methods, systems, and apparatuses are described for context-based speech processing. A current context may be determined. A subset of trigger words or phrases may be selected, from a plurality of trigger words, as trigger words that a computing device is configured to recognize in the determined current context. The computing device may be controlled to listen for only the subset of trigger words during speech recognition.
Claims39
A method comprising:
- determining, by a computing device, information indicating content being output by another device in an environment associated with the computing device;
- performing speech recognition using a subset of trigger commands, of a plurality of trigger commands, that are based on the indicated content;
- and
- causing, based on a received audio input that comprises at least one trigger command of the subset of trigger commands, performance of an action.
A method comprising:
- determining, by a computing device in an environment comprising one or more devices, based on a time of day and audio output by another device in the environment, a set of trigger commands, wherein the set of trigger commands comprises fewer than a quantity of trigger commands in a plurality of trigger commands, and wherein at least one trigger command, of the set of trigger commands, is associated with the another device;
- and
- causing performance of speech recognition based on the set of trigger commands.
An apparatus comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
- determine information indicating content being output by another device in an environment associated with the apparatus;
- perform speech recognition using a subset of trigger commands, of a plurality of trigger commands, that are based on the indicated content;
- and
- cause, based on a received audio input that comprises at least one trigger command of the subset of trigger commands, performance of an action.
An apparatus comprising:
- one or more processors;
- and
- a memory storing computer-readable instructions that, when executed by the one or more processors, cause the apparatus to:
- determine, in an environment comprising one or more devices, based on time of day and audio output by another device, a set of trigger commands, wherein the set of trigger commands comprises fewer than a quantity of trigger commands in a plurality of trigger commands, and wherein at least one trigger command, of the set of trigger commands, is associated with the another device;
- and
- cause performance of speech recognition based on the set of trigger commands.
A non-transitory computer-readable medium storing instructions that, when executed, configure a computing device to:
- determine information indicating content being output by another device in an environment associated with the computing device;
- perform speech recognition using a subset of trigger commands, of a plurality of trigger commands, that are based on the indicated content;
- and
- cause, based on a received audio input that comprises at least one trigger command of the subset of trigger commands, performance of an action.

- and
- cause performance of speech recognition based on the set of trigger commands.
