Mapping an audio utterance to an action using a classifier

A computer-readable storage medium, having stored thereon program instructions that, upon execution by a computing device, cause the computing device to perform a set of operations comprising:

• receiving an audio utterance;
• determining a text string based on the utterance;
• determining a string-feature vector based on the text string;
• receiving sensor data;
• determining a sensor-feature vector based on the sensor data;
• selecting a target classifier from a set of classifiers, wherein the target classifier is selected based on a determination that a string-feature criteria of the target classifier corresponds to at least one string-feature of the string-feature vector and a sensor-feature criteria of the target classifier corresponds to at least one sensor-feature in the sensor-feature vector;
• and
• initiating a target action that corresponds to the target classifier.

A computing device comprising:

• a user interface having an input component;
• a processor;
• and
• a computer-readable storage medium, having stored thereon program instructions that, upon execution by the processor, cause the computing device to perform a set of operations comprising:
• receiving an audio utterance via the input component;
• determining a text string based on the utterance;
• determining a string-feature vector based on the text string;
• selecting a target classifier from a set of classifiers, wherein the target classifier is selected based on a determination that a string-feature criteria of the target classifier corresponds to at least one string-feature of the string-feature vector;
• and
• initiating a target action that corresponds to the target classifier.

A method, comprising:

• receiving, by a computing device, an audio utterance;
• determining a text string based on the utterance;
• determining a string-feature vector based on the text string;
• receiving sensor data;
• determining a sensor-feature vector based on the sensor data;
• determining an identified action;
• and
• generating a classifier, wherein the classifier has a string-feature criteria that corresponds to at least one string-feature in the string-feature vector, has a sensor-feature criteria that corresponds to at least one sensor-feature in the sensor-feature vector, and corresponds to the identified action.
