US 9,288,594 B1 · Auditory environment recognition

Abstract

A computing device can capture audio data representative of audio content present in a current environment. The captured audio data can be compared with audio models to locate a matching audio model. The matching audio model can be associated with an environment. The current environment can be identified based on the environment associated with the matching audio model. In some embodiments, information about the identified current environment can be provided to at least one application executing on the computing device. The at least one the application can be configured to adjust at least one functional aspect based at least in part upon the determined current environment. In some embodiments, one or more computing tasks performed by the computing device can be improved based on information relating to the identified current environment. These computing tasks can include location refinement, location classification, and speech recognition.
