Abstract:

Functionality is described herein for recognizing speakers in an energy-efficient manner. The functionality employs a heterogeneous architecture that comprises at least a first processing unit and a second processing unit. The first processing unit handles a first set of audio processing tasks (associated with the detection of speech) while the second processing unit handles a second set of audio processing tasks (associated with the identification of speakers), where the first set of tasks consumes less power than the second set of tasks. The functionality also provides unobtrusive techniques for collecting audio segments for training purposes. The functionality also encompasses new applications which may be invoked in response to the recognition of speakers.
