Abstract
A voice-controlled device, such as a virtual assistant, has keyword processing functionality 200 that operates to identify voice activity in environmental sound information, and to then process the environmental sound information when voice activity is detected to extract one or more audio features and can be used by a neural network to identify one or more keywords. The keyword processing functionality is controlled to not process or to store any sound information prior to voice activity being detected.
