Abstract
A voice-interaction device includes a plurality of input and output components configured to facilitate interaction between the voice-interaction device and a target user. The plurality of input and output components may include a microphone configured to sense sound and generate an audio input signal, a speaker configured to output an audio signal to the target user, and an input component configured to sense at least one non-audible interaction from the target user. A context controller monitors the plurality of input and output components and determines a current use context. A virtual assistant module facilitates voice communications between the voice-interaction device and the target user and configures one or more of the input and output components in response to the current use context. The current use context may include whisper detection, target user proximity, gaze direction tracking and other use contexts.
