Abstract
A method is implemented at an electronic device for visually indicating a voice processing state. The electronic device includes at least an array of full color LEDs, one or more microphones and a speaker. The electronic device collects via the one or more microphones audio inputs from an environment in proximity to the electronic device, and processes the audio inputs by identifying and/or responding to voice inputs from a user in the environment. A state of the processing is then determined from among a plurality of predefined voice processing states, and for each of the full color LEDs, a respective predetermined LED illumination specification is determined in association with the determined voice processing state. In accordance with the identified LED illumination specifications of the full color LEDs, the electronic device synchronizes illumination of the array of full color LEDs to provide a visual pattern indicating the determined voice processing state.
