The drawings are for purposes of illustrating example embodiments, but it is understood that the inventions are not limited to the arrangements and instrumentality shown in the drawings. In the drawings, identical reference numbers identify at least generally similar elements. To facilitate the discussion of any particular element, the most significant digit or digits of any reference number refers to the Figure in which that element is first introduced. For example, element 103a is first introduced and discussed with reference to
I. Overview
Voice control can be beneficial for a “smart” home having smart appliances and related devices, such as wireless illumination devices, home-automation devices (e.g., thermostats, door locks, etc.), and audio playback devices. In some implementations, networked microphone devices may be used to control smart home devices. A network microphone device will typically include a microphone for receiving voice inputs. The network microphone device can forward voice inputs to a voice assistant service (VAS), such as AMAZON's ALEXA, APPLE's SIRI, MICROSOFT's CORTANA, GOOGLE ASSISTANT, etc. A traditional VAS may be a remote service implemented by cloud servers to process voice inputs. A VAS may process a voice input to determine an intent of the voice input. Based on the response, the network microphone device may cause one or more smart devices to perform an action. For example, the network microphone device may instruct an illumination device to turn on/off based on the response to the instruction from the VAS.
