Smart audio devices are becoming ubiquitous and their popularity has been skyrocketing. By current standards, a smart audio device is voice-controlled through interaction with an Internet-based intelligent virtual assistant and usually provides access to remote repositories of music or information. This paper focuses on the smart speakers (e.g., Amazon Echo, Google Home, etc.)—the most popular smart audio device. Though they are usually composed of relatively simple audio components, these devices incorporate very sophisticated audio signal processing, a plethora of audio pathways, and functional audio subsystems—posing significant challenge in testing. This paper explores the audio subsystems and pathways found on this type of device and suggests ways to test and validate their functionality and performance.
