X-CUBE-VS4A is the first software package to bring Alexa Voice Service (AVS) to our microcontrollers (MCU). Today, we associate voice services from Amazon, Apple, or Google with smart speakers and if these devices are new and successful, they often look similar. They adopt a cylindrical shape, they are tethered to a wall socket and can get so hot that they can possibly scar certain wood surfaces. This design homogeneity often stems from the use of a beefy application processor that connects to cloud services and processes information, but limits what engineers can actually create. X-CUBE-VS4A is thus a significant breakthrough because it brings AVS to more portable applications to open designers to a whole new type of smart devices…
