In this section, we will discuss keyword recognition in an audio sample using the Pico. This is similar to the voice assistant devices that are designed and marketed by tech giants such as Amazon Echo, Google Home, and others that respond to an activation keyword such as "Hey Alexa." We will be making use of Edge Impulse (https://edgeimpulse.com) to work on this example. Sign up for a developer account on Edge Impulse to work along with this example.
