This chapter is devoted to audio classification using the Edge Impulse low code platform. You take a brief tour of how audio can be captured using a digital microcontroller, which features constitute the state-of-the-art descriptors for speech analysis, and how to detect specific words from our board. As a reference project for this chapter, we build a clone of the widely used voice assistant devicesVoice assistant devices (Alexa, Siri, Google Home), which are limited to their activation mechanism. Instead of “OK Google,” you can wake up your Arduino board with the “Hey Arduino” vocal command.

This chapter is devoted to audio classification using the Edge Impulse low code platform. You take a brief tour of how audio can be captured using a digital microcontroller, which features constitute the state-of-the-art descriptors for speech analysis, and how to detect specific words from our board. As a reference project for this chapter, we build a clone of the widely used voice assistant devicesVoice assistant devices (Alexa, Siri, Google Home), which are limited to their activation mechanism. Instead of “OK Google,” you can wake up your Arduino board with the “Hey Arduino” vocal command.
