Technically, making a smart speaker machine is easy. We need a microphone and speaker for input and output audio. We also need an audio processing module and machine learning engine to manipulate speech audio and interpret speech commands.
In this section, we'll learn about one of the platforms for a smart speaker machine--ReSpeaker from SeeedStudio. We can use it with IoT boards such as Arduino and Raspberry Pi to perform automation tasks. You can get this module from SeeedStudio at https://www.seeedstudio.com/ReSpeaker-Core-Based-On-MT7688-and-OpenWRT-p-2716.html. Here it is:
The ReSpeaker board uses the AI7688 Wi-Fi module, running the OpenWrt OS. To implement additional automation tasks, ReSpeaker uses the ATMega32U4 as its coprocessor and WM8960 for its codec engine. You can see the ReSpeaker core board layout in the following figure:
