Anyone who has used Amazon's Echo, Google's Home speaker or even Apple's Siri knows how powerful and convenient speech recognition and voice synthesizing can be. Now imagine if we could add these features, at a smaller scale, to our smart devices? If we could, we would have the ability to speak directly to our coffee pot and tell it to start brewing our coffee in the morning or command the robots that we build.

In this chapter, we will look at how we can add voice recognition and voice synthesizing to any Arduino projects using the MOVI shield. Throughout this chapter, we will learn:

• How to use the MOVI shield for speech recognition
• How to use the MOVI shield for voice synthesizing
• How to create a voice-activated thermometer
