Throughout this chapter, we have focused on speech. We started by looking at how we can convert spoken audio to text and text to spoken audio. Using this, we modified our LUIS implementation so that we can say commands and have conversations with the smart-house application. From there, we moved on to see how we can identify a person speaking using the Speaker Recognition API. Using the same API, we also learned how to verify that a person is who they claim to be. We briefly looked at the core functionality of the Custom Speech Service. Finally, we briefly covered an introduction to the Translator Speech API.

In the following chapter, we will move back to textual APIs, where we will learn how to explore and analyze text in different ways.
