I understood what is the interaction model of alexa voice service. there are many things like events and directives and how it all work

Overview

A client interacting with the Alexa Voice Service will regularly encounter events/directives that produce competing audio. For instance, a user may ask a question while Alexa is speaking or a previously scheduled alarm may trigger while music is streaming. The rules that govern the prioritization and handling of these inputs and outputs are referred to as the interaction model. In the following sections we’ll cover:

• Interfaces, Directives and Events
• Client Interactions with the Alexa Voice Service
• Voice Request Lifecycle
• Channels
• Testing the Interaction Model

These were all the topics that were to be studied for the complete understanding of all of this.
