As discussed in Chapter 1, Speech on Android Devices, Google Voice Actions are simple interactions in which the user speaks a question or a command and the app responds with an action or a verbal response (or a combination of both).
Note
The following are examples of similar interactions with a simple structure and involving a small number of turns:
Example 1
User: BBC News
App: (launches BBC News)
Example 2
App: What is your query?
User: What is the capital of France?
App: (returns web pages about Paris and France)
The interactions are simple in the following ways:
Limited dialog management: The interactions consist of at most two or three turns.
Limited spoken language understanding: The user is restricted to inputs consisting of single words or phrases, such as the name of a website or of an app, or a stretch of text that can be handled by the Google search engine.
