Voice interactions

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.
