How does the caller interact with the Java application?

The caller can interact with the application in two ways:

Free form key or voice input
Structured menu input using key presses (DTMF), or speech recognition, or both.

There are two attribute classes that are used in conjunction with the Call.playAndGetInput() method to facilitate this: MenuAttributes and InputAttributes

To record the caller’s speech and store it as a voice segment, you use the Call.record() method.

For more information about speech recognition see Speech Recognition.
