Two core speech technologies are supported through the Java Speech API: speech synthesis and speech recognition.[1]

Speech synthesis provides the reverse process of producing synthetic speech from text generated by an application, an applet, or a user. It is often referred to as text-to-speech technology.

The major steps in producing speech from text are as follows:

• Structure analysis: Processes the input text to determine where paragraphs, sentences, and other structures start and end. For most languages, punctuation and formatting data are used in this stage.
