All Implemented Interfaces:

SpeechEventDispatcher

public class TextSynthesizer
extends BaseSynthesizer

Supports a simple text-output-only JSAPI 1.0 Synthesizer. Intended for demonstration purposes for those developing JSAPI implementations. It may also be useful to developers who want a JSAPI synthesizer that doesn't produce any noise.
