Sphinx-4General Information about Sphinx-4 Introduction Sphinx-4 is a state-of-the-art speech recognition system written entirely in the JavaTM programming language. It was created via a joint collaboration between the Sphinx group at Carnegie Mellon University, Sun Microsystems Laboratories, Mitsubishi Electric Research Labs (MERL), and Hewlett Packard (HP), with contributions from the University of California at Santa Cruz (UCSC) and the Massachusetts Institute of Technology (MIT). Sphinx-4 started out as a port of Sphinx-3 to the Java programming language, but evolved into a recognizer designed to be much more flexible than Sphinx-3, thus becoming an excellent platform for speech research. http://cmusphinx.sourceforge.net/sphinx4/#what_is_sphinx4
但是 Java Speech API 之提供了相应的接口，具体实现有很多，可以使用免费的 FreeTTS:
