In the case of speech research and development the dominant tools today are computer programs. In this article we present an overview of key technical approaches and features that are prevalent today. We restrict the discussion to software intended to support R D as opposed to software for commercial applications of speech processing. For example we ignore DSP programming which is discussed in the previous article . Also we concentrate on software intended to support the special 1999 by CRC Press LLC ities of .
