Experts in every field of study depend on specialized tools. 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-...
