docx2txt is a tool that attempts to generate equivalent text files from Microsoft .docx documents, preserving some formatting and document information (which MS text conversion drops) along with appropriate character conversions for a good (ASCII) text experience. It is a platform independent solution consisting of (core) Perl and (wrapper) Unix/Windows shell scripts and a configuration file to control the output text appearance to fair extent. It can very conveniently be used to build a Web based docx document conversion service. Some Makefiles and Windows batch files are provided for easy installation of the scripts. With unzippers like CakeCmd that can deal with corrupt Zip archives, this tool can extract text from corrupt docx documents in many cases, where MS word processor fails to even open them.
VoiceXML::Client is a library that provides Perl programs with the ability to act as a user agent that fetches Voice Extensible Markup Language (VoiceXML) documents, parses them, and then executes the instructions therein by playing prompts and collecting user DTMF input/voice recordings through a handle to some type of telephone or other device interface. VoiceXML::Client's focus is on the client side. The XML documents are generated by a distinct process of your choice, unrelated to the library.
Perl text2html is an HTML 4.01/CSS2 project that converts pure plain text files into very informative and professional looking HTML documentation pages. The text files require no markup whatsoever; just naturally written text. This utility predates the now similar Python-based asciidoc.
