There needs of course to be a c++ compiler together with the usual development environment and libraries. Also required is java at least version 7, and javac at least version 6, both of which are needed in the front-end and the Stanford parser. Perl: Further required is Perl, which is used in the included text normalization software (written mainly with bash and perl scripts). For the synthesizer Perl is only used in one component named normalize.pl (~/lti_source/trunk/synthesizer/bin/normalize.pl) but requires a few packages (see the header of normalize.pl) that may not be part of the standard distribution but can be obtained by the ctan mechanism. In particular there is package named Roman, and another named Lingua::EN::Numbers::Years, which may or may not be in the standard distribution. The documentation of how to obtain these components can easily be found at http://www.cpan.org/ where there is a direct link named "Installing Perl Modules" SoX: Also required is the SoX software, which should be standard in the linux distribution, and the program uni2ascii, used in the text normalization. Further, to make mp3 output, the linux software called lame needs to be installed. Octave: For installation of the software, there is one step that requires the software octave to be installed.
