Publications

Software

• Hephaestus, a collection of open source projects related to all aspects of speech distributed by CMU
• Flite a small fast run-time speech synthesis engine. Yet another addition to the suite for free software tools and engines for speech synthesis.
  • CMU Flite home page
• The Festvox project: documentation, scripts, tools and examples of building new synthetic voices in the Festival Speech Synthesis System. This contains enough basic information, scripts, autolabellers and walkthroughs for an interested person to build a complete new synthetic voice for English and other languages.

• NSW: non-standard words: Standardizing how text is normalized using the techniques developed at the Johns Hopkins University Summer Workshop 1999 project on Normalization of Non-Standard Words
  • http://festvox.org/nsw/
• The Festival Speech Synthesis System, is a general purpose text to speech system offering both a development environment for synthesis techniques and a robust multi-lingual text to speech system. Festival offers a Scheme-based interpreter for high-level control of the C++ objects that do most of the real work. Work in Festival is currently concentrated on using statistical language processing techniques for text analysis, e.g. part of speech tagging, tokenization, superficial syntactic parsing etc. See here for demos. A full source distribution for most Unix systems (and Windows), is available for free for commercial and non-commercial use under an X11-type licence.
  • Festival home page
• CHATR: a generic speech synthesis system. This system developed at ATR offers multi-lingual synthesis for English and Japanese (with Korean and German closely following). Its main waveform synthesis technique uses non-uniform unit selection from speech databases using acoustic and prosodic features. It can build a voice from any phonetically labelled database. The system allows real-time text to speech, as well as offering a development environment for investigating new speech synthesis techniques. The system is portable and has been tested on seven different common Unix platforms.
• ASTL: This software offers a situation theoretic language which can be used to describe many contemporary semantic theories such as DRT, Dynamic Logic, Montague Grammar and Situation Semantics. It is especially good with donkeys. This is written in Common Lisp, and includes some small examples.
  • astl-0.4.tar.gz
• GNU Tools for Minix 386: This (now old code) provided the first ports of gcc, emacs and gdb to the cheap, though not free, Unix-like system Minix (but does include full sources). Linux was first developed using this compiler. This work has been superseded by the more substantial free Unix systems Linux, FreeBSD, NetBSD and OpenBSD.
  • Minix GCC
• MAP-3.1: a morphological analyser and lexicon system. This was developed as part of the UK ALVEY Natural Language Tools project but is now available separately without licence. This is written in Common Lisp and allows users to design, test and use practical lexicons and morphological analysers. It includes a substantial manual for both the non-programmer and programmer who wishes to embed this system in larger natural language systems. A substantial English dictionary (8000 stems) and morphological analyser is included.
