The ivi/VINCI software is a research tool, not a commercial product. We offer it for downloading free of charge in a spirit of sharing and of making the tool available to others who think it might be useful. It must be understood, however, that especially in regard to the VINCI component, we have never had the time or resources to test it thoroughly enough. Though it serves us well, we sometimes encounter errors or even crashes, particularly if the input data departs far enough from what the program expects. We make no claims about its quality and give no warranties. Please accept it for what it is, and use it at your own risk.

We would like to hear about interesting applications, along with suggestions for additions or generalizations to fill gaps that you encounter, but we cannot undertake to respond to questions or to reports of errors.

There are some differences, largely in regard to those features of ivi which involve close interaction with the environment (e.g. ivi driver programs, changes of window size, ...) Details are apt to vary with the whims of the operating systems designers. We will provide some information in the Environment page.

The following versions of ivi/VINCI are executable files in tar form. Your browser may un-tar them automatically; otherwise you will have to call tar to do so (tar xvf filename).

The programs have been compiled with library functions statically embedded to avoid problems in locating library files in environments which store them in a non-standard way.

Updated versions were installed on 4th June 2007. (The version can be identified by executing the ivi IDentify command, which gives the date of compilation as 1st June 2007 in all three cases.) This version includes the implementation of frequency variation attachments for terminal nodes; a command to vary the frequency attached to lexicon entries; a new version of the RM command which uninstall language description files; and some minor improvements and corrections. Manual pages will be updated as soon as possible.

New versions were installed here on 1st October 2007. (The ID command gives 28th or 29th September.) This fixes a bug which prevented lexical transformations from being applied.
