Licensing terms The IFA Spoken Language Corpus contains recorded speech, reading texts, transcriptions, annotations, tabulated data, computer programs, and other works related to these. Copyright (C) 2000, 2001 Dutch Language Union (Nederlandse Taalunie). Contact address: Rob.van.Son@hum.uva.nl (ifa@hum.uva.nl) These works have been designed, recorded, and transcribed under the responsibility of R.J.J.H. van Son with the technical assistence of Ton Wempe and others. This work was made possible by grant nr 355-75-001 of NWO, the Netherlands Organization of Research and a grant from the Stichting Spraaktechnologie. The stories used ('De noordenwind en de zon' and 'Jorinde en Joringel') were taken from "The principles of the International Phonetic Association" (London, 1949, http://www2.arts.gla.ac.uk/IPA/ipa.html) and from the "Kinder- und Hausmaerchen der Brueder Grimm" (1857; http://maerchen.com/) respectively. Both were translated and adaptated by Rob van Son. Note that the original texts of both stories are in the public domain. However, the translations and adaptations are not. All copyrights rest with the Dutch Language Union (Nederlandse Taalunie, URL: http://www.taalunie.org/) unless explicitely stated otherwise. This license is considered part of every component of this work and should be distributed together with the whole or any part of this work.

As it might not be entirely clear how to interpret "source" in the setting of a spoken language corpus, the following is meant as a clarification. Note that this clarification does NOT replace or changes the GNU General Public License or any of its terms. If there remain questions about the terms of the GNU General Public License or their interpretation, please contact the Free Software Foundation or the copyright holder. The GNU General Public License states that the source code for a work indicates the preferred form of the work for making modifications to it. For most projects of the Free Software Foundations this means unobfuscated (that is readable and documented) programming code in "C", "Lisp", or one of several other computer programming languages in ASCII format. This includes header and make files. The source of a single program can consist of a (large) collection of individual files, all of which are needed to recreate the program. Therefore, all files needed to create the program together are considered the source. In the setting of spoken language research, "source" can be interpreted as any form or file-format that allows the easy inspection, analysis, annotation, conversion, and modification by "standard" computer programs. File formats (e.g., AIFC) that can be accessed by the Praat program (www.praat.org), as used for the "Spoken Dutch Corpus" effort (Corpus Gesproken Nederlands), would be examples of "source" in this respect. Of course, any format usable by other freely available programs with equivalent abilities and a recognised "Open Source" license is also included. To be able to productively use speech audio files and their analysis and anotations, it is necessary that the audio files have the required quality, i.e., they should not be compressed and have adequate sample rates and quantization levels. Also, audio files and their annotations are mutually dependend. Each format loses much, or all, of its value when the other is not available. Therefore, associated high-quality audio-files, label files, annotations and transcriptions together should be considered the "source" of any derivation. For database tables, the source can be a documented tab delimited ASCII or UNICODE table or any representation that can be easily imported into a range of databases with Open Source licenses. The aim of the GNU General Public License is to ensure the accessibility of the licensed work to any potential user with minimal effort. Therefore, formats that exclude users (e.g., those prefering to work with MS Windows Software) from accessing the works are not allowed as source. Therefore, excluded as possible "source" are formats that, in any way, restrict the ability to create, access, modify, or use the works (e.g., GIF, some internet streaming formats, CSS encrypted DVD). It doesn't matter whether the restrictions are in the legal use of the format itself, or whether the software needed to actually use it poses restrictions (e.g., MS Office documents which can only be accessed by MS Office programs of the correct version, DVD's that need special readers). When data from this corpus are used in a publication or product, it generally falls under the terms of this license. In this case, the "source" are considered all data derived from the licensed work and used in the product or publication. This includes what is generally considered "raw data", selections, annotations, transcriptions, analysis results, and anything derived from it. All these should be made available as "source". Note that you have to indicate that copyrighted material has been used anyway. Also the names of the contributers/copyright-holders of the original material, and the license terms of your contribution to it have to be mentioned somewhere in the publication or product. However, you do not have to ask permissions, add any co-authors, or split any profits to use material from the corpus. To summarize the "spirit" of this license. If you want to use this corpus, you must be willing to contribute to it everything you learn from it and make it an even more valuable resource. In return, you get the unrestricted use of the corpus and the work of all who contributed to it, and the sole copyright of your own contribution. Yes, contrary to a common misconception, whatever work you have to license under the GNU General Public License remains copyrighted to you, and you alone. And you can sell it for whatever price you want. Provided you make available the source freely available under the GNU General Public License AFTER you sold or distributed it.
