Some further comments: Every effort has been made to ensure that Festival does not contain any violation of intellectual property rights through disclosure of trade secrets, copyright or patent violation. Considerable time and effort has been spent to ensure that this is the case. However, especially with patent problems, it is not always within our control to know what has or has not been restricted. If you do suspect that some part of Festival cannot be legally distributed please please inform us so that an alternative may be sought. Festival is only useful if it is truly free to distribute. As of 1.4.0 the core distribution (and speech tools) is free. Unlike previous versions which had a commercial restriction. You are free to incorporate Festival in commercial (and of course non-commercial systems), without any further communication or licence from us. However if you are seriously using Festival within a commercial application we would like to know, both so we know we are contributing and so we can keep you informed of future developments. Also if you require maintenance, support or wish us to provide consultancy feel free to contact us. The voices however aren't all free. At present the US voices, kal and ked are free. Our British voices are free themselves but they use OALD which is restricted for non-commercial use. Our Spanish voice is also so restricted. Note other modules that festival supports e.g MBROLA and OGI extensions, may have different licencing please take care when using the system to understand what you are actually using. -------------------------------------------------- A number of individual files in the system fall under a different copyright from the above. All however are termed "free software" but most people. ./src/arch/festival/tcl.c * Copyright (C)1997 Jacques H. de Villiers <jacques@cse.ogi.edu> * Copyright (C)1997 Center for Spoken Language Understanding, * Oregon Graduate Institute of Science & Technology See conditions in file.
