(I originally sent a message through the contact form; however, I was advised to email this address instead. Apologies for any duplicate or redundant messages.) To the developers of Voice.ai: I have recently downloaded and installed the Voice.ai Software on my PC. I have also discovered that the Voice.ai software includes a software component licensed under the Lesser GNU General Public License version 2.1 (LGPL v2.1) - more specifically, libgcrypt within VoiceAILib.dll. In accordance with the LGPL v2.1, I am requesting a copy of the libgcrypt source code plus the source code of VoiceAILib.dll and of any other components, tools, and/or scripts necessary to reproduce a working executable with my own version of libgcrypt. Your requirement to fulfill this request is explained in Section 6 of the LGPL v2.1 text: As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) Sections 8 and 9 of the LGPL v2.1 explain the importance of complying with these requirements: You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. In regard to any potential conflicts between this request and any End-User License Agreements or Terms of Service agreements provided by Voice.ai, the LGPL v2.1 text states in Section 10: Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. For reference, the full text of the LGPL v2.1 may be found on the Free Software Foundation's website at https://www.gnu.org/licenses/old-licenses/lgpl-2.1.en.html. The website for the original libgcrypt software may be found at https://gnupg.org/software/libgcrypt/index.html. Source code can be delivered in any reasonable format: a simple .zip file would suffice. Thank you for your time.
