I have also been trying to get in touch with the license holders of decTalk but with no success. If you find anything out, please let me know. I am particularly interested in sapi5 versions of decTalk 4.41 4.51 and 4.60.

Subject: [DECtalk] DECtalk TTS licensing

Hello everybody.
I am looking for an opportunity to license DECtalk software technology to develop a cross-platform multilingual speech synthesizer compatible with screen readers. First of all, on Windows and Android, and in the future, possibly Linux and macOS.
Unfortunately, I ran into the problem of being unable to contact the copyright holders of DECtalk.
SpeechFX, Inc. website does not work (speechfxinc.com), and I am not receiving a response to message sent to the email that was previously indicated on this site (sales at speechfxinc.com).
I tried to contact Roger Dudley personally, who is the CEO of SpeechFX, but his addresses, which I discovered in the public sources, no longer exist.
I know that there is an available software implementation of DECtalk and even its source code is publicly available, but these are all illegal versions. I want to officially license DECtalk for my non-commercial project.
I will be very grateful if someone can suggest how else I can contact the copyright holders of DECtalk.
If you have any information, but you do not want to publish it publicly, then you can write to me directly at nikitamailings at yandex.com
Best regards, Nikita.
