23:45 🔗 Lord_Nigh has joined #internetarchive
23:46 🔗 Lord_Nigh question: the description at https://archive.org/details/dectalk has several errors in it. how can i go about correcting those?
23:46 🔗 Lord_Nigh "DECtalk was a speech synthesizer and text-to-speech technology developed by Digital Equipment Corporation in 1984, based largely on the work of Dennis Klatt at MIT, whose source-filter algorithm was variously known as KlattTalk or MITalk."
23:49 🔗 Lord_Nigh In reality DECtalk is derived from Jonathan Allen, Sharon Hunnicutt and Dennis Klatt's work on MITalk at MIT (ln: which I'd REALLY LOVE to see the source code of). Klatt first took a simplified? version of MITalk commercial as "KlattTalk" which was a program which could run on a 1981/82 ibm pc, and DEC very quickly bought an exclusive license to this program and ported it to the 68000, and vastly improving it at
23:49 🔗 Lord_Nigh the time.
23:49 🔗 Lord_Nigh this became the DTC-01
23:50 🔗 JAA From https://archive.org/details/softwarelibrary%26tab=collection&tab=about : "If you'd like to volunteer to help describe and increase knowledge on disks in the Software Library, contact Jason at jscott@archive.org."
23:50 🔗 Lord_Nigh at the same time as the exclusive licensing happened, DEC forbade klatt from making additional contributions publically to KLSYN, which is the synthesis core that both mitalk, klattalk, and dectalk used (the telesensory/speech plus prose 2000/calltext 5010 uses a version of it as well)
23:50 🔗 Lord_Nigh this is why KLSYN has two 'forks': klsyn80 and klysn88, the former being public domain and the latter owned by snsimetrics
23:50 🔗 Lord_Nigh *sensimetrics
23:51 🔗 Lord_Nigh who obtained the rights to it as part of klatt's will after his death in 1988
23:51 🔗 Lord_Nigh (I believe it was DEC who insisted it not be public domain, but am not sure)
23:53 🔗 Lord_Nigh the fact that telesensory/Speech plus was able to use klsyn at all is because they forked klsyn80 (and possibly some of MITalk before DEC licensed that as well?), and i believe dec was not happy about this
23:53 🔗 Lord_Nigh the smithsonian speech synthesis history project has more info
23:55 🔗 Lord_Nigh also bleh i need to fix MAMEs emulation of the dectalk nvram, its not supposed to give an 'NVR Fault' error on startup
23:55 🔗 Lord_Nigh it used to work, regressed a few years ago
