| 460r008.zip | DECtalk 4.60 Revision 8 | This is the version of DECtalk that shipped with the Window Eyes screen reader, which was developed by GW Micro. This version of DECtalk was specifically patched for GW Micro on June 13, 2003. |
| 462.zip | DECtalk 4.62 | This is essentially DECtalk 4.61 with some updates, and it was a candidate for inclusion with Window Eyes. The archive also includes an old version of the vocal tract model from the mid-90s. |
| 463.zip | DECtalk 4.63 | This archive happens to include prebuilt demo and SAPI5 installation media. |
| Ad 2.zip | DECtalk 5.0 Beta | The code in this archive is for an erly beta of DECtalk 5.0, and it is most likely an advanced development (ad) branch. Most of the synthesizer code appears to be from late 2003, and everything else in the archive is from erly 2004. |
| ad-new.zip | DECtalk 5.1 and 4.64 | DECtalk 5.1 appears to be a beta of what ultimately became FonixTalk. This archive also includes various internal documents and published papers that were consulted during development of various languages, such as Chinese and Japanese. |
| hebrew_mac_2016_09_04_latest.zip | MacOS/iOS port of DECtalk 5.0 | This version of DECtalk was used in TropeTrainer, which was a Hebrew cantoring product that was developed by Tom Buchler. |
| microdectalk.zip | DECtalk Express firmware that was modified to run on devices such as the Epson S1C33 | This archive doesn't include any project files, and the included source code is most likely based on DECtalk 4.2. Some parts of the code suggest a voicemail system was one of the theoretical applications for this project. |
| parser.zip | A version of the text preprocessor (circa 1997) | |
| product.460.zip | DECtalk 4.60 Revision 11 | This is the final revision of DECtalk 4.60. Some source code comments hint at HLsyn intigration, however it isn't used or included at this stage of development. This version of the synthesizer was apparently used in the latest version of Blaxxun Contact, which was a VRML plugin for web browsers. |
| tools.zip | Various tools that were used during DECtalk development, such as the data files and compilers for the letter to sound rules and phonemes. More phoneme data can be found in other archives. | This archive also includes a Unix port of an early revision of DECtalk 4.51. |
