Are the MITalk/KlatTalk recordings you shared from the speech synthesis
collection created by Dennis Klat? They sound familiar to my ears.
When I  shared the first generation dectalk.mp3 audio, I was not aware  that
the first generation file was a prank.

The early DECtalk did not sound that terrible. The MIT MITalk system from
1979 is recognizable in this recording as the DECtalk ancestor it is:


The Klattalk system from 1983 was the immediate predecessor of DECtalk and
is indistinguishable from the early DECtalk as can be heard in this
