[DECtalk] why is dectalk's alphabet so strange?

[Blake Roberts]

Alex, Are you saying that  Dectalk is based off another synthesizer's
dictionary? That explains to me why the phonetic dictionary of Dectalk and
the one used by TTS company Cepstral are  similar.

Looks like DEC was loosely based on the CMU dictionary... there's
definitely some crossover somewhere...

It's worth noting that between DEC 4.3 and 4.64, and FonixTalk
thereafter, there were some trivial changes, both with auditory
phonemes and what is accepted in brackets of phonemic text. For
example dashes choke FonixTalk, but work fine in 4.3. You can still
use underscores or commas to insert pauses, durations are optional as
always.
