[DECtalk] User dictionary

[Kyle]

OK so I never got the user dictionary figured out, but fortunately I was 
able to edit the US English dictionary, copying similar words and making 
the corrections. I was able to use the same phoneme chart I found on

https://dectalk.github.io/dectalk/idh_ref_3_phonemic_symbols_2.htm

as the first character on the left column is the one the main DECTalk 
dictionary needs to form the correct sound. Stress and syntax symbols 
appear to be the same. I'm not sure what the last two fields do, but 
whenever I copy similar words and paste the lines, correcting only the 
word and its pronunciation, leaving the last two fields alone, then run

dic_us ./dic_us.txt

sudo mv dic_us.dic /opt/dectalk/dic/dtalk_us.dic

the word is immediately pronounced correctly. It would certainly be 
better if I could add entries to a user dictionary and leave the main 
dictionary untouched, but this certainly works for now.
