Example

# Download CMU dictionary
wget https://raw.githubusercontent.com/cmusphinx/cmudict/master/cmudict.dict \
  -O "/tmp/example.dict"

# Change formatting to remove numbers from words, comments and save as UTF-8
dict-cli change-formatting \
  "/tmp/example.dict" \
  --deserialization-encoding "ISO-8859-1" \
  --consider-numbers \
  --consider-pronunciation-comments \
  --serialization-encoding "UTF-8"

# Export phoneme set
dict-cli export-phonemes \
  "/tmp/example.dict" \
  "/tmp/example-phoneme-set.txt"
  
# Export vocabulary
dict-cli export-vocabulary \
  "/tmp/example.dict" \
  "/tmp/example-vocabulary.txt"

# Keep first pronunciation for each word and discard the rest
dict-cli select-single-pronunciation \
  "/tmp/example.dict" \
  --mode "first"

# Replace all "ER0" phonemes with "ER"
dict-cli map-symbols-in-pronunciations \
  "/tmp/example.dict" \
  "ER0" "ER"
