Installation

pip install pronunciation-dictionary --user

Usage

from pronunciation_dictionary import load_dict, save_dict, MultiprocessingOptions, DeserializationOptions, SerializationOptions

Example

from pathlib import Path

from pronunciation_dictionary import (DeserializationOptions, 
  MultiprocessingOptions, SerializationOptions, 
  get_phoneme_set, load_dict_from_url, save_dict)

dictionary = load_dict_from_url(
  "https://raw.githubusercontent.com/cmusphinx/cmudict/master/cmudict.dict",
  "ISO-8859-1",
  DeserializationOptions(False, True, True, False),
  MultiprocessingOptions(4, None, 10000)
)

phoneme_set = get_phoneme_set(dictionary)

print(phoneme_set)
# {'Z', 'EY1', 'AH0', 'F', 'AE0', 'UW0', 'CH', 'G', 'V', 'AY1', 'AO2', 'ZH', 'AA1', 'IY1', 'AW0', 'T', 'TH', 'AY2', 'DH', 'S', 'W', 'ER1', 'AA2', 'AE2', 'AE1', 'AW1', 'UW1', 'AH1', 'Y', 'EY2', 'AO0', 'OW2', 'OY2', 'IY2', 'JH', 'N', 'NG', 'P', 'IH2', 'M', 'OW0', 'L', 'UH1', 'IY0', 'EY0', 'HH', 'IH0', 'SH', 'AH2', 'AW2', 'EH2', 'OW1', 'D', 'R', 'IH1', 'AO1', 'B', 'UH2', 'UH0', 'ER0', 'UW2', 'ER2', 'EH0', 'AY0', 'AA0', 'EH1', 'OY1', 'OY0', 'K'}

pronunciations_distmantle = dictionary.get("dismantle")

for pronunciation, weight in pronunciations_distmantle.items():
  print(pronunciation, weight)
# ('D', 'IH0', 'S', 'M', 'AE1', 'N', 'T', 'AH0', 'L') 1.0
# ('D', 'IH0', 'S', 'M', 'AE1', 'N', 'AH0', 'L') 1.0

save_dict(dictionary, Path("/tmp/cmu.dict"), "UTF-8",
          SerializationOptions("DOUBLE-SPACE", False, False))

head /tmp/cmu.dict
# 'bout  B AW1 T
# 'cause  K AH0 Z
# 'course  K AO1 R S
# 'cuse  K Y UW1 Z
# 'em  AH0 M
# 'frisco  F R IH1 S K OW0
# 'gain  G EH1 N
# 'kay  K EY1
# 'm  AH0 M
# 'n  AH0 N

Roadmap

• replace SerializationOptions, DeserializationOptions and MultiprocessingOptions with parameters
• add default parameter values
• add more tests

Running the tests

git clone https://github.com/stefantaubert/pronunciation-dictionary.git
cd pronunciation-dictionary
pip install .
pip install tox
