Lingose

中文

Lingose is an offline English lexicon for Python. Look up pronunciations, word structure and English–Chinese meanings, browse vocabulary lists, or add pronunciation marks to English text.

Requires Python 3.11+. Queries work offline with no third-party runtime dependencies.

The IPSM Approach

The IPSM Approach (Integrated Pronunciation, Spelling and Meaning Approach) connects a word's pronunciation, spelling and meaning to support vocabulary learning. It brings together IPS, which marks pronunciation on the spelling; ISM, which divides a word into morphemes to show its structure; and IPM, which explores links between sound and meaning through listening and speaking. Lingose provides IPA, IPS, ISM, IPSM derived from IPS and ISM, meanings and vocabulary categories for use with the approach.

Install

After 0.3.0 is published to PyPI, install it with:

python -m pip install lingose==0.3.0

Look up a word

Lingose offers four ways to represent a word: IPA for phonetic transcription, IPS for pronunciation marks on its spelling, ISM for morpheme divisions, and IPSM for pronunciation marks combined with those divisions.

import lingose

print(lingose.ipa("apple"))            # ['æpəl']
print(lingose.ips("running"))          # ['rûnning']
print(lingose.ism("running"))          # runn-ing
print(lingose.ipsm("running"))         # ['rûnn-ing']
print(lingose.root_lemma("running"))   # run
print(lingose.meaning("apple", lang="zh"))

The uppercase names IPA(), IPS(), ISM() and IPSM() remain available; the lowercase names are aliases with identical behavior.

Use lang="en" for English meanings. Unavailable pronunciations return []; unavailable meanings and ISM return None.

lookup(word) returns nine fixed keys: word, ipa, ips, ism, ipsm, root_lemma, rank, meaning and labels. Pronunciation fields are single strings or None; meaning always has en and zh. Unknown words keep the input word; other scalars and both meanings are None, with labels=[].

result = lingose.lookup("Apple")
print(result["word"])  # Apple
print(result["ipa"])   # æpəl
print(result["meaning"]["en"])

Annotate text

print(lingose.annotate_ips("Abandon the book."))
# Åbando̊n ṫhe̊ book.

print(lingose.annotate_ips("Abandon the book.", skip_top=1000))
# Åbando̊n the book.

Text keeps its capitalization, spacing and punctuation. Increase skip_top to leave more common words and their inflections unchanged; the default is 0. Words that cannot be converted appear in brackets, such as [unknownword].

Vocabulary lists

print(lingose.kind("apple", "CET4"))   # True
print(lingose.kind_list("CET4")[:10])  # First ten words in the list
print(lingose.labels())               # All available categories

Categories include CET4, CET6, IELTS, TOEFL and Oxford vocabulary lists.
