Bundled g2p-en 2.1.0 (Kyubyong Park and Jongseok Kim).
Upstream: https://github.com/Kyubyong/g2p
License: Apache-2.0; see LICENSE.txt.

piper-plus bundles the original inference source, checkpoint and homograph
table under private package namespaces. Data and license are byte-identical
to the pinned PyPI wheel. g2p.py uses a raw regex literal to avoid Python's
invalid-escape SyntaxWarning; its regex value and pronunciation are unchanged.
Distance and its GPL code are not included. The
upstream distribution's unused Distance requirement is not adopted.
NumPy, NLTK and inflect remain explicit dependencies. NLTK corpus data is
not bundled here; its existing installation and licensing still apply.
expand.py derives from Keith Ito's MIT-licensed Tacotron number normalizer.
Its original copyright/permission notice is retained in TACOTRON-LICENSE.txt.
