English G2P token classification model
This is a non-autoregressive model for English grapheme-to-phoneme (G2P) conversion based on BERT architecture. It predicts phonemes in CMU format. Initial data was built using CMUdict v0.07
Intended uses & limitations
The input is expected to contain english words consisting of latin letters and apostrophe, all letters separated by space.

Note that the correct output tags are in the third column, input is in the second column.
Tags correspond to input letters in a one-to-one fashion. If you remove <DELETE>
tag, and replace _
with space, you should get CMU-like transcription.
How to use for TTS
See this script to run TTS directly from CMU phonemes.
