espnet-g2p-en 2.1.0.post1

Algorithm

1. Spells out arabic numbers and some currency symbols. (e.g. $200 -> two hundred dollars) (This is borrowed from Keith Ito’s code)

2. Attempts to retrieve the correct pronunciation for homographs based on their POS)

3. Looks up The CMU Pronouncing Dictionary for non-homographs.

4. For OOVs, we predict their pronunciations using our neural net model.
