Phonemizer module for various languages.

This is wrapper module of https://github.com/bootphon/phonemizer. You can define various g2p modules by specifying options for phonemizer.

See available options:

espnet2.text.phoneme_tokenizer.pyopenjtalk_g2p_prosody(text: str, drop_unvoiced_vowels: bool = True) → List[str]

Extract phoneme + prosoody symbol sequence from input full-context labels.

The algorithm is based on Prosodic features control by symbols as input of sequence-to-sequence acoustic modeling for neural TTS with some r9y9’s tweaks.

Parameters

• text (str) – Input text.

• drop_unvoiced_vowels (bool) – whether to drop unvoiced vowels.

Returns

List of phoneme + prosody symbols.

Return type

List[str]

Examples

>>> from espnet2.text.phoneme_tokenizer import pyopenjtalk_g2p_prosody
>>> pyopenjtalk_g2p_prosody("こんにちは。")
['^', 'k', 'o', '[', 'N', 'n', 'i', 'ch', 'i', 'w', 'a', '$']
