Converts text to phonemes for Piper.
When using eSpeak phonemes, requires an espeak-ng fork with espeak_TextToPhonemesWithTerminator function.
This function allows for Piper to preserve punctuation and detect sentence boundaries.
Pre-compiled releases are available for download.
The piper_phonemize program can be used from the command line:
lib/piper_phonemize -l en-us --espeak-data lib/espeak-ng-data/ <<EOF
This is a test.
This is another test!
