- TTSBackendRegistry class with register(), list_backends(), get_metadata(), create_backend()
- Global registry singleton with register_backend() and create_backend() convenience functions
- Unit tests for registry operations
Moved SupertonicPipeline from abogen/tts_supertonic.py to
abogen/tts_backends/supertonic.py and load_numpy_kpipeline from
abogen/utils.py to abogen/tts_backends/kokoro.py.
Git correctly detects the Supertonic file as a rename (R),
preserving full commit history.
- New package: abogen/tts_backends/
- __init__.py (package marker)
- supertonic.py (SupertonicPipeline, moved from tts_supertonic.py)
- kokoro.py (load_numpy_kpipeline, moved from utils.py)
- abogen/utils.py: re-exports load_numpy_kpipeline for backward compat
- All imports updated to new canonical paths
- Create TTSBackend abstract base class with minimal contract
- Implement KokoroTTSBackend that maintains existing behavior
- Update conversion_runner.py to use new interface
- No behavioral changes, GUI unchanged, no new features
The upstream project moved PyQt code to abogen/pyqt/ subdirectory, making the
original feature commits non-mergeable. This commit re-applies both features
to the new file locations.
Voice Marker feature (<<VOICE:voice_name>> syntax):
- subtitle_utils.py: Added _VOICE_MARKER_PATTERN, _VOICE_MARKER_SEARCH_PATTERN,
validate_voice_name(), split_text_by_voice_markers() (with valid/invalid counts)
- pyqt/conversion.py: Added load_voice_cached(), voice marker pre-processing before
chapter loop, inner voice segment loop wrapping spaCy+TTS block, updated imports
- pyqt/gui.py: Added Insert Voice Marker button and insert_voice_marker() to TextboxDialog
Word Substitution feature (text preprocessing before TTS):
- word_substitution.py: New module (word replacements, ALL CAPS, numerals, punctuation)
- pyqt/conversion.py: apply_word_substitutions() call after clean_text()
- pyqt/gui.py: WordSubstitutionsDialog, word_sub_combo, Settings button,
on_word_sub_changed(), show_word_sub_dialog(), config persistence, queue restore
- pyqt/queued_item.py: 6 new word substitution fields
- pyqt/queue_manager_gui.py: 6 fields added to OVERRIDE_FIELDS and get_current_attributes()
Note: num2words>=0.5.13 was already added to pyproject.toml by upstream.

The app was crashing after importing a .txt and clicking convert because of a missing import. Fixed the imports and removed the legacy abogen.conversion module which doesn't seem necessary anymore.
The 'abogen' command now launches the PyQt6 desktop GUI which requires
display libraries not available in Docker containers. Changed the Docker
CMD to use 'abogen-web' which launches the Flask web UI.
