convert epub file to txt files separated according to TOC, then to audio file using edge-tts or apple-tts in macOS called 'say'
# use edge_tts with default voice
./epub2audiobook.py /path/to/epub /path/to/output/
# specify voice name
./epub2audiobook.py --voice_name zh-CN-YunyeNeural /path/to/epub /path/to/output/
# specify tts method
./epub2audiobook.py --voice_name 'TingTing' --tts_method mac_say /path/to/epub /path/to/output/
# run without outputs
./epub2audiobook.py --dry_run /path/to/epub /path/to/output/When using the tts method of mac_say and the --voice_name option is set to 'auto', which is the default value, the currently activated voice on the system will be used. This is very useful because the say -v command cannot select some voices such as Siri
