Use bin/zip to exercise the same local-file pipeline used by the bot:
THREADS=1 TTS=OmniVoice /home/braulio/.rvm/wrappers/ruby-3.4.4/ruby bin/zip \
1908kybalion-pages-1-10.pdf \
speed=1.0The default audiobook voice is female, middle-aged, moderate pitch, american accent.
Override it with voice= when testing a specific narrator profile:
THREADS=1 TTS=OmniVoice /home/braulio/.rvm/wrappers/ruby-3.4.4/ruby bin/zip \
1908kybalion-pages-1-10.pdf \
speed=1.0 \
voice=male,young_adult,moderate_pitch,american_accentThe voice= value is passed to OmniVoice as the direct voice instruction on each TTS request. Use underscores for spaces inside attributes when calling from the shell, for example young_adult, moderate_pitch, or american_accent.
