* Ensure the same acoustic environment for all tone samples
* Use identical duration for opening silence across chapters
* Apply consistent closing silence duration

* Transition Smoothness Techniques:
* Fade-out/fade-in between chapters (subtle, 0.2-0.5 seconds)
* Natural vocal cadence to conclude chapters
* Consistent pacing when announcing new chapters
* Breathing space between chapter title and content
