Bugs / Correctness Issues

1. IAM ARN double colon (false alarm)

deploy-static-site.yml:31

role-to-assume: arn:aws:iam::504242000181:role/GithubDeployCI

Standard ARN format for IAM is arn:aws:iam:::role/... with no region (empty field), so the double colon is correct. Disregard.

Audiobook generator - text2mp3_piper.py

text2mp3 (Piper TTS)

A cross-platform, fully offline text-to-MP3 pipeline built on Piper TTS.
Designed for long-form reading (ebooks, essays, Project Gutenberg texts) with natural pacing, clean chunk boundaries, and intentional pauses that sound like real speech rather than stitched audio.

This tool:

  • Reads .txt or .pdf (optional page ranges)
  • Cleans and normalizes text for speech
  • Chunks intelligently (paragraph-aware, sentence-safe)
  • Inserts natural pauses between chunks and paragraphs
