03 / UTILITIES

01 / Context

The problem

Browser text-to-speech is convenient but inconsistent. Cloud narration can become costly and sends editorial content to a third party. The local workflow creates reusable audio files on the author's own machine.

03 / System

Privacy & architecture

A local Python and FFmpeg pipeline triggered through an npm command; generated MP3 files become static site assets.

04 / Honest notes

Known limits

  • Generation speed depends on the computer and article length.
  • Pronunciation and pacing still need a listening pass before publishing.
