This repo contains a script for generating an audiobook for Milestones: The Story of WordPress.

The script will automatically download the latest EPUB file from the WordPress book repo, and convert it to audio files using the text-to-speech (TTS) engine on OSX.

The duration of the generated TTS audio will be about 4 hours, depending on the speech rate you choose. Each chapter gets a separate audio file.

./generate-audiobook.php

You may pass the --voice and --rate options accepted by the OS X say command, for example:

./generate-audiobook.php --voice Alex --rate 275

The script depends on the say command in OS X. Audio files will be written to an output subdirectory.

To convert the AIFF audio files from the say command into MP3 files, sox is required (and must be installed with MP3 support). Without sox, only the AIFF files will be created.

To install sox using brew:

brew install sox --with-lame

If you already have sox installed but need to add MP3 support:

brew reinstall sox --with-lame

Files must be converted to MP3 before being used in podcasts.

Generated audio may be used according to Apple's terms of use (likely personal use only).

The output of this script can be used to create a podcast. Upload the contents of the output directory upon completion, and then add the URL to the contained podcast.php file into your podcasting app. Again, this depends on MP3 conversion via sox.
