ESV Text/Audio Aligner

Pulls down the ESV text and audio from the ESV API, then aligns the text and audio chapter-by-chapter by means of CMU Sphinx and generates {book}.{chapter}.timings.json timing files in the data/ directory (see output for John 3). The audio and text for each chapter is also saved in this directory. Previously-aligned chapters are skipped unless --forced. There is an ongoing discussion on the CMU Sphinx forums on the quality of the alignment data it provides.

ESV API usage terms (see full conditions):

Background

This project was birthed out of a desire to realize the read-along app, where the currently-spoken word in the audio is higlighted in the text on the screen. I made an HTML5 Audio Read-Along prototype (includes writeup) featuring a passage from Luke 2 of the ESV, but the actual audio timing data for the Luke 2 sample I had to obtain manually (read: painstakingly). This project aims to generate the audio word timings automatically so that the entire Bible can be used in a read-along app.

Usage

$ python align.py [-f|--force] [osisBook [[chapter], [chapter]...]]...

Examples

Align Genesis 1:

$ python align.py Gen 1

Align John 3, overridding any existing timings:

$ python align.py -f John 3

Align Genesis 1-3, Psalm 1, and all of Colossians:

$ python align.py Gen 1 2 3 Ps 1 Col
