Alignment "doubling"

[aolney]

align.sh is doubling output, and the times are way off. Here is the STM, which was generated from the SRT subtitles (CC) from FFMPEG:

Any suggestions would be appreciated. Regular ASR functionality (with kaldi) is working fine. FWIW my steps and utils are linked to kaldi and not to eesen.

The problem seemed to be in the Makefile. Instead of using the STM, it was running LIUM. Below is my align.sh that seems to have fixed this problem:

#!/bin/bash

# Copyright 2016  er1k
# Apache 2.0

# Prepare data for, and run align_ctc_utts.sh script that generates word-level alignments
# in an "Eesen Transccriber-centric" way  output is found in build/output/<basename>.ali

# Required inputs:
#
# * a 'hypothesis' text file for which to compute alignments, extension .txt
#   one utterance per line. If no hypothesis text is found, text
#   is obtained from the STM file below
# * an STM file with utterance/segment timings - 'perfect' transcription
# * an audio file, extension can vary (.mp3, .wav, .mp4 etc)

will need to look into this some other time, please let me know if you have other information or updates

Only that once the STM was properly used, the doubling issue went away. However, the alignments still seemed off.
