Create text transcripts of the words spoken in a sound file. Most plain text editors will be fine for this.
One potential complication is that plain text on windows may be saved "end of line" characters that are not compatible with make_text_grids, the perl utility that parses transcripts and passes them to pyalign.py. You can use the unix utility d2u to change the line endings (this is a separate download into your instance of the BPM).
If there is a portion of the audio file that you don't want to transcribe, and thus won't include in the tagged database, you can add a "skip region" line to the transcript. For example, if there is a 300ms long beep at the beginning of the audio file you can skip the beep by
# 0,0.3 word, word, word # 1,1.7
