Troubleshooting

The lecture hall audio is unclear

Distant microphones and room echo reduce accuracy. Use a closer recording source if available.

Technical terms are wrong

Treat the transcript as a draft and correct vocabulary from slides, readings, or course notes.

The file is a full semester archive

Split recordings by lecture or topic so each transcript is easier to process and review.
