This is the video (53 minutes) of the keynote speech I gave on 4 July at the IAFL conference in Melbourne.
It is intended for a forensic linguistics audience, and, as mentioned in the first minute, it goes rapidly through some established background about forensic transcription and translation, in order to bring together some key points for discussion about what is needed in order to ensure reliable transcription and translation of forensic audio used as evidence in court. If you are not in the target audience, you are of course welcome to new this video, but you might find one of the other videos or readings available on this site gives you a better introduction.
