Tips for better audio transcripts
Record close to the speaker, avoid music under speech, and choose the correct language before uploading. If two people talk over each other the transcript will still be produced, but overlapping words are harder to recognise.
Paragraphs, not a wall of text
We split the transcript into paragraphs at natural pauses and keep timestamps for every sentence, so long recordings are easy to read and easy to jump around in.
