1
Choose a difficult sample
Select a passage with the accents, background noise, overlapping voices, or specialist terms that appear elsewhere in the recording. If those problems are absent, choose an ordinary passage and note that your test may not represent harder sections.
2
Make a draft
Use the route that fits your scenario. For a browser tool, begin with audio you are allowed to submit; for manual work, listen in short segments. Keep the original recording available for comparison rather than treating the draft as evidence on its own.
3
Count the corrections
Review names, numbers, speaker turns, and unclear words against the audio. If fixing the sample takes longer than typing it yourself, switch methods. Record your formatting decisions so the rest of the transcript stays consistent.
