I transcribe spoken audio (spoken in English) files, from podcast episodes to academic lectures, ensuring correct spelling and tidy document formatting. I transcribe high quality, clear audio at a speed of 2.5 audio minutes per audio minute - often faster if I have a very strong sense of the speaker's speech patterns or the subject matter. Less clear audio or subject matter requiring lots of googling to check for correct spelling may slow the transcription speed to 3-4 times the audio minutes.
