A word about transcibing illegible material:
Generally transcriptionists do not do detailed work with inaudible material
, sometimes passing by whole words and phrases that may in fact be deciphered if taken the time and care to do so. We pride our selves in our ability of composing precise transcriptions from illegible audio. Using softwares and hardwares to tweak and repeat certain areas of audio may in fact result in a better understanding of what needs to be translated. When possible we work closely with the people involved, with each case, to have a better understanding of what transpires in the audio in question.
