This is not a copy+paste proposal:
Hello. I read the project description and I listened to the audio file (you have a transcription sample at the end of this message).
I have an advanced level of English (C1) and Spanish is may native tongue. Also, I have previous experience in transcription, as well as a translator and interpreter.
I have heard the original recording, it has a very poor quality, too much noise, distorsion and the male voice is very low. So maybe I can hear around 25% of the conversation (I get the idea of what they are talking about, though).
Just as a sample, I have made a part of the transcription of the beggining (I can tell that they are both Colombian):
MT: If they don't want to [do it]? I have the medical letter... I have the deeds... And if they start to say "No, not that way"...
I can deliver the rest of the transcription tomorrow.
