No. We do not charge extra for transcribing strong accents. We have transcribers with many years experience and expertise in transcribing strong regional accents and second or third language English speakers. Neither do we charge extra for background noise or poor quality recordings. We have specialist software to help us detect and extract the speech from a recording. Sometimes recordings are completely inaudible. If this is the case, we will let you know before commencing work and talk through the options.
