ABSTRACT:
The invention relates to a method and a transcription system (T) for transcribing dictations, in which a dictation file (5) is converted into a text file (8), and subsequently the text file (8) is compared with the dictation file (5). To increase the speed for the subsequent correction, provision is made that during transcription of the dictation file (5) a confidence value is generated for a transcribed text passage of the text file (8), and a comparison of the text file (8) with the dictation file (5) takes place only in respect of those text passages for which the confidence value of the text passage is below a confidence limit, i.e. a text passage recognized as possibly defective is present.
