Abstract
The invention relates to a method of supporting the proof-reading of a text (2, 30) obtained in particular by speech recognition from a speech signal (1), of which at least one text component (B1 to B5) has a reliability level (3) for its correctness, which method comprises a control of the progression of the replay speed (12, 13) of the part of the speech signal (1) belonging to the text component (B1 to B5) as a function of the reliability level (3) of the text component (B1 to B5).Faster replay of the reliable passages of a speech signal (1) shortens the working time required for proof-reading, while the slow replay of the unreliable passages raises the attention of the proof-reading user. An acoustic and/or visual (32) marking of the passage as a function of its reliability (3) is advantageous. The method according to the invention is particularly suitable for implementation within a speech recognition system.
