A method for generating subtitles for audiovisual material received and analyses a text file containing dialogue spoken in audiovisual material and provides a signal representative of the text. The text information and audio signal are aligned in time using time alignment speech recognition and the text and timing information are then output to a subtitle file. Colors can be assigned to different speakers or groups of speakers. Subtitles are derived by receiving and analyzing a text file containing dialogue spoken by considering each word in turn and the next information signal, assigning a score to each subtitle in a plurality of different possible subtitle formatting options which lead to that word. The steps are then repeated until all the words in the text information signal have been used and the subtitle formatting option which gives the best overall score is then derived.
