I mean players that include features related to listening to recorded talking for the purpose of putting that into text.
One elementary feature would be a somewhat refined way of play/stopping, jumping back and forward with short-keys.
More advanced features would be to alter various aspects of the sound in order to understand more complex or badly recorded sounds of voices.
(I wouldn't mind an answer indicating a sound-to-text program that would automate all that transcription work as well :))
