Abstract
In a speech recognition system, the received speech and the sequence of words, recognized in the speech by a recognizer (100), are stored in a memory (320, 330). Markers are stored as well, indicating a correspondence between the word and a segment of the received signal in which the word was recognized. In a synchronous reproduction mode, a controller (310) ensures that the speech is played-back via speakers (350) and that for each speech segment a word, which has been recognized for the segment, is indicated (e.g. highlighted) on a display (340). The controller (310) can detect whether the user has provided an editing instruction, while the synchronous reproduction is active. If so, the synchronous reproduction is automatically paused and the editing instruction executed.
