1. A speech recognition system comprising: an input for receiving a speech representative signal; a first memory for storing a representation of the received signal suitable for audible reproduction; a speech recognizer operative to represent the received signal as a sequence of recognized words; a second memory for storing the sequence of recognized words, where each recognized word is stored in association with a marker indicating a correspondence between the word and a segment of the received signal in which the word was recognized; a controller operative to: enable a user to review at least part of the sequence of recognized words by causing a synchronous reproduction of an audible and visible representation of the part of the sequence of recognized words, the synchronous reproduction including audibly reproducing a corresponding part of the received signal stored in the first memory and for each segment of the corresponding part of the received signal, at the moment when the segment is being audibly reproduced, indicating on a display a textual representation of a recognized word which corresponds to the segment; the correspondence being given by the markers stored in the second memory; detect whether the user has provided an editing instruction, while the synchronous reproduction is active; and pause the synchronous reproduction in response to having detected an editing instruction during the synchronous reproduction, and cause the editing instruction to be performed.
