Abstract: A storage module which can be inserted into a data processing apparatus, such as a dictating apparatus, includes an at least partly random accessible storage device (5) for the storage of digital data signals and an access device for serially accessing storage locations in the storage device. The storage device requires refreshing and cooperates with a refresh device (6) for refreshing data signals stored in the storage device (5). The refresh device (6) includes additional storage devices (11) which store, upon writing in the storage locations of the storage device (5), start addresses and stop addresses from the access device (9), under the control of a control circuit (12). Only storage locations which are situated between a pair of start and stop addresses are timely refreshed via a refresh control device (20). Such a storage module is preferably used in conjunction with the dictating apparatus for the storage of speech signals.

Abstract: A text-processing system in which the sound signal corresponding to a text is applied not only to a speech-recognition device (1) but also to a first further memory (15) for storage, start marks and end marks being allocated to the words detected by the speech-recognition device (1). These marks are related in time to the sound signals stored in the first further memory (15) and are stored in a second further memory (16). In this way a correlation is obtained between the sound signals stored in the first further memory and the individual words detected by the speech-recognition device. The detected words can be reproduced on a display device (13) thereby enabling the sound signal stored in the first further memory and corresponding to a specific detected word to be reproduced acoustically so as to verify the accuracy of a word detected by the speech-recognition device and to correct an erroneously detected word.
