The transmission method allows digital compressed speech signals or other data stored on a recording medium, e.g. a semiconductor chip, to be transmitted at a higher rate than real-time via an ISDN telephone or a mobile telephone. Also included are Independent claims for the following: (a) a method for reception of digital compressed speech signals transmitted via a telephone and real-time reproduction of the speech signals; (b) an interface device for transmission of stored compressed speech signals; (c) an interface device for reception and reproduction of a compressed speech recording; (d) a telephone keyboard with compressed speech signal transmission and reception functions |
