Patent ID: 8612218

Claim:
A method for outputting a speech signal ( 11 ), wherein speech signal frames ( 1 , 3 ) are received by a controller and are used in a predetermined sequence to produce the speech signal ( 11 ) to be output, wherein, in the situation in which at least one speech signal frame ( 2 ) to be received is not received, at least one substitute speech signal frame ( 100 ) is used instead of the at least one speech signal frame ( 2 ) which has not been received, wherein the at least one substitute speech signal frame ( 100 ) is produced by the controller as a function of at least one previously received speech signal frame ( 1 ), characterized in that, in the situation in which the at least one previously received speech signal frame ( 1 ) has a speech signal without voice, the at least one received speech signal frame ( 1 ) is filtered by means of a linear prediction filter, the speech signal of the at least one substitute speech signal frame ( 100 ) is produced by the controller by means of a noise signal ( 75 ) generated from a uniformly distributed noise signal ( 76 ) multiplied by a scaling factor ( 77 ) determined as a function of the signal energy in the filtered speech signal ( 52 ); wherein the filtered speech signal ( 52 ) is subdivided into respective partial frames with respective partial speech signals, in that the respective signal energy is determined for each partial speech signal, and in that the scaling factor ( 77 ) is determined as a function of that signal energy which has the lowest value of the respective signal energies.
