The invention relates to a method for the artificial extension of the bandwidth of speech signals with the following steps: a) Provision of a wideband input speech signal (s~b(k)); b) Determination of the signal components (S eb(k)) of the wide-band input speech signal (s~b(k)) required for the bandwidth extension from an extension band from the wideband input speech signal (s~b(k)); c) Determination of the temporal envelopes of the signal compo- nents (s eb(k)) determined for the bandwidth extension; d) Determination of the spectral envelopes of the signal compo- nents (S eb(k)) determined for bandwidth extension; e) Encoding of the information for the temporal envelopes and the spectral envelopes, and provision of the encoded information by carrying out the extension of the bandwidth; f) Decoding of the encoded information and generation of the temporal envelopes and the spectral envelopes from the encoded information for the production of a bandwidth-extended output speech signal (s~b(k)). The invention also relates to a device for the artificial ex-tension of the bandwidth of speech signals.
