Abstract

An electronic communication system is set forth that includes the transmission of a narrowband speech signal corresponding to a narrowband version of speech utterances of a speaker as well as the transmission of speaker-dependent data. The speaker-dependent data may be used to correlate narrowband versions of the speech utterances of the speaker with corresponding wideband versions of the speech utterances of the speaker. Both the narrowband speech signal and the speaker-dependent data are received by a receiving party. A receiver at the receiving party uses the narrowband speech signal and the speaker-dependent data to generate a wideband speech signal corresponding to a wideband version of the speech utterances of the speaker.
