System for generating a wideband signal from a narrowband signal using transmitted speaker-dependent data
First Claim
1. An electronic communication method comprising:
- transmitting a narrowband speech signal comprising a narrowband version of speech utterances of a speaker;
transmitting speaker-dependent data comprising data correlating narrowband versions of the speech utterances of the speaker with corresponding wideband versions of the speech utterances of the speaker;
receiving the narrowband speech signal and the speaker-dependent data; and
using 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.

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.

18. A system for use in communicating speech signals to a receiving party, the system comprising:
-
a transducer for converting speech utterances of a speaker into a wideband electronic waveform;
a speaker-dependent data generator adapted to generate speaker-dependent data correlating narrowband versions of speech utterances of the speaker with corresponding wideband versions of the speech utterances of the speaker, where the wideband versions of the speech utterances of the speaker correspond to the wideband electronic waveform provided through operation of the transducer;
a transmitter adapted to transmit the speaker-dependent data as well as a narrowband signal corresponding to a narrowband version of the speech utterances of the speaker, where the narrowband version of the speech utterances of the speaker comprise the speech utterances that are to be communicated to a receiving party. - View Dependent Claims (19, 20, 21, 22, 23)
