| 摘要 |
<p>The present invention relates to a method for generating wideband speech signals from bandlimited speech signals transmitted and received by a first party and by a second party, comprising generating and transmitting first speaker-dependent data by the first party, receiving the first speaker-dependent data by the second party and generating first wideband speech signals on the basis of the first speaker-dependent data by the second party. The invention also relates to a system for bandwidth extension of bandlimited speech signals transmitted and received by a first party and by a second party, comprising a first database generated by the first party comprising first speaker-dependent data, a first transmitting means for transmitting the first database to the second party, a first analyzing means configured to analyze the bandlimited speech signals received by the second party to determine at least one first analyzed bandlimited speech parameter, a first mapping means configured to determine at least one first wideband speech parameter from the at least one first analyzed bandlimited speech parameter on the basis of the first database and a first wideband synthesizing means for synthesizing first wideband speech signals on the basis of the at least one first wideband speech parameter.</p> |
