Artificial Bandwidth Extension of Wideband Speech by Pitch-Scaling of Higher Frequencies. |
Abstract | ||
|---|---|---|
In this paper, a simple DFT-domain pitch-scaling technique is used to ex- tend the audio bandwidth of wideband speech (50Hz - 7kHz) to the super-wideband range (50Hz - 12kHz). Therefore, the higher frequencies of the wideband signal (6 - 7kHz) are pitch-scaled with a scaling factor of four and the resulting, scaled sig- nal is inserted into the 8 - 12kHz band. A subjective listening test has been conducted wherein itcould be shownthat the new proposalclearly outperforms aprevious method for artificial bandwidth extension which is based on statistical estimation techniques. |
