Issue Date: | 1995 | Publisher: | 1063-6676 | Journal: | IEEE Transactions on Speech and Audio Processing | Abstract: | This correspondence presents a new two-stage adaptive vector quantizer of LSF parameters in LPC speech coding. The first codebook is adapted by a partition-delete operation, whereas the code-vectors of the second codebook remain unchanged. The objective and subjective evaluations show that the proposed scheme offers transparent quantization with 22 b/frame. | URI: | http://hdl.handle.net/10553/46169 | ISSN: | 1063-6676 | DOI: | 10.1109/89.397097 | Source: | IEEE Transactions on Speech and Audio Processing[ISSN 1063-6676],v. 3, p. 314-317 |
