Dear List:
This e-mail may not be relevant for this group, but anyway.... I was
reading the book, “Speech Coding and Synthesis” by Kleijn &
Paliwal. In
page 445, from the table we see that for scalar quantization of the
reflection coefficients, it costs 4 bits per parameter for 1 dB
distortion. Similarly,
in page 447, from the table we see that for LAR scalar quantization, it
costs 3.2 bits per parameter for 1 dB distortion. The
above numbers are for narrowband speech coding. Could anyone please let me know
what happens to the above numbers (4 bits and 3.2 bits) for wideband LP based
speech coding? It would be great if you could please suggest some references
as well. In case, there are no
relevant wideband speech coding paper that addresses the numbers for the
reflection coefficient and LAR representation, you may also let me know the
numbers for the LSF representation for the narrowband and wideband scenarios.
Thanks
a lot in advance. Best
