Dear List:
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 Regards,
