Efficient Encoding and Decoding of Speech.

reportActive / Technical Report | Accession Number: ADA083080 | Open PDF

Abstract:

This report discusses work on converting the output of the adaptive predictive coder into a fixed-rate bit-stream, and on improving the coded speech quality by means of various noise shaping filters. Also discussed are the computational complexity of the algorithm.
