TL;DR: In this article, a method and an apparatus for determining an encoding mode for improving the quality of a reconstructed audio signal is presented. But this method is not suitable for the case where there is an error in the determination of the initial encoding mode, generating a modified encoding mode by modifying the initial mode to a third encoding mode.

Abstract: Provided are a method and an apparatus for determining an encoding mode for improving the quality of a reconstructed audio signal. A method of determining an encoding mode includes determining one from among a plurality of encoding modes including a first encoding mode and a second encoding mode as an initial encoding mode in correspondence to characteristics of an audio signal, and if there is an error in the determination of the initial encoding mode, generating a modified encoding mode by modifying the initial encoding mode to a third encoding mode.

Variable rate speech coding

- 21 Dec 1999
TL;DR: In this paper, variable rate coding of a speech signal is proposed to achieve low average bit rates by only employing high fidelity modes (i.e., high bit rate, broadly applicable to different types of speech) during portions of the speech where this fidelity is required for acceptable output.
