Abstract:
An apparatus and a method to encode and decode a speech signal using an encoding mode are provided. An encoding apparatus may select an encoding mode of a frame included in an input speech signal, and encode a frame having an unvoiced mode for an unvoiced speech as the selected encoding mode.

Claim (Index 2):
An encoding apparatus comprising:\n at least one processor configured to: if a bitrate is higher than a predetermined bitrate, encode a frame based on a transform coded excitation (TCX) technology; if a bitrate is lower than the predetermined bitrate, select, an encoding mode of the frame among a plurality of modes including a first encoding mode and a second encoding mode, based on a plurality of parameters including the bitrate and a result of signal classification; if the encoding mode is the first encoding mode, encode the frame by performing a linear prediction based encoding; and if the encoding mode is the second encoding mode, encode the frame by using the transform coded excitation (TCX) technology.
