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.
Claims20
An encoding apparatus including a processor having computing device-executable instructions, the apparatus comprising:
- a mode selection unit, controlled by the processor, to select an encoding mode of a frame that is included in an input speech signal;
- and
- an unvoiced mode encoder to encode a frame having an unvoiced mode for an unvoiced speech as the selected encoding mode.
A decoding apparatus including a processor having computing device-executable instructions, the apparatus comprising:
- an encoding mode verification unit, controlled by the processor, to verify an encoding mode of a frame in an input bitstream;
- and
- an unvoiced mode decoder to decode a frame having an unvoiced mode for an unvoiced speech as the selected encoding mode.
An encoding method comprising:
- selecting an encoding mode of a frame that is included in an input speech signal;
- and
- encoding, using a processor, a frame having an unvoiced mode for an unvoiced speech as the selected encoding mode.
