ITU-T Recommendation G.729 describes a voice compression algorithm based on Conjugate-Structure Algebraic-Code-Excited Linear Prediction (CS-ACELP). Annex A describes a reduced complexity version which is bit-stream interoperable with the full version of G.729. Annex B describes a silence compression scheme that includes Voice Activity Detection (VAD), Discontinuous Transmission (DTX) and Comfort Noise Generator (CNG) algorithms. G.729 is widely used as one of the key software components for packet based voice devices such as VoIP phones and private branch exchanges.
