WebAbstract: This paper describes the 8 kb/s speech coding algorithm G.729 which has been standardized by ITU-T. The algorithm is based on a conjugate-structure algebraic CELP (CS-ACELP) coding technique and uses 10 ms speech frames. The codec delivers toll-quality speech (equivalent to 32 kb/s ADPCM) for most operating conditions. WebG.729 digitizes analog voice signals producing output at 8 kilobits per second (Kbps) with 8:1 compression and employs an algorithm called conjugate-structure algebraic code-excited linear prediction (CS-ACELP). G.729 has several extensions or annexes. The two most common are G.729A and G.729AB. birthday party photo booth

G.729 is a royalty-free narrow-band vocoder-based audio data compression algorithm using a frame length of 10 milliseconds. It is officially described as Coding of speech at 8 kbit/s using code-excited linear prediction speech coding (CS-ACELP), and was introduced in 1996. The wide-band extension of G.729 is called G.729.1, which equals G.729 Annex J. http://gaoresearch.com/products/speechsoftware/other/g729.php
