The G.729 vocoders perform voice compression at bit rates that vary between 6.4 and 12.4 kbps. The figure below shows an example of the G.729 vocoder connected to a digital communication channel. The input speech is fed into the G.729 encoder as a stream of16-bit PCM samples, sampled at a rate of 8000 samples/second.

G.729 is a voice audio data compression algorithm that compresses voice audio in chunks of 10 milliseconds. Music or tones such as Dual-tone Multi-frequency (DTMF) signaling or fax tones cannot be transported reliably with this codec, and thus use G.711 or out-of-band methods to transport these signals.

I have one doubt.As you know In G.729 Codec the compression rate is 1/8. But here in 10 ms, 80 words (160 bytes) are compressed into 80 bits (10 bytes).Then how can we say this is 1/8th compression? 10 milisecond data = one frame; One Frame = 80 samples of speech wave, 1 sample = 16bit data 16bit = 2 bytes
