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. G.729 is a standard for Internet Protocol (IP) Private Branch Exchange …

G.729 codec is an audio data compression algorithm for voice that compresses digital voice in packets of 10 milliseconds duration. Standard G.711 calls take 64kbit/s per call. The G.729 codec compresses the payload to 8kbit/s, giving you up to eight (8) …

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;

G.729 uses 8000 samples per second while using 16 bit linear PCM as coding method. Data compression delay is 10ms for G.729, also G.729 is optimized to use with actual voice signals which leads to DTMF (Dual Tone Multi-Frequency) tones, and high quality music and fax are not supported reliably using the codec.
