the voice signal, since we are interested in not only knowing what was said, but also in being able to identify the speaker. However, no confusion should result, and we do not attempt to make any distinction here. II. Basic Issues in Speech Coding Speech and audio coding can be classified according to the bandwidth occupied by the input and the

G. 711 • Pulse Code Modulation (PCM) codecs are the simplest form of waveform codecs. • Narrowband speech is typically sampled 8000 times per second, and then each speech sample must be quantized. • If linear quantization is used then about 12 bits per sample are needed, giving a bit rate of about 96 kbits/s.

The most common codec specifications, and one that all PacketCable and other VoIP implementations must support, is G.711. This codec specifies sampling the voice signal 8,000 times a second and encoding it to 8 bits, using either the mu-law or A-law (see Section 6.3.2). This is noncompressed voice coding, as used in the PSTN. It yields the highest voice quality but …
