A 4?kbit/s Hybrid Speech Coding System
Min Cheng · 2002
It is introduced in this paper a hybrid speech coding technique, which combines a frequencydomain parametric coder (for stationary voiced and stationary unvoiced speech) with a timedomain waveform coder (for transition speech). Subjective listening tests demonstrate that the 4 kbit/s hybrid coding scheme competes favorably with CELP coders at low bitrates.
