Abstract

A speech model, referred to as the multiband excitation (MBE) speech model, has been shown to be capable of synthesizing speech without the artifacts common to model-based speech systems and has been used to develop a 4.8 kb/s speech coder. This system was developed using several new approaches to quantize the MBE model parameters. These techniques were designed to utilize additional redundancy amongst these parameters, thereby permitting more efficient quantization. The result of information listening tests indicate that this system can achieve high quality for both clean and noisy speech as the MBE speech is extremely robust to the presence of background noise in speech
