High Quality 2400 Bps Vocoder Research

Global trends toward complex, high-capacity telecommunications emphasize a growing need for high quality speech coding techniques that require less bandwidth. Telecommunications networks of the future, such as Motorola's IRIDIUM, will demand very high fidelity voice communications at the lowest possible bit rates. Inadequate vocal system models of current 2400 bps vocoder technologies often fail to reproduce the full character and resonance of the original speech, and are thus unacceptable for systems requiring high-quality voice communications. Motorola research in the high-quality 2400 bps arena has resulted in innovative solutions to high quality, low-bandwidth voice communication requirements.
