【Abstract】 Digital Voice Systems Inc.’s AMBE-1000 Vocoder Chip is an high-performance and variable data rates single chip which can be viewed as two separate components, the encoder and the decoder. It provides superior voice quality at low data rates and needs very low power. Patented AMBE voice compression technology has been used in the voice compression software algorithm. TI Inc.’s TLC32044 chip is a 14-bit dynamic range and high precision programmable A/D-D/A chip. This article mainly introduces the performance and the principle of AMBE-1000 and TLC32044, and gives some examples of the application of general speech transaction system .更多还原
