[Speech/Voice recognition/combine] PDFFILES DL : 0: 基于ARM7TDMI的SoC片内AC97模块和片外CODEC-UCB1400，采用ITU-T的G.721算法设计语音处理系统提出一种基于低端RISC核的语音系统设计方案。该方案结合SoC的片内eSRAM模块进行性能优化；通过在流片后的实际样机上验证，编码速率为19.88 KB/s，解码速率为22.68 KB/s，达到了语音实时性要求。-ARM7TDMI-based SoC chip AC97 module and off-chip CODEC-mated 00. using the ITU-T G.721 algorithm design voice processing system based on a low-end RISC-nuclear voice EC design. The solutions combine SoC chip modules eSRAM performance optimization; Flow-through in the actual prototype tested, coding rate of 19.88 KB/s and decoding rate of 22.68 KB/s achieve real-time voice requirements.
