- 语音编码方案的选取对移动通信系统的通话质量、信道容量等有重要影响。本文讨论了TD-SCDMA系统中AMR语音编码的自适应机制,同时分析了AMR中代数码本线性预测(ACELP)算法及实现过程。该方案可以在一块TMS320C5510上实现。-The selection of voice coding schemes for mobile communication systems the quality of the call, such as channel capacity have had a
AT89C52ANDISD2560design
- 目前,语音合成、语音识别、语音存储和回放技术的应用越来越广泛,尽管利用一般的单片机测控系统中都有的硬件电路¬ (如A/D、 D/A、存储器等)能完成语音信号的数字化处理,但是功能比较单一、且效果不是很好。本文采用单片机AT89C52与语音芯片ISD2560组成的语音存储系统,实现了语音的分段录取、组合回放,结合LCD液晶显示模块OCMJ2X8,可实现简单的公交报站功能。系统硬件电路简单,调试方便,性价比高,实用性强。 -Currently, speech synthesis, spee
