| 摘 要： | 连续斜率可变增量调制(CVSD)语音编码简单且具有良好的抗信道误码能力,擅长处理丢失和被损坏的语音采样,较其他编码方法语音效果更清晰,可靠性更高,降低带宽的同时保证了语音质量.利用DSP芯片研制开发基于语音压缩编码技术的语音产品已经成为一大研究热点.选用TMS320VC5509芯片作为硬件平台,用C语言实现了CVSD语音编解码,能较好实时实现语音编解码.

| Abstract: | The Continual Variable Slope Delta Modulation(CVSD) speech coding is simple and has the ability of the letter a mistake of good anti-code,especially adept at dealing with the lost and destroyed speech sampling data,compared with other methods,it's voice effect is more clearly and lower bandwidth.It has become a most important research field for the development of audio products based on audio compression coding technology by using DSP chips.In the proposed system,the hardware platform based on TMS320VC5509 ... |
