摘要
为满足数字化语音高精度的识别率及数字化编码高速传输的需求,设计了便携式语音数字化网络传输系统,集成了WM8978声卡芯片及W5500以太网芯片,采用STM32F4系列高速处理器进行语音高保真数字化编码及网络传输的配置。测试结果表明,经逆向合成的数字化音频网络传输数据,与原始语音信号一致,该系统提高了语音数字化及网络传输的速度和精度。
In order to realize high-precision recognition rate of digital voice and high-speed transmission of digital code,a portable voice digital network transmission system is designed,integrating the sound card chip WM8978 and Ethernet chip W5500.STM32F4 series high-speed processor is used as the MCU to conduct high fidelity digital voice coding and transmission via Internet.Test result shows that through inverse synthesis the network transmissing data of digitalized voice keeps consistent with the original speech signal,the proposed system the speed and accuracy of voice digitzation and network transmission.
