摘要
语音参数编码在传输过程中受到干扰,合成语音会产生令人特别讨厌的刺耳尖叫声。FS-1016建议采用前向纠错汉明码(15,11)保护重要参数位,达到良好的听觉效果。文中针对纠错编码在FS-1016中的应用进行了详细介绍,用C语言编程实现,并用实例进行了仿真验证。
If speech parameter coding is disturbed in the transport progress, the synthesis speech can produce harshness that makes listeners uncomfortable. It is proposed that using forward error-correction Hamming coding protects significant parameter bits in FS-1016, which can achieve better listening. Error-correction coding using speech coding FS-1016 is introduced in detail and realized with the C language, and an example is designed for simulation finally.
