摘要:
介绍多带激励(MBE)模型原理、分析和合成, 该算法突破了二元激励的局限性, 较好的解决了简单二元激励模型导致的合成语音自然度不够以及抗噪声能力差的问题, 是目前低速率语音编码较理想的方案. 此外, 详细阐述了MBE 编码器的仿真实现方法, 并给出了程序流程和仿真结果. 实验结果表明, 此仿真系统合成的语音在频谱和波形上都和原始语音比较接近, 并具有良好的清晰度和可懂度, 任何熟悉的人都可以辨别说话人.
Abstract:
The paper presents the pr inciple ofMBE (M ultiband Exc itationM ode l) and its analytical and synthetica l m ethods. MBE applies a new exc itation spectrum, thus prov iding h igh qua lity speech reproduction for both clean and no isy speech. The a lgo rithm is an idea l schem e o f current low - speed speech encod ing. The paper a lso illustrates the simu lation o fM BE Encoder and prov ides the flow chat o f the program and the resu lt of the s imu lation. The resu lt show s the synthetica l speech and the o rig ina l speech are sim ilar on the tim e reg ion and the frequency reg ion, and the synthetical speech is o f h igh de finition and com prehension, so the speaker can be easily d istinguished.
