摘要

介绍了一种2400b /s增强多带激励(EMBE)语音编码器的设计与实现。编码器使用由Griffin和Lim最初提出的多波段激励(MBE)模型的变体来产生自然的声音和可理解的语音。使用音调自适应的可变频带结构来表示语音决策,对谐波幅度进行感知加权频谱平滑,并使用四路分裂矢量量化器对语音频谱进行有效的矢量量化,以实现2400 b/s的高质量语音。以DAM和DRT分数的形式给出了安静和办公环境下的客观性能结果,表明该编码器非常适合需要低速率通信质量语音的应用。

An enhanced multiband excitation speech coder at 2,400 b/s
The design and implementation of a 2400 b/s enhanced multiband excitation (EMBE) speech coder is described. The coder uses a variation of the multiband excitation (MBE) model originally proposed by Griffin and Lim to produce natural sounding and intelligible speech. A pitch-adaptive variable band structure is used for representing voicing decisions, with perceptually weighted spectral smoothing of harmonic amplitudes, and efficient vector quantization of speech spectrum using a four-way split vector quantizer to achieve high quality speech at 2,400 b/s. Objective performance results, in the form of DAM and DRT scores, are presented for quiet and office environments, indicating this coder is well suited for applications requiring low rate communications quality speech.
