Description: This paper deals with the problem of speech enhancement when a
corrupted speech signal with an additive colored noise is the only
information available for processing. Kalman filtering is known as
an effective speech enhancement technique, in which speech signal
is usually modeled as autoregressive (AR) process and represented
in the state-space domain.-This paper deals with the problem of speech enhancement when a corrupted speech signal wit h an additive colored noise is the only informat ion available for processing.

Description: 文章提出了基于多带语减法改进的增强系统,并在TI会司的浮点处理器TMS320C6713上实现。改进的多带语减法将信号频语非线性的分成4个互不重叠的频带, 每个频带分别做不同系数的语减运算, 因此能很好的滤除有色噪声。工程实现证明此设计能有效的抑制色噪声和音乐噪声, 即便在低信嗓比环境也能有较好增强效果.-In this paper, a language based on multi-band subtraction improved augmentation system, and TI will Division TMS320C6713 floating-point processor to achieve. Improved multi-band frequency signal subtraction language phrase is divided into four non-linear non-overlapping frequency bands, each band separately by different coefficient computing language, so they can filter out a good colored noise. Proves that the design works to achieve effective inhibition of color noise and music noise, even in low sNR environment can also enhance the effect of better.
