摘要： The intelligibility of speech signals is improved in the many situations where a voice signal is communicated or stored. Means and methods are disclosed for developing a scheme with high voice signal intelligibility without sacrifice of voice quality. The disclosed method comprises certain steps, including, but not limited to: Learning the noise on near-end side and enhancing the far-end voice as a function of the noise level on the near-end side. The disclosed method and apparatus are especially useful to increase the intelligibility of the cell phone's loudspeaker output. The invention includes the processing of an input speech signal to generate an enhanced intelligent signal. In frequency domain, the FFT spectrum of the speech received from the far-end is modified in accordance with the LPC spectrum of the local background noise to generate an enhanced intelligent signal. In time domain, the speech is modified in accordance with the LPC coefficients of the noise to generate an enhanced intelligent signal.

摘要： A noisy signal is picked up by a microphone, digitized by an Analog to Digital Converter and fed to a processor for analysis and wind noise reduction. Most of noise reduction methods are based on the assumption that the interfering noise is stationary or slowly varying compared with speech. This assumption allows “learning” the characteristics of the noise between speech pauses and, based on a noise estimate, to build different filters that reduce the noise. In the case of wind noise this basic assumption is not valid. Wind noise is highly non-stationary, its power and spectral characteristics vary greatly. Because wind noise is not stationary, regular noise reduction methods cannot be used to reduce wind noise. For reducing wind noise effects in a device, the presence of wind should be detected reliably and then a novel approach presented here must be applied to eliminate the wind noise.
摘要翻译：噪声信号由麦克风拾取，由模数转换器数字化，并馈送到处理器进行分析和减少风噪声。大多数降噪方法是基于干扰噪声与语音相比是静止的或缓慢变化的假设。该假设允许“学习”语音暂停之间的噪声的特性，并且基于噪声估计来建立减少噪声的不同滤波器。在风噪声的情况下，这个基本假设是无效的。风噪声非常不稳定，其功率和光谱特性差异很大。由于风噪声不稳定，因此不能采用常规的降噪方法来减少风噪声。为了减少设备中的风噪声影响，应该可靠地检测风的存在，然后必须采用这里提出的新颖方法来消除风噪声。
