麦克风阵列用于语音信号处理应用，例如电话会议和远程呈现，以便在存在来自其他说话者的语音信号、混响和背景噪声的情况下增强期望的语音信号。这些阵列通常提供单通道输出，使得在输出信号中没有空间信息可用。然而，关于声源的空间信息可以增加由人类收听者感知的语音信号的可懂度。这项工作提出了一个数学框架，广义球形阵列波束形成，除了抑制噪声和混响，旨在保留空间信息的来源在记录场地。广义波束形成，制定在球面谐波域，是基于双耳声音再现，其中头部相关的传递函数被纳入耳机演示。所提出的广义波束形成器的性能相比，单通道输出最大方向性波束形成器。与人类受试者的听力测试表明，当使用的广义波束形成器的可懂度提高在低输入信噪比。
Microphone arrays are used in speech signal processing applications such as teleconferencing and telepresence, in order to enhance a desired speech signal in the presence of speech signals from other speakers, reverberation and background noise. These arrays usually provide a single-channel output, so that no spatial information is available in the output signal. However, spatial information on the sound sources may increase the intelligibility of a speech signal perceived by a human listener. This work presents a mathematical framework for generalized spherical array beamforming that in addition to suppressing noise and reverberation, is aiming to preserve spatial information on the sources in the recording venue. The generalized beamforming, formulated in the spherical harmonics domain, is based on binaural sound reproduction where the head-related transfer functions are incorporated into a headphones presentation. The performance of the proposed generalized beamformer is compared to that of a single-channel output maximum-directivity beamformer. Listening tests with human subjects show that when the generalized beamformer is used the intelligibility is improved at low input SNRs.
