传统双话筒降噪应用中，要求采用定向话筒对抗话音串扰问题，并且语音损伤较大，采用抗交叉串绕算法后，仅噪声被抵消，语音信号被保留。分为两个阶段，第一阶段，学习环境，第二阶段，抵消噪声。-Traditional dual-microphone noise reduction applications, the adoption of directional microphone voice against crosstalk, and a larger voice injury, using anti-cross-string around the algorithm, the only noise being offset, voice signals are retained. Divided into two phases, the first stage, the learning environment, the second phase, the offset noise.
