Abstract: With the increase of human-computer voice interaction scenes in recent years, using microphone array speech enhancement to improve speech quality has become one of the research hotspots. Different from the ambient noise, the interfering speaker′s speech and the target speaker are the same speech signal in the multiple speaker separation scene, showing similar time-frequency characteristics, which poses a higher challenge to the traditional microphone array speech enhancement technology. For the multiple speaker separation scenario, the spatial response cost function of microphone array is constructed and optimized based on deep learning network. The desired spatial transmission characteristics of microphone array are designed through deep learning model training, so as to improve the separation effect by improving the beamforming performance. Simulation and experimental results show that this method effectively improves the performance of multiple speaker separation.

隨著人與機器之間的語言交互逐漸頻繁,,更需要考慮噪聲、混響和其他說話人的干擾等引起語音信號質量下降的因素對語音識別造成的影響,,語音增強技術[1]可以有效地從受干擾的信號中提取純凈的語音,,而麥克風陣列比起單個麥克風可以獲取更多的語音信息和時空特征,因而麥克風陣列語音增強技術被廣泛應用在智能家居,、車載系統(tǒng)和音(視)頻會議等領域,。
麥克風陣列對信號進行空間濾波,可以增強期望方向上的信號并抑制方向性噪聲,,實現(xiàn)語音增強,。傳統(tǒng)麥陣語音增強算法;如形成固定波束的濾波累加波束形成算法(Filter-and-Sum Beamforming,,F(xiàn)SB)[2],,通過一定長度的濾波器系數(shù)對多通道信號進行濾波累加,實現(xiàn)了頻率無關的空間響應特性,,具有低復雜度,、硬件容易實現(xiàn)等優(yōu)點,但是對于具有方向性的噪聲效果不佳,。
