| 摘 要： | 近来出现的高质量低价格的录音及回放设备的高保真度使人耳也难以分辨出原始语音和回放语音,这使得录音回放攻击对说话人识别系统的安全造成了很大威胁.为此,文中提出了一种基于信道模式噪声的录音回放攻击检测方法.该方法根据原始语音与回放语音信道的差异,针对不同信道中的录音及回放设备引入不同的信道模式噪声,采用去噪滤波器和统计帧分...

| Abstract: | The high fidelity of recent recording and playback devices with high quality and low price make it difficult to distinguish the playback recording from the authentic speech even by auditory perception,thus causing the playback attack to pose a huge threat to speaker recognition systems.In order to solve this problem,this paper proposes a playback attack detection method based on channel pattern noise.In this method,according to the channel difference between the playback recording and the authentic speech,d... |
