Modified Cepstral Feature for Speech Anti-spoofing

The hidden danger of the automatic speaker verification(ASV) system is various spoofed speeches. These threats can be classified into two categories, namely logical access(LA) and physical access(PA). To improve identification capability of spoofed speech detection, this paper considers the research on features. Firstly, following the idea of modifying the constant-Q-based features, this work considered adding variance or mean to the constant-Q-based cepstral domain to obtain good performance. S...     

基于K-means算法的电动汽车充电站在线能量管理

针对电动汽车的充电需求以及未知的实时电价,探讨完整的充电方案,提出一种电动汽车充电站能量管理在线算法,建立由风能、太阳能及电网供电的充电站充电成本优化问题.在电价、风能和太阳能发电量等系统信息已知的条件下,采用离线算法即遗传算法搜索成本最小化问题的全局最优解.由于遗传算法需要已知所有时隙的系统信息,但这些信息是随机分布...
