A disk array flushing method and a disk array flushing apparatus. The method includes acquiring a sequence, which is according to physical addresses of logical units, of the logical units in a same redundant array of independent disks (RAID) group in a disk array, and sequentially flushing, according to the sequence of the logical units, concurrent flushing input-outputs (IOs) of the RAID group to the logical units in the RAID group. According to the disk array flushing method and the disk array flushing apparatus, by uniformly scheduling logical units in a single RAID group and performing flushing according to a sequence of physical addresses, it takes less time for a magnetic arm to jump back and forth for addressing, and influences between RAID groups are prevented by means of independent control over the RAID groups, thereby improving flushing efficiency of a disk array, and increasing throughput of the disk array.

A method and device for speaker recognition are provided. In the present invention, identifiability re-estimation is performed on a first vector (namely, a weight vector) in a score function by adopting a support vector machine (SVM), so that a recognition result of a characteristic parameter of a test voice is more accurate, thereby improving identifiability of speaker recognition.
