一种超长时的固话录音系统设计
Design of telephone recording system with ultra-long recording time
摘要
Abstract
In the paper,a real⁃time telephone recording system based on USB flash disk storage was designed. It adopted MELP compressed algorithm and real⁃time voice storage technology. It is able to record speech information for an ultra⁃long time. For example,a 64 GB USB flash drive can store call recording data for several years. The system with small size and low power consumption can be installed in any place,and can be widely used in the field of telephone surveillance.关键词
