介绍了一种基于词网的最大似然线性回归无监督自适应算法，并进行了改进。根据解码得到的词网估计变换参数，词网的潜在误识率远小于识别结果，因此可以使参数估计更为准确。传统的一个很大缺点是计算量极大，较难实用，对此本文提出了两个改进技术：1利用后验概率压缩词网；2利用单词的时间信息限制状态统计量的计算范围。实验测定,误识率比传统相对下降了。
Introduced the term network based maximum likelihood linear regression unsupervised adaptive algorithm, and an improved. According to decode the received word net estimated transformation parameters, the word error rate of net potential is far less than the recognition results, it can make parameter estimation more accurate. A major drawback is that the traditional calculation enormously difficult practical, this paper presents two improved technology: 1 compression using word posterior probability network 2 time information using the word limit state statistic calculation. Experimental determination of the relative error rate than traditional down. (2010-08-13, PDF, 220KB, 下载5次)
本系统是利用公共通信网作传输媒体的面向
普通居民的电话录音和自动报警系统。当检测到
电话线路发来的振铃（铃流），经一段时间无人接
听便进行模拟摘机，摘机后将主人留言发送给对
方，最后录入对方语音，直到检测到对方挂机为止
完成录音电话的功能。当有预先设定的警情发生
时，能自动拨打已存储好的三组电话号码或手机、

The paper introduces the hardware of a new kind of alarming system that can dispose image and dial the telephone number by itself. Firstly, the alarming signal is introduced by human sensor which include infrared warning device and microwave sensor. Then the system receives the signal to start the telephone dialing and alarming at the help of dual-tone multifrequency module and speech sounds module. Lastly the image monitor part collects and stores the scene of alarming. It is very good for the practical value and suitable to be spreaded widely. (2010-05-20, PDF, 2266KB, 下载14次)

This system is the use of public communications network to the transmission media for the ordinary residents of the telephone recording and automatic alarm system. When the test sent to a phone line ringing (ringing), then no answer after a period of time to simulate the hook, pick up the owner of a message will be sent to the other side, the last entry the other voice, hang up until the completion of testing to each other recording phone functions. When pre-alarm occurs, can automatically dial stored phone numbers or good three mobile phones, pager numbers, the other hook to automatically play the recorded voice alarm message.
