3 ) we try to import the bayesian adaptation , which is widely used in speech recognition , into speaker verification . we use bayesian maximum a posteriori estimation training a speaker model from background model , to solve the problem of model miss matching in speaker verification system 3 )为了解决说话人确认中存在的模型不匹配问题,尝试将语音识别中的贝叶斯自适应算法引入到基于高斯混合统一背景模型的说话人确认系统。
The technical development of verification system has been introduced firstly in the thesis , the theory for the hardware structure are then provide , finally , the hardware system design will be demonstrated from three aspects : 1 . the design of software & hardware co - emulation verification system at pcb level , including the pci interface board and the csm board . 2 最后从三个方面重点阐述了硬件系统的设计: 1 .软硬件协同验证系统三种验证模式板级系统的设计,包括两块pcb板卡的设计,一块是pci接口板卡的设计,另一块是联合仿真csm板卡的设计。
In the parameter - based fusion methods , we analyze the applicability of the bayes theory and neyman - pearson rule when they are applied to identity verification systems ; we compare global and local parameter in bayes fusion system ; we further propose weighted method , and apply it to bayes - and neyman - pearson - based identity verification system , and get a more higher verification result 在有参数的融合方法中,分析了bayes理论和neyman - pearson准则在融合时的适用范围;针对bayes融合系统参数的选取问题,我们分别进行了全局参数和局部参数的融合实验;并提出了加权思想,将其用于bayes理论和neyman - pearson准则的身份识别融合系统,得到了较好的鉴别效果。
At present , most speaker recognition systems are working on the computer . after primarily focusing on technique of feature extraction and recognition , this paper realizes a set of practical speaker verification system on spce061a , which can be applied to many fields of voice control 目前国内外绝大部分说话人识别系统都是基于计算机来进行的,本文在重点研究说话人识别系统中的特征参数提取、识别方法等关键技术的基础上,在凌阳16位单片机spce061a上实现了一套具有实用意义的说话人确认系统,在进一步完善的情况下,可将其应用于语音门锁、语音考勤、医用语音控制等。
For instance , fingerprint verification system , pupil verification system , speech verification system etc . in comparison with characteristics of above system , the characteristics of face are more directly , friendly and convenient characteristic and can easily be to accepted by the customers verification system face is nonrigid and largely variational , so face recognition is a complicated extensive and challenging research task 例如:指纹身份验证系统、瞳孔身份验证系统、语音验证系统等。相对于以上系统的生物特征,人脸特征又具有直接、友好、方便等特点,并易于被用户所接受。由于人脸是非刚体,变化较大,因此人脸识别是一个复杂、涉及面广而且应用前景广阔的研究课题。
For the healthy development of our securities market and effective implementation of our securities supervision , by referring to foreign experience and our current situation , we shall continuously improve the supervision system with csrc as its core , further strengthen the legal system establishment of securities market , improve laws and regulations system of securities supervision , strengthen self - disciplinary management of securities market , further improve the verification system of securities issuing , enhance securities supervision power , perfect information release system , quote credit trading system and so on 为了使我国的证券市场健康发展、使我国的证券监管能够有效执行,根据国外的经验及我国的现状,我们应采取继续完善以证券监督管理委员会为核心的监管体制,进一步加强证券市场的法制建设,完善证券管理的法规体制;加强证券市场的自律管理;进一步完善证券发行的审核制度;加强证券监管力度,完善信息披露制度;引用信用交易制度等措施。
Systems are verified in a transaction level not an event - based level which the existing verification methods are based on . this method has been successfully implemented through the soc hardware software co - verification system which is developed by me and other partners in our group . in the particular implement process , the whole system is divided into two parts 在具体的实现过程中,将系统划分为两大部分来实现,软件部分采用systemc这一高级的编程语言对软件侧进行建模,对数据结构进行抽象打包,实现数据的传送、接收以及结果的查看等;在硬件部分,主要由veriloghdl语言编写的状态机实现bfm的功能,包括数据结构进行解包并信号级别信息的转换, bfm与dut的数据通信,以及对信号进行打包传送等工作。
( 4 ) because the speaker ’ s status is changing slowly all the time , a new online pattern updating technique is presented . after optimizing the mode of ‘ verifying after training ’ to the mode of ‘ training while verifying after training first ’ , the speaker verification systems have stronger robustness . ( 5 ) programming with assembler language , a set of practical speaker verification system on spce061a is realized ( 4 )针对说话人发音习惯的缓变性,提出了模板在线更新策略,把通常使用的“先训练再识别”的更新模式,优化为在“先训练”条件下的“边训练边识别”的更新模式,从而使得说话人确认系统可适应说话人本体的特征缓变,具有较强的适应性。
Through comparison of securities supervision system , issuing market , trading market , serving market and so on among united kingdom , united states , japan and china , we can find that the following problems in our securities supervision : multi - management and inconsistent policies , incomplete jurisdiction system , irregular self - disciplinary system , incomplete verification system of securities issuing market , high risks brought by single type broker dealers , weak securities supervision , backward supervision concept and poor quality of supervisors 通过将我国与英、美、日等几个主要国家进行证券监管体系、发行市场、交易市场、服务市场等方面的比较,可以看出,我国在证券监管方面存在证券监管多头管理、政出多门,证券监管的法律体系不完善,证券市场的自律机制不健全,证券发行市场的核准制不完善,证券商种类单一、风险较高,证券监管乏力,监管理念落后,监管人员素质较低等方面的问题。
Signature and verification systems , such as ecdsa etc , the discuss about key exchange systems such as deffie - hellman systeme , etc . this thesis also discussed several applications and information safety products of the elliptic curve cryptosystems at the finite field too , such as digital signature , the group signature , the application in the smart card Ecdsa等签名验证体制的选取, deffie - hellman等密钥交换体制的研究。论文也讨论了基于有限域上椭圆曲线公钥密码系统的若干应用和信息安全产品,如数字签名,组签名,在智能卡中的应用。
