摘要： A system and method for determining and authenticating a person's identity by generating a behavioral profile for that person by presenting that person with various stimulus and measuring that person's response characteristics in an enrollment stage. That person's response profile, once generated is stored. When that user subsequently needs to access a secure resource, that user to be authorized is presented with the stimulus that was presented at the time of generating that person's behavioral profile and the person's responses are detected and compared to his/her behavioral profile. If a match is detected, that user is identified. The user's behavioral response may be in the form of signals as detected by sensor means that detects visual or audible emotional cues or as signals resulting from that person's behavior as detected by polygraph or EEG devices.
摘要翻译：一种系统和方法，用于通过向该人呈现各种刺激并且在登记阶段测量该人的响应特征来产生该人的行为概况来确定和认证一个人的身份。一旦生成，该人的响应配置文件被存储。当该用户随后需要访问安全资源时，被授权的用户被呈现出在生成该人的行为概况时呈现的刺激，并且检测到该人的响应并将其与他/她的行为概况进行比较。如果检测到匹配，则识别该用户。用户的行为响应可以是通过传感器装置检测到的信号的形式，该传感器装置检测视觉或听觉的情绪提示，或者是由测谎仪或EEG设备检测到的该人的行为产生的信号。

摘要： Methods and apparatus are provided for sequential authentication of a user that employ one or more error rates characterizing each security challenge. According to one aspect of the invention, a user is challenged with at least one knowledge challenge to obtain an intermediate authentication result; and the user challenges continue until a cumulative authentication result satisfies one or more criteria. The intermediate authentication result is based, for example, on one or more of false accept and false reject error probabilities for each knowledge challenge. A false accept error probability describes a probability of a different user answering the knowledge challenge correctly. A false reject error probability describes a probability of a genuine user not answering the knowledge challenge correctly. The false accept and false reject error probabilities can be adapted based on field data or known information about a given challenge.

摘要： In large-scale deployments of speaker recognition systems the potential for legacy problems increases as the evolving technology may require configuration changes in the system thus invalidating already existing user voice accounts. Unless the entire database of original speech waveform were stored, users need to reenroll to keep their accounts functional, which, however, may be expensive and commercially not acceptable. Model migration is defined as a conversion of obsolete models to new-configuration models without additional data and waveform requirements. The present disclosure investigates ways to achieve such a migration with minimum loss of system accuracy.
摘要翻译：在扬声器识别系统的大规模部署中，传统问题的潜力随着不断变化的技术可能需要系统中的配置更改而增加，从而使已经存在的用户语音帐户无效。除非存储了原始语音波形的整个数据库，否则用户需要重新注册以保持其帐户的功能，然而，这可能是昂贵的并且在商业上是不可接受的。模型迁移定义为过时模型转换为新配置模型，而不需要额外的数据和波形要求。本公开调查了以最小的系统精度损失实现这种迁移的方式。

摘要： A method and system for speaker recognition and identification includes transforming features of a speaker utterance in a first condition state to match a second condition state and provide a transformed utterance. A discriminative criterion is used to generate a transform that maps an utterance to obtain a computed result. The discriminative criterion is maximized over a plurality of speakers to obtain a best transform for recognizing speech and/or identifying a speaker under the second condition state. Speech recognition and speaker identity may be determined by employing the best transform for decoding speech to reduce channel mismatch.
