摘要： A method is presented which reduces data flow and thereby increases processing capacity while preserving a high level of accuracy in a distributed speech processing environment for speaker detection. The method and system of the present invention includes filtering out data based on a target speaker specific subset of labels using data filters. The method preserves accuracy and passes only a fraction of the data by optimizing target specific performance measures. Therefore, a high level of speaker recognition accuracy is maintained while utilizing existing processing capabilities.

摘要： Automated decision making techniques are provided. For example, a technique for generating a decision associated with an individual or an entity includes the following steps. First, two or more data streams associated with the individual or the entity are captured. Then, at least one time-varying measure is computed in accordance with the two or more data streams. Lastly, a decision is computed based on the at least one time-varying measure. One form of the time-varying measure may include a measure of the coverage of a model associated with previously-obtained training data by at least a portion of the captured data. Another form of the time-varying measure may include a measure of the stability of at least a portion of the captured data. While either measure may be employed alone to compute a decision, preferably both the coverage and stability measures are employed. The technique may be used to authenticate a speaker.

摘要： Methods and arrangements for facilitating speaker identification. At least one N-best list is generated based on input speech, a system output is posited based on the input speech, and a determination is made, via at least one property of the N-best list, as to whether the posited system output is inconclusive.

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： Techniques are provided for generating data based on at least one of physical and behavioral characteristics associated with an individual, an entity or a context, which may then be used for a variety of security and/or meta-data analysis purposes. This may be accomplished, for example, by capturing and processing multiple streams of data, such as conversational meta-data, associated with an individual or an entity, and building statistical models and/or extracting heuristics from such data. The statistical models and/or heuristics may then be used, by way of example, for such purposes as user identification, verification of an identity claim, context detection and further heuristic extraction.

摘要： A system and method for providing continuous confidence-based authentication. The present invention may be implemented in an incremental access authentication system for controlling access to secured data having various levels of security. During the course of a conversational session between user and machine, a confidence-based authentication system according to the present invention will periodically analyze the input speech of a user interacting with the system to compute a “confidence measure” for the validity of an original identity claim i provided by the user at the commencement of the dialog session. The “confidence measure” computation process according to the present invention is seamlessly integrated into the incremental access authentication system so that the system can tailor its interaction with the user based on its confidence in the original identity claim.
