In this paper, we propose a style translation filter that changes the attribute (style) of the motion coming from the actors' ages, genders, and so on. Using this filter, we can diversify the motions. Specifically, this filter is modeled by the Gaussian process regression that estimates the difference of pose (joint angles) between a neutral motion and the motion of a target attribute. In learning...
In speaker recognition tasks, the main reason for reduced accuracy is due to closely resembling speakers in the acoustic space. Conventional GMM-based modelling technique captures unique features along with common features among various classes. Further, it ignores knowledge of phonetic content of the speech. In order to increase the discriminative power of the classifier, the system must be able...
This paper describes an efficient framework for designing and developing Arabic speaker-independent continuous automatic speech recognition systems based on a phonetically rich and balanced speech corpus. The speech corpus contains 415 sentences recorded by 42 (21 male and 21 female) Arabic native speakers from 11 Arab countries representing three major regions (Levant, Gulf, and Africa). The developed...
In classification tasks, the error rate is proportional to the commonality among classes. Conventional GMM-based modeling techniques fail to capture the unique features of a class. Classification accuracy can be improved if the modeling technique is able to capture the unique features of each class. For any two models and their corresponding training data, the log-likelihoods may be assumed to be...
This paper presents a novel kernel density estimation approach to vehicle trajectory learning and motion analysis. The framework comprises a training stage and a testing stage. In the training stage, vehicle trajectories are first clustered by the hierarchical spectral clustering method. Then, through the proposed kernel density estimation approach, the average kernel density of one point on a trajectory...
This paper describes a speaker-independent accent-based natural language call-routing system. Based on a speaker's accent group, this system directs customer calls to the automatic speech recognition system that is most suitable to recognize the input query. The speech recognition system understands the caller's query and converts it into routing keywords. Accent identification is the most important...
This paper introduces an examination of several adaptation schemes for phone-based speaker verification. It is argued that different phonemes convey different amount of valuable information about speaker classification. Thus, the presented study tries to find more optimal settings to exploit this information. Experiments with short duration of training and testing of clean and telephone text-independent...
Keystroke dynamics refers to a userpsilas habitual typing characteristics. These typing characteristics are believed to be unique among large populations. In this paper, we present a novel keystroke dynamic recognition system by using a fusion method. Firstly,we record the dwell time and the flight time as the feature data. We then calculate their mean and standard deviation values and stored. The...
