In this paper an approach based on the use of different frame lengths for the feature extraction process in the training and recognition phases of a speaker verification system is presented. It is able to sensibly reduce the ER and the degradation on performance related to the training/verification feature mismatch. The potentiality of the approach are investigated in an a-posteriori search of ...

In this paper a new framework for acoustic model building is presented. It is based on non-uniform segment models, which are learned and scored with a time bidirectional recurrent neural network. While usually neural networks in speech recognition systems are used to estimate posterior "frame to phoneme" probabilities, they are used here to estimate directly "segment to phoneme" probabilities, ...

Background and Objectives: Action recognition, as the processes of labeling an unknown action of a query video, is a challenging problem, due to the event complexity, variations in imaging conditions, and intra- and inter-individual action-variability. A number of solutions proposed to solve action recognition problem. Many of these frameworks suppose that each video sequence includes only one ...

this paper is a continuation of [uniformities and covering properties for partial frames (i)], in which we make use of the notion of a partial frame, which is a meet-semilattice in which certain designated subsets are required to have joins, and finite meets distribute over these. after presenting there our axiomatization of partial frames, which we call $sels$-frames, we added structure, in th...

Providing high quality video transmission in VANETs is very challenging due to the highly dynamic, unpredictable topology, and low bandwidth characteristics. In this article, we design a system able optimally transmit RTP streams an IP-based multihomed VANET. By splitting through its different frame types array of paths from center node network clients, can then send critical frames, depending ...

The evolution of quantum states in a relativistic scenario is meaningful and practically relevant problem the framework physics simulation noninertial frame. Here, we investigate roles effect induced by two relatively accelerated bosonic observers on speed system coupled with amplitude damping channels. We find that speed-up damped to uniform for strength p ? ? c 0 , where critical parameter be...
