摘要:
An automated emotional recognition system includes an emotional state classifier adapted to receive, during an operative phase, an input information stream with embedded information related to emotional states of a person, and to generate a succession of emotional state indications derived from the input information stream. The emotional recognition system further includes a post-processing function, configured to receive at least two emotional state indications of the succession and, for each of said at least two emotional state indications, determine a corresponding emotional state representation in an emotional state representation system. The post-processing function is further configured to combine the emotional state representations of the at least two emotional state indications to obtain an output emotional state indication.

A method of transmitting speech data to a remote device in a distributed speech recognition system, comprising the steps of : - dividing an input speech signal into frames; - calculating, for each frame, a voice activity value representative of the presence of speech activity in said, frame; - grouping the frames into multiframes, each multiframe comprising a predetermined number of frames; - calculating, for each multiframe, a voice activity marker representative of the number of frames in said multiframe representing speech activity; and - selectively transmitting, on the basis of said voice activity marker associated to each multiframe, said multiframes to said remote device.
摘要:
An automated emotional recognition system is adapted to determine emotional states of a speaker based on the analysis of a speech signal. The emotional recognition system includes at least one server function and at least one client function in communication with the at least one server function for receiving assistance in determining the emotional states of the speaker. The at least one client function includes an emotional features calculator adapted to receive the speech signal and to extract therefrom a set of speech features indicative of the emotional state of the speaker. The emotional state recognition system further includes at least one emotional state decider adapted to determine the emotional state of the speaker exploiting the set of speech features based on a decision model. The server function includes at least a decision model trainer adapted to update the selected decision model according to the speech signal. The decision model to be used by the emotional state decider for determining the emotional state of the speaker is selectable based on a context of use of the recognition system.

An arrangement for secure user authentication includes a computer or telecommunication terminal with a smartcard and a device. The smartcard is adapted to securely store biometric information relating to at least one user and the device is adapted to detect biometric data of users. The smartcard and the device include a radio interface for communicating together and a module for exchanging biometric information between each other. In this way, tampering of the transferred biometric information is difficult. In order to increase the security, one or more of the following measures may be used: a secure communication channel between the device and the smartcard, a direct (preferably short range) communication channel between the device and the smartcard and encryption and decryption of biometric information transferred between the device and the smartcard.
