Unsupervised evaluation of speaker verification systems
A method for blind estimation of DET curves for speaker verification systems is proposed. Verification error probabilities are estimated on a database where speaker identities are unknown. The database must provide a set of impostor-only tests as well as a set of mixed impostor and target tests. This method is tested on 9 speaker verification systems that were scored on the NIST 2000 database. ...
متن کاملautomatic verification of authentication protocols using genetic programming
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
15 صفحه اولUsing Exciting and Spectral Envelope Information and Matrix Quantization for Improvement of the Speaker Verification Systems
Speaker verification from talking a few words of sentences has many applications. Many methods as DTW, HMM, VQ and MQ can be used for speaker verification. We applied MQ for its precise, reliable and robust performance with computational simplicity. We also used pitch frequency and log gain contour for further improvement of the system performance.
متن کاملImproving the Performance of Speaker Verification Systems in Noisy Environments
Classical speech enhancement techniques and recently developed wavelet denoising schemes are applied to speaker verification systems in noise. Merely applying these techniques to corrupted testing signals does not properly decreases the error rates when clean speech is used for training signals. In this paper, a noise modelling approach is used to corrupt the training signals according to an es...
