This paper presents a real-time method for Spoken Language Identification based on the entropy of the posterior probabilities of language specific phoneme recognisers. Entropy based discriminant functions computed on short speech segments are used to compare the model fit to a specific set of observations and language identification is performed as a model selection task. The experiments, perfo...

A completely automatic identification system is described which uses the latest results of the frequency domain identification approach to provide an easy-to-use and reliable tool to the inexperienced users. The proposed system accepts periodic measurement data and performs the whole identification procedure automatically from the data-preprocessing step to model and parameter selection. The va...

Proportionate type adaptive filtering (PtAF) algorithms have been successfully applied for sparse system identification. The major drawback of the traditional PtAF based on the mean square error (MSE) criterion is poor robustness in the presence of abrupt changes because the MSE is valid and rational under Gaussian assumption. However, this assumption is not satisfied in most real-world applica...
