Test Generation for Duration Systems

We are interested in generating tests for duration systems modeling real-time systems. The specification of a duration system is given as a duration graph. Duration graphs are an extension of timed graphs and are suitable for modeling the accumulated times spent by computations within the considered duration system. In this paper, we present a method for generating tests for duration systems ba...

Model compensation for noises in training and test data

It is well known that the performances of speech recognition systems degrade rapidly as the mismatch between the training and test conditions increases. Approaches to compensate for this mismatch generally assume that the training data is noise-free, and the test data is noisy. In practice, this assumption is seldom correct. In this paper, we propose an iterative technique to compensate for noi...

Bidirectional Modelling for Short Duration Language Identification

Language identification (LID) systems typically employ ivectors as fixed length representations of utterances. However, it may not be possible to reliably estimate i-vectors from short utterances, which in turn could lead to reduced language identification accuracy. Recently, Long Short Term Memory networks (LSTMs) have been shown to better model short utterances in the context of language iden...

Content matching for short duration speaker recognition

This work attempts to tackle the problem of content mismatch for short duration speaker verification. Experiments are run on both text-dependent and text-independent protocols, where a larger amount of enrollment data is available in the latter. We recently proposed a framework based on a deep neural network that explicitly utilizes phonetic information, and showed increased performance on long...
