By using recorded speech, many of the voice qualities of the person recording the speech remain in the resulting synthetic ... recordings. The system’s intention is to make the process of recording a corpus of ut- terances relatively easy for those inexpe- rienced in linguistic anal...

We evaluate the performance of the cross-lingual text categorization, using both the BoW Kernel and the Multilingual ... do- main kernel. We can observe that the latter largely outperform a standard BoW approach. Analyzing the learning curves, it is worth noting that when the quanti...

By increasing the pool of ... We can use bagging (Breiman, 1996), a technique for generating a committee of classifiers, to assess the label uncertainty of a potential training instance. With...
