In this paper, we propose a new feature selection scheme that can contribute to an ICA-based feature extraction block for speech recognition. The initial set of speech basis functions obtained in independent component analysis training phase, has some redundancies. Thus, finding a minimal-size optimal subset of these basis functions is rather vital. On the contrary to the previous works that us...

Previous works on speech recognition utilizing neural networks have often relied on either recognition through segmentation or mapping of the representation trajectories to the phoneme space. Here, information could be missed due to the manner of border labeling techniques. Recent works have indicated that firstly, phonetic borders and transitions would have a good potential to be recognized as...

Setup of an emotion recognition or emotional speech recognition system is directly related to how emotion changes the speech features. In this research, the influence of emotion on the anger and happiness was evaluated and the results were compared with the neutral speech. So the pitch frequency and the first three formant frequencies were used. The experimental results showed that there are lo...

BACKGROUND The use of the internet as a source of information gathering, self-help and support is becoming increasingly recognized. Parents and professionals of children with hearing impairment have been shown to seek information about different communication approaches online. Cued Speech is a very new approach to Persian speaking pupils. Our aim was to develop a useful website to give related...

Stress is known to be an important prosodic feature of speech. The recognition of stressed speech has always been an important issue for speech researchers. On the other hand, providing a large corpus with the coverage of all different stressed conditions in a certain language is a difficult task. Farsi (Persian) has been no exception to this. In this research, our aim has been to evaluate the ...
