LPTV is located at Universidad de Chile and was founded by me in 2000. I will discuss the seminar work on uncertainty and how the first results were achieved. As far as we know, those are the first uncertainty modelling in HMM. I will talk about our experience with speech technology for telephone applications and second language learning. Some relevant papers on stochastic Weighted Viterbi, multi-classifier fusion, CAPT and VoIP will be discussed. I will describe our state-of-the-art robotic platform that we have implemented to pursue our research on voice-based human-robot interaction. In this context, the locally normalized features will be presented to address the time varying channel problem. I will show demos and discuss ideas on voice-based HRI. Finally, I will summarize our results on multidisciplinary research on signal processing. Biography: Néstor Becerra Yoma received the PhD degree from University of Edinburgh, UK, and the M.Sc. and B.Sc. degrees from UNICAMP (Campinas State University), Sao Paulo, Brazil, all of them in Electrical Engineering, in 1998, 1993 and 1986, respectively. From 2000, he has been a Professor at the Department of Electrical Engineering, Universidad de Chile, in Santiago, where he is currently lecturing on telecommunications and speech processing. In 2011 he was promoted to the Full Professor position. From 2016 to 2017 he was a visiting professor at CMU, USA. At Universidad de Chile he started the Speech Processing and Transmission Laboratory to carry out research on speech technology applications on human-robot interaction, language learning, Internet and telephone line. His research interest also includes multidisciplinary research on signal processing in fields such as astronomy, mining and volcanology. He is the author of about 40 journal articles, 40 conference papers and three patents. Professor Becerra Yoma was an associate editor of the IEEE Transactions on Speech and Audio Processing from for four years.
