Rubén San-Segundo received his MSEE degree from Technical University of Madrid in 1997, and Ph.D. degrees from the same university in 2002 (with highest distinction). From 1997 through 2001, Rubén was supported under an Education Ministry Grand. During his PhD, his research included: speech recognition of spelled words, confidence measures estimation for speech recognition and understanding, and dialogue design for speech applications.


During 1999 and 2000, Ruben did two summer stays in The Center of Spoken Language Research (CSLR) at the University of Colorado (Boulder), as visiting PhD student. During these stays, he worked in confidence measures at the CU Communicator System.


From Sep. 2001 through Feb. 2003, Rubén worked at the Speech Technology Group of the Telefónica I+D. During this period, he worked in confidence estimation for speech recognition, acoustic modelling of speech, and he was involved in the design of several services considering these technologies. Ruben collaborated in the definition of proposals for new research projects.


From Mar, 2003 through Mar. 2004, Rubén worked at the Electronic Systems and Control Department at the EUITT of UPM, and then, he moved to the Electronic Engineering Department. Rubén has been academic secretary and vice-director of the Electronic Engineering Department.


Rubén has been the Coordinator of the Spanish Network on Speech Technologies ( and vice-chair of the Special Interest Group of ISCA on Iberian Languages ( Rubén has been the Principal Investigator of the project: “Speech in to Sign Language Translation” ( Rubén has participated in more than 20 research projects (being the PI in 8 of them) publishing more than 100 papers (more than 50 in JCR journals). He has supervised 2 PhD theses and more than 25 Master theses.


Rubén has got a MECD/ Fulbright grant for a postdoctoral stay at the Human Sensing Laboratory at the Robotics Institute in Carnegie and Mellon University.


Currently, Rubén is full professor at the department of Electronic Engineering at ETSIT of UPM, vice-director of the Information Processing and Telecommunication Center (IPTC), coordinator of the Bsc in Data Engineering and Systems and member of the Speech Technology Group (GTH) at the ETSIT. His research interests are: speech technology, assistive technologies for disable people (Sign Language) and human sensing technologies.
