Sérgio Paulo graduated in Electrotechnical Engineering from Instituto Superior Técnico ([1]) of the Technical University of Lisbon, in 2001. He is a PhD student on Corpus-based Speech Synthesis at L2F since December of 2001. His current research interests are corpus design, automatic phonetic alignment techniques, pronunciation modeling and automatic building of annotated linguistic databases. His current efforts are being spent on speeding up the creation of synthetic voices for any speaker.
