I am an Assistant Professor with IST, Department of Electrical and
Computer Engineering , Universidade
Técnica de Lisboa. I am also a researcher at the Speech Processing Group of INESC.
Teaching
In the school year of 1999/2000 I am teaching Signal
Processing to undergraduates of the 3rd year of
Licenciatura em Engenharia Electrotécnica e de Computadores
and
Licenciatura em Engenharia Aeroespacial
.
Research
My research interests involve speech processing, particulary speech
synthesis, namely:
- Text-to-Speech synthesis for the Portuguese Language.
- Voice source modeling.
- Methods for automated voice source analysis.
Projects
I am currently involved in the following projects:
- SVIT
- Integration of speech processing
technology in the national
information service of Portugal
Telecom.
- DIXI
- Development of a text-to-speech system
for european portuguese. Our synthesizer currently runs on Unix
machines (SunOS, Linux, etc.) and on PC's running Windows95.
- DIXI+
- development of the DIXI system for Alternative and
Augmentative Communication.
Recently concluded projects:
- Speechdat
II
- Aquisition of a 4000 speaker database for
voice-driven teleservices. You can look at a sample
of the portuguese database.
Demos
If your computer is capable of playing audio files you can listen to
some demos of our work.
- Speechdat
II
- Sample recordings of the Portuguese Database.
- SVIT
- Speech synthesizer for telephone numbers.
- DIXI
- Portuguese text-to-speech synthesizer.
Other Info
- Phonetic Alphabet for European Portuguese
- Available in postscript ou em PDF, the table includes the phonetic
symbols in IPA format, in the PT-SAM ASCII representation, the
grapheme associated with each phoneme and a sample word.
