Speech and Dialogue (SpeeD) Laboratory is a teaching and research laboratory within University “Politehnica” of Bucharest. SpeeD Lab was founded in 1984 by Professor Corneliu Burileanu, who is also the leader of the laboratory ever since. SpeeD Lab’s staff is currently composed of 4 full-time academic members (2 full professors and 2 lecturers) and several PhD and master students.
SpeeD Laboratory is located in the Faculty of Electronics, Telecommunications and Information Technology (ETTI), where it uses several multi-functional rooms (three research/meeting offices and two teaching/research laboratories). The teaching/research laboratories can accommodate more than 60 students and are equipped with PC workstations, several high-performance processing servers and graphical workstations, networking hardware, professional audio recording/playback devices, measurement and analysis equipments, general and proprietary hardware platforms, software development tools and dedicated software applications, multimedia facilities for teaching and presentations, etc.
SpeeD Lab’s staff is dedicated to academic teaching and scientific research at bachelor, master and doctoral level in various fields at the confluence of electronics, signal processing and information technology. SpeeD Lab’s staff is teaching several courses within ETTI Faculty, among which the most important are: Microcontrollers and Microprocessors Architectures, Spoken Language Technology, Digital Signal Processing and Computer Programming. Furthermore, from 2011 the group coordinates the two-years BIOSINF master programme (“Multimedia Technologies in Biometrics and Information Security Applications”).
SpeeD Laboratory is one of the leading speech research groups in Romania, with many significant contributions to the development of spoken language technologies, among which the most important are:
- the first small vocabulary isolated words recognition system for Romanian (1986);
- an early version of a complete Voice over IP (VoIP) system (1994-1995, see the Proceedings of “ICSPAT” Conference, Boston, USA, 1995);
- the first version of a Text-to-Speech (TTS) synthesis system in Romanian (1998);
- the first Large vocabulary Continuous Speech Recognition (LVCSR) system for Romanian (2011).
The Speech and Dialogue Laboratory is currently concerned with scientific research in:
- all areas of Spoken Language Technology (SLT), including:
- Automatic Speech Recognition (ASR) and Text-to-Speech (TTS) synthesis
- Speaker Recognition
- Spoken Term Detection (STD), Spoken Document Indexing/Retrieval
- Natural Language Processing (NLP), including Language Modeling (LM)
- Digital Signal Processing (DSP)
- Statistical Machine Translation (SMT)
Since its foundation, SpeeD has coordinated and was involved in numerous national and international research projects (including collaborations with Laboratoire d’Informatique de Grenoble, Institut de la Communication Parlée de Grenoble, Télécom ParisTech, Ecole Polytechnique Fédérale de Lausanne) and industrial projects (including collaborations with Softwin R&D Group Romania, Freescale Semiconductor Romania, Microchip Technology Romania). It has successfully implemented over 23 private and national research grants. SpeeD group holds more than 10 Romanian issued patents and its members have authored more than 250 books, book chapters and journal/conference papers.
