BUSIM / SPG: Speech Processing Group

BUSIM / SPG: Speech Processing Group

The speech group at Boğaziçi University was initiated in year 1998 as Dr. Arslan joined the department from Entropic Research (later acquired by Microsoft). In year 2005, Dr. Murat Saraclar joined the group from AT&T Labs Research. Currently there are 6 PhD and 2 MSc students actively working on speech processing research. Main topics include large vocabulary continuous speech recognition, voice conversion, 3-D audio-visual synthesis, speech synthesis, speech therapy and speaker identification. Until now 2 PhD dissertations and 17 MSc theses have been completed by the group members. The courses related to speech research at the department are as follows:

Speech Processing, Psychoacoustics, Automatic Speech Recognition, Advanced Speech Processing, Statistical Natural Language Processing.

The group is involved in two European Union Network of Excellence projects, namely SIMILAR and BIOSECURE. Aside from the cooperation with the partners of those projects, there is active collaboration with Boğaziçi University Linguistics Department, Istanbul Cerrahi Hospital, and Anadolu University Speech Therapy Center. The spin-off
speech research company from the group, SESTEK (www.sestek.com.tr), has products based on speech recognition, speech synthesis and voice conversion technology.
