Speech and Language Technologies Laboratory

-A +A

ISO and NATO certified semi-anechoic acoustic recording and test rooms are Turkey’s first and only “Voice and Speech Technology Evaluation” infrastructure.

In this infrastructure, two specially insulated semi-anechoic acoustic recording room (20 and 18 m2 area) and again a specially insulated listener test room (91 marea) exists. In this test room, 16 subjects can actively participate  the assessment simult aneously. All kinds of audio technology developed for military and civilian purposes can be evaluated in this  infrastructure with the help of simulations of various acoustic environments.

Listener room can be used as a “Human Factors Laboratory” with thanks to its silent terminals and touchable monitors.
