2. Institute for Experimental Phonetics and Speech Pathology I E P S P The Institute for Experimental Phonetics and Speech Pathology (IEPSP) was founded in 1949 by Professor Djordje Kostic, worldly renowned linguist, phonetician, painter and poet.Untilhisdeathin 1995, togetherwiththecollaboratorsfromtheInstitute, ProfessorKosticworkedonthedevelopmentofscientific-researchworkintheareaofsound, hearing, speechandlanguageandapplied achieved results in different areas: medicine, linguistics and electroacoustics. Djorje Kostic Cherishing the tradition of multidisciplinaryknowledge and concept of work organization, the Institutecarries outscientific-research and expert work in the areas ofexperimental phonetics, electroacoustics, speech and language development, pathology of hearing, speech and language, learning Serbian as a foreign language and promotionof the culture of speech and language, whose results do not have only therapeutic significance, but are also practically applied in different scientific and expert areas. Director of the Institute for Experimental Phonetics now is Mirjana Sovilj. Mirjana Sovilj

3. IEPSP is the institution which covers the activities of national importance in the following areas: HEALTHCARE - byapplicationofscientificresults, IEPSPhasdevelopedbiomedicalengineeringintheareasofsound, hearing, speechandlanguage, based on the holistic approach, as well as an integrative treatment of verbal communication pathology.This approachresulted in thedevelopment ofauniqueKSAFAsystem (Kostic’sselectiveauditoryfilteramplification) forearlydetection, diagnosticsandhabilitationofspeechandlanguageinchildrenwithhearingimpairment, undevelopedspeech, speechandlanguagepathology, cognitivedevelopmentdisordersandbehavioural and learning disorders from fetal period (before birth) up to 10 years of age. The application of KSAFA system prevents disability in children and encourages the development of healthy posterity. WithintheKSAFAsystem, sophisticateddiagnosticprocedureisconducted.Dependingonachild’sage, it impliestheapplicationof: prenatalhearingscreening, establishingriskfactorsinpregnancy, OAE, bacteriologicaltests, biochemicalanalyses, metabolictests, foodintolerancetests, EEGinmappingtasks, impedancemetry, tonalaudiometry, ksafametry, batteryofIEPSPtestsfortheperiodfrombirthtoadolescence.

SCIENCE-IEPSP conductsmultidisciplinary, fundamental, appliedanddevelopmentalresearchesofhearing, speechandlanguageinnormalandpathologicalstates, fromthecellleveluptocorpuslinguistics, fromprenatalperiodtoadulthood. Resultsoftechnologicalprojectsprovided: - development of prenatal hearing screening and accompanying equipment - new generations of KSAFA apparatuses, which very precisely dose sound according to the type and degree of speech and language disorder and/or hearing impairment and behaviour and learning disorder. - development of apparatuses for otoacoustic emission (ТЕОАЕ and DPОАЕ screening). Among other things, it is applied in the detection of hearing impairment in babies immediately upon birth. - development of expert system for the assessment of pathological forms of sound articulation etc.

6. CULTURE – InIEPSP, decades of devoted work resulted in theCorpus of Serbian Language (CSL), in electronic form, which presently has 11 11 million words, and is still being expanded, thus representingthe largest grammatical manually tagged corpus in the world and the only diachronic corpus in the world spanning the period from XII to XX century. OwingtotheCSL, frequency dictionaries by different authors have been compiled. It also inspired an increasing number of researches in the areas of language studies and statistical linguistics. IEPSPorganizeseducationofforeignanddomesticexpertsfortheapplicationof KSAFA system inclinicalpractice and specialschools. IEPSPissues 3-yearvalidcertificatesand performs the procedures ofrecertification. IEPSPorganizes learning andimprovement ofSerbian as a foreign language. IEPSPcollaborateswithanumberofinstitutionsandeminentexpertsinthecountryandabroad (Greece, Russia, Germany, Sweden, Norway, Italy, Bulgaria, Belarus, Polandetc). EDUACATION - IEPSPhasprogramsfortheapplicationofKSAFAsystemforpre-schoolandprimaryschoolteachers, defectologists, pediatricians, psychologistsandotherexpertsdealingwithchildren’sdevelopment. At the same time, it organizes education of parents who have children with special needs.

7. In 2005, IEPSPandAll-Greekorganizationforcommunicationdisordersandtherapy – P.A.L.Osignedthefraternization Charterand initiated foundation of international organization for prevention of verbal communication disorders in children. The First European Congress on the prevention, detection and diagnostics of verbal communication disorders in childrenwas held in 2006. It will be held every second year in a different countrywith the aim of takingadequate measures and activities for the prevention of increasingspeech-language pathology at an early age, as well as behaviour and learning disorders. IEPSP possesses an international and domestic certificate IQnet, ŐQSandEurocert for the system of quality management according toJUS ISO9001:2001 standards. IEPSP– initiated and organized International scientific conference «Speech and language»(1999,2004, 2007....),whose concept and organization is unique in the world because all the papers from 10 scientific areas are presentedplenary, providing the essential multidimensional exchange of knowledge and realization of further research directions in the areas of hearing, speech and language.
