The Institute for Experimental Phonetics and Speech Pathology (IEPSP) was founded in 1949 by Professor Djordje Kostic,

worldly renowned linguist, phonetician, painter and poet. Until his death in 1995, together with the collaborators from the Institute, Professor Kostic worked on the development of

scientific-research work in the area of sound, hearing, speech and language and applied achieved results in different areas:

medicine, linguistics and electroacoustics.

Cherishing the tradition of multidisciplinary knowledge and concept of work organization, the Institute carries out

scientific-research and expert work in the areas of experimental phonetics, electroacoustics, speech and language

development, pathology of hearing, speech and language, learning Serbian as a foreign language and promotion of 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.

HEALTHHEALTH CARECARE - by application of scientific results, IEPSP has developed biomedical engineering in the areas of sound, hearing, speech and language, based on the holistic approach, as well as an integrative treatment of verbal communication pathology. This approach resulted in the development of a unique KSAFA system (Kostic’s selective auditory filter amplification) for early detection, diagnostics and habilitation of speech and language in children with hearing impairment, undeveloped speech, speech and language pathology, cognitive development disorders and behavioural 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. Within the KSAFA system, sophisticated diagnostic procedure is conducted. Depending on a child’s age, it implies the application of: prenatal hearing screening, establishing risk factors in pregnancy, OAE, bacteriological tests, biochemical analyses, metabolic tests, food intolerance tests, EEG in mapping tasks, impedancemetry, tonal audiometry, ksafametry, battery of IEPSP tests for the period from birth to adolescence.

IEPSP is the institution which covers IEPSP is the institution which covers the activities of national importance the activities of national importance

in the following areas:in the following areas:

Integrative treatment implies application of precise procedures of audiolinguistic treatments by KSAFA apparatuses. One of the basic principles is strictly individual approach in the planning and conducting the treatment, from prenatal early stimulation to the complete development of verbal communication. Children’s treatment implies continuous education of parents for the development of speech-language competence in children and offering full support to their work. As a support to audiolinguistic treatment additional technologies were introduced: bio and neuro feedback, Schwartz’s method for stuttering treatment, hygiene-nutrition regime for certain types of speech-language pathology, as well as administering defined neuropeptide complexes (''Audioinvit'' and ''Aktoinvit'') In 98% children with different degree of hearing impairment (30-120 dB), children with undeveloped speech, different types and degrees of impairment, different types and degrees of speech pathology, speech and language are developed to the level of normal communication and children are included in regular primary schools. The Institute developed the method of prenatal hearing screening which enables detection of hearing development disorder in fetus in the 7th month of pregnancy.

SCIENCESCIENCE--IEPSPIEPSP conducts multidisciplinary, fundamental, applied and developmental researches of hearing, speech and language in normal and pathological states, from the cell level up to corpus linguistics, from prenatal period to adulthood. Results of technological projects provided: - 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.

CULTURECULTURE – In IEPSP, decades of devoted work resulted in the Corpus of Serbian Language (CSL), in electronic form, which presently has 11 11 million words, and is still being expanded, thus representing the largest grammatical manually tagged corpus in the world and the only diachronic corpus in the world spanning the period from XII to XX century. Owing to the CSL, 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.

EDUACATIONEDUACATION - IEPSP has programs for the application of

KSAFA system for pre-school and primary school teachers,

defectologists, pediatricians, psychologists and other experts

dealing with children’s development. At the same time, it

organizes education of parents who have children with special needs.

Being scientific-educational basis, IEPSP takes part in the

education of students of the Faculty for special education and

rehabilitation of Belgrade University, thus contributing to cherishing future scientists and

experts.

IEPSPIEPSP organizes education of foreign and domestic experts for the application of KSAFA system in clinical practice and special schools. IEPSP issues 3-year valid certificates and performs the procedures of recertification.

IEPSPIEPSP organizes learning and improvement of Serbian as a foreign language.

IEPSPIEPSP collaborates with a number of institutions and eminent experts in the country and abroad (Greece, Russia, Germany, Sweden, Norway, Italy, Bulgaria, Belarus, Poland etc).

The First European Congress on the prevention, detection and diagnostics of verbal communication disorders in children was held in 2006. It will be held every second year in a different country with the aim of taking adequate measures and activities for the prevention of increasing speech-language pathology at an early age, as well as behaviour and learning disorders.

IEPSPIEPSP possesses an international and domestic certificate IQnet, ŐQS and Eurocert for the system of quality management according to JUS ISO 9001:2001 standards.

IEPSPIEPSP – 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 presented plenary, providing the essential multidimensional exchange of knowledge and realization of further research directions in the areas of hearing, speech and language.
