In this thesis, an analysis was made of instrumental experimental methods used in international congresses of phonetic sciences on predetermined criteria: international participation, longevity and consisting of papers using instrumental techniques. Only physiological techniques were taken into account divided into well-established sub-groups: acoustic method, method of visual representation (X-ray, CT, MRI and ultrasound), flesh-point tracking method (electromagnetic articulography), tongue-palate interaction (electro/palatography) and method of muscle activity measurements (electromyography). Their historical development was briefly explained and every method was elaborated in the context of its current use. The following conferences were are International Congress of Phonetic sciences in a period of the last ten years, conference on Speech motor control in a period of the last thirteen years and ultimately conferences organized by International clinical phonetics and linguistics association in a period of the last twelve years. In total, around 1600 scientific papers and abstracts were examined, covering on over 4500 pages of text. Quantitative analysis showed a large predominance of acoustic method, followed by method of visual representation and flesh-point tracking with tongue-palate interaction method and muscle activity measurements in the smallest percentage.
