pages 428 - +6p., full text

After the phoniatric examination the tape-recording of voice was carried out on 14 patients (6 male, 8 female, age from 16 to 39 years) in a studio. The second recording was performed approximately 1 month after tonsillectomy. Patients phonated five Czech vowels /a:/, /e:/, /i:/, /o:/, /u:/. The acoustic analysis was performed by Multi-Dimensional Voice Program and the position of the first four formants was evaluated. The finite element (FE) models of the acoustic spaces corresponding to the human vocal tract for the Czech vowels /a:/ and /i:/ were used in the mathematical modelling. The acoustic resonant characteristics of the FE models were studied by modal and transient analyses. The acoustic analyses were realised by the software code SYSNOISE.
