[The use of voicing test in phoniatrics].
A study was made of the voicing-test efficacy in clinical practice. The study group consisted of 11 patients with different laryngeal diseases, the control group comprised 40 healthy subjects. Two parameters were estimated with a special computer soft: fraction of locally unvoiced pitch frames (FLUPF) and degree of voice breaks (DVB). Jitter, shimmer and signal to noise ratio were estimated as control. It is shown that the presence of locally unvoiced pitched frames is abnormal. The FLUPF test proved more precise than DVB test and, therefore, is preferential. Thus, the FLUPF test is clinically significant and can be used in clinical practice in line with parameters of acoustic analysis.
