title: [Comparison of the results of acoustic analysis of the voice recorded by different methods].
abstract: This study was carried out with the purpose of estimating the possibility of the acoustic analysis of the voice recorded with the use of a handsfree telephone. The voices of 40 subjects were analysed with the help of the special software program. The recordings obtained with the help of the handsfree telephone and over a usual microphone were compared. The following parameters were determined: the frequency of the fundamental speech tone when reading a text and jitter, shimmer and the signal to noise (S/N) ratio when phonating the letter "a". Statistical analysis of the data obtained failed to reveal the significant difference between the values of the parameters of interest, such as the main the frequency, jitter, shimmer, and the S/N ratio, in both modes of recording (p>0.05).The results of the study confirm the possibility of acoustic analysis of the voice over the telephone.
