The effect of chosen parameters of a telephone channel on voice identification
The method and results of investigations aimed at the evaluation of the effect of chosen parameters of a telephone channel on the masking of the individual voice features are presented. In the experiments on voice samples of 10 speakers (men) a speech signal was represented by the amplitude correlation matrix and the distribution of time intervals between the zero-crossings of the speech signal. The effect of the frequency band of a telephone channel and of distortions deter¬mined by different signal to noise ratios on the probability of correct voice iden¬tification was investigated. The results obtained show the possibility of voice identification under the conditions of telephone transmission provided some definite values of the parameters of a telephone link are maintained.
