On the connection of some time characteristics of speech signal with the individuality of voice

Various speech signal time characteristics are estimated from voice individuality data transmission standpoint. Speech wave microtime intervals (that is the intervals between the zero-cross and extremal points and the intervals of fundamental tone) are taken as such characteristics from one hand, and macrotime structure of the signal which comprises some prosodic properties of pronunciation from the other hand. Statistical analysis of the above speech signal parameters has shown that the majority of them are closely connected with the individuality of voice. However, these parameters being used for automatic identification of speakers it should be noted that some of them can be controled by speakers and therefore imitated.
