This paper continues studies in the problem of animal’s language by registration of acoustic signals from the two quasi-stationary Black Sea bottlenose dolphins (Tursiops truncatus) using two-channel system in the frequency band up to 220 kHz with a dynamic range of 81dB. The packs of mutually noncoherent impulses dolphins (NI) were matched to the animals. The waveforms and the spectra of these impulses changed from one impulse to another one in each pack. In this connection, the suggestion was made that the set of spectral components of each impulse is a «word» of the dolphin’s spoken language and a pack of NI is a sentence. The paper studied the NI pecularities in the context of characteristics of a human spoken language.
