Abstract : The sound producing mechanisms in the bottlenose dolphin (Tursiops truncatus) operate naturally underwater with a closed blowhole. In these experiments Tt's reprogrammability in the vocal airborne mode and in vocal-ascoustic interlock with another species is demonstrated. Human speech output programs were constructed from randomized vowel-consonant (V-C) and consonant-vowel (C-V) lists and simple English words and phrases. The analysis of the dolphin's sonic vocal output in response to these Hs vocal programs demonstrates Tt's reprogramming: in matching number of trains of bursts, interburst silences, and latencies; ability to differentiate between Hs stimuli and other Hs comments or corrections, and ability to program from natural delphinic sounds to 'humanoid' emissions.
