How would we type their speech patterns vs ours? Different frequency ranges? Speed? Cadence? ... Here is the only bit I can remember from cross-human language comparison, not cross-species: https://en.wikipedia.org/wiki/Speech_tempo https://en.wikipedia.org/wiki/Speech_tempo (searched: different languages speaking rate) (Edit: information density and speech rate) So my first question is about types of "spoken languages"? --- from searching, "types of languages" "click languages": * African languages and linguistic typology - https://www.acsu.buffalo.edu/~jcgood/jcgood-AfricaTypology.pdf https://www.acsu.buffalo.edu/~jcgood/jcgood-AfricaTypology.p... * Language Classification: History and Method - https://edisciplinas.usp.br/mod/resource/view.php?id=2225588 https://edisciplinas.usp.br/mod/resource/view.php?id=2225588 Anyone have a speech-to-text and POS-tagger yet for dolphins' language morphology/-ies? --- Deciphering the Dolphin Language - http://neuronresearch.net/dolphin/pdf/Dolphin_language.pdf http://neuronresearch.net/dolphin/pdf/Dolphin_language.pdf An assumption can be made that the CNS of the dolphin employs a frame time similar to humans, nominally 30 milliseconds. As a starting point, it is reasonable to assume that a typical phoneme is three to five times longer than 30 ms based on experience with human languages. A complication arises because of the multiple sources of sound within the dolphin’s nasal passages, recalling that the larynx of the dolphin is not in its throat (the passage along which food is ingested). These multiple acoustic sources suggest the dolphin can achieve an equivalent of the unique “throat singing” of the Inuit and Tuva people of Asia. Throat singing is also known as overtone singing. Wikipedia provides a good description of throat singing. In Dolphin, the equivalent is clearly nasal singing. Nasal singing in dolphin may be even more extensive. As a starting point, the acoustic range of dolphin sounds (other than its forward focused echolocation sounds) potentially useful in communications (language) extends from about 2000 Hz to at least 80,000 Hz (with whistles extending up to about 40,000 Hz). In seeking to understand Dolphinia or Truncates, it makes no sense to restrict our analyses to frequencies that the human can hear. Nor is it rational to limit the dolphin’s language to either a tonal or a stressed structure. --- Interpreting the acoustic pulse emissions of a wild bottlenose dolphin - http://aquaticmammalsjournal.org/share/AquaticMammalsIssueArchives/1988/Aquatic_Mammals_14_1/Goodson.pdf http://aquaticmammalsjournal.org/share/AquaticMammalsIssueAr...

I hope some researcher(s) will put out organized videos of dolphins chatting alongside audio spectrograms. Remember the Enigma story, every message had certain words in it and was likely to have certain ones in certain places at certain times from certain senders to certain receivers... Certainly.

The role of larynx in cetacean sound production is still debated, but we do know that they posses at least 2 sound generating mechanisms that could work independently and simultaneously. It appears that right side phonic lip is involved in echolocation and pulsed sounds, the right one is involved in whistling. Two (maybe even 3, if larynx is indeed invoved too) sound producing mechanisms make their communication even more complex, since it greatly increases the sound combinations probabilities. Many researchers have already done that, i.e. using video and audio for sound analysis, and here we are,60+ years later, still do not know the function of even a single call, apart, of course, from signature whistles and echolocation. This is a non-human communication system, 25 mln years in the making by creatures who rely on sounds in ways humans never will. When we study cetaceans, we struggle to determine who produces the sound, who responds, even tagged animals are problematic, because the sound could be made by someone next to them. In large pelagic pods, it is a cacophony, they chat all the time and never shut up. It appears that at least in dolphins, whistles could be more of a long distance signals, but pulsed ones, like burst pulses, are more of a short distance signals, for those who are close by. But make no mistake, some information is being transmitted, we know that. The Bastian experiment with all its flaws was first to demonstrate it,and it has been replicated too. Some researchers are not entirely convinced, but it is definitely a very interesting area to explore.
