Dolphin Communication Techniques, or Dolcotec for short, is a non-profit organization founded in The Netherlands. Its aim to establish 2-way communication techniques with dolphins, through a combination of dedicated scientific research and inspirational art and games, as well as educating the general public about the rich cognitive, social and sensory lives of dolphins, which will ultimately help in their preservation.


Spotted dolphin Dolcotec’s main mission is to make 2-way communication between humans and dolphins a reality within the foreseeable future (see also our Mission statement).  We realize this may sound as a big challenge to achieve, but we believe this should be possible in principle, given the large body of scientific research findings on dolphin intelligence and communication pointing in that direction, as well as earlier dolphin language work done from the sixties through nineties (see Background).  Also, the exponential growth in available computing power and speed that the world has seen in recent years, and especially the spectacular recent advances in AI with powerful tools such as Machine Learning and Deep Learning, makes a project of this order likely to succeed in this day and age.

Apollo 11 lift-offFrom our perspective, what is needed is a scientific effort similar in courage, imagination, and vision as the Apollo project in the 1960s.  Why this analogy?  Before the space age, the idea of ever jumping around on the Moon was considered as a pipe dream to achieve – until a focused dedication of resources, the brightest minds and above all a strong will and belief to make it happen, brought it into reality.  Likewise, when it comes to intelligent communication with another Kennedy's 1962 moon speech species, the prevailing paradigm, at least until recently, has been that this was considered as outside the realm of conventional science – but this attitude is now changing.  So to paraphrase John F. Kennedy’s famous words in his 1961 speech, “to achieving the goal, before this decade is out, of landing a man on the Moon” – let’s commit ourselves to achieving the goal, before the decade is out, of communicating with dolphins!

Dolcotec has the philosophy that utilizing the scientific method as well as the latest available technology will play an essential role in achieving success, but will not be sufficient in and of itself.  In our view, this left-brain, analytical and objective approach needs to be complemented and counter-balanced by a more right-brain, holistic and subjective approach.  After all, young children do not learn language by us using the scientific method to teach it to them, but simply by using language around them and engaging them all of the time.

Akrotiri dolphins in Knossos palaceOur logo, as well as our name “Dolphin Communication Techniques” reflect this philosophy and approach.  The word “Technique” originates from the ancient Greek word “τέχνη” (techne), which means as much as art or craftsmanship.  It’s a practical skill used to accomplish a certain goal or objective.  We chose the word techniques rather than technologies, because creating specific technologies is not a goal in itself, but rather a helpful means to the end of communicating with dolphins.  Also, the word technology implies a rather analytical, cold, and distanced approach, while technique implies complete engagement using both one’s head and heart, which we believe will both be key to success.  Our Dolcotec team consists of scientists, naturalists, and film-makers (see Who we are), thus representing a good mix of analytical and creative capacities.


A similar complementary approach can be recognized in the two research pillars (see Projects) that Dolcotec is built on:

  • On the one hand, our long-term goal to establish an artificial language with domesticated dolphins through intermediary computer software (see GAPR);
  • And on the other hand, to study the natural communication used by dolphins in the wild (see 4-channel UDDAS).

GAPR / General Audio Pattern RecognizerWe believe these two projects will complement and benefit from each other, as gaining insights and good high-frequency recordings from dolphin communication in the wild will help in setting up a better artifical language, and vice versa: finding out what works and doesn’t work in an artifical language will give us better clues as to how to decipher wild dolphin vocalizations.

So besides scientific research, Dolcotec is also fully committed to public outreach, in order to raise awareness of dolphins, dolphin intelligence and our seas and oceans.  This can be done through lectures, both to the general public and at schools.  Please contact us if you have any requests in that regard, or for any other questions that you might have.  We are of course also very appreciative of any donations that you might be willing to make, and which are completely tax-deductible:  Dolcotec has been granted the official charity status (“Algemeen Nut Beogende Instelling”, or ANBI) in The Netherlands.
