Trying to speak to the animals? Might be tougher than we thought!

Speaking with the animals may not be that easy

The fascination with understanding the cognitive processes of animals dates back to ancient times. The concept of animals possessing the ability to communicate or even speak has been ingrained in various cultures across the world. This notion extends from Greco-Roman literature, where animals frequently converse, to indigenous storytelling traditions in places like India, Egypt, and Native America. Even in contemporary Western culture, the idea of talking animals persists, often depicted through technology-aided speech rather than supernatural means. This concept is evident in pop culture with examples like the dolphins communicating through advanced translation devices in shows like “Seaquest DSV” and “Johnny Mnemonic,” and Dug the dog from “Up.”

More complex than we thought

While machine-learning systems and natural language processors have made substantial progress in translating human speech into numerous languages, adapting these technologies to decode animal communication is a more complex endeavor. The belief that “all living things communicate” forms the basis for exploring this field, as stated by an interdisciplinary team of researchers in the 2018 study “On understanding the nature and evolution of social cognition: a need for the study of communication.” This communication involves influencing behavior, behavior tendencies, or physiology in another individual in an adaptive manner. This assertion applies across the spectrum of living organisms, from microbes and fungi to plants and beyond. However, it is important to distinguish between “communication” and “language.”

The Linguistics Society of America notes that while communication is inherent in various forms among living beings, human language stands apart due to its unique characteristics. Language enables the expression of inner thoughts, the conveyance of information, and the ability to make requests or demands. Unlike other animal communication systems, language includes elements like negation, allowing expression of what is not the case. Animal communication systems, in contrast, tend to consist of only a few dozen distinct calls that address immediate issues like food, danger, threats, or reconciliation.

Still a mystery

Although pets like dogs and cats can respond to specific human words, the extent to which they truly understand the meaning behind these words remains a question. Dr. Monique Udell, Director of the Human-Animal Interaction Laboratory at Oregon State University, explains that associations are often learned through basic conditioning. While dogs, for instance, can learn to respond to over 1,000 human words with high accuracy, it is challenging to determine whether they grasp the intention behind those words or actions. Understanding the intent often hinges on observing a pet’s behavior in response to stimuli.

Natural Language Programming (NLP) serves as the AI branch enabling computers to interpret text and speech. NLP combines computational linguistics and machine-learning models to understand human language intent. NLP underpins digital assistants’ functionality, translating human speech into machine-understandable signals and vice versa.

The evolution of NLP research has seen a shift from older Neural Networks to Google’s Transformer architecture, enhancing training efficiency. With traditional Recurrent and Convoluted Neural Networks, information had to be processed step by step, whereas Transformers process entire strings simultaneously. The efficiency of Transformers allows larger models to be trained on more data.

The effort continues

Efforts to decipher animal communication have explored various species, including cetaceans, birds, and monkeys. Paridae, a family of birds like chickadees and tits, showcase a particularly complex vocal system. Their calls consist of distinct notes in an open-ended vocal structure, a rarity in non-human communication systems. These complex vocalizations serve various purposes due to their social complexity.

Efforts to translate animal communication into human language are ongoing, with potential applications in conservation and understanding animal behavior. Improved understanding of animal communication could aid conservation efforts by providing insights into stress levels, behavior changes, and environmental impacts. For instance, recognizing changes in bird species interactions due to climate change can help address challenges to survival.

While direct communication with animals may remain elusive, decoding their communication offers valuable insights into their world and contributes to conservation and welfare efforts. AI and technology play crucial roles in deciphering the intricate languages of our animal neighbors.
