In this essay, it is described what animal communication can tell us about spoken language processing by mind and machine. First, it is explained how animal behaviour influences the human side. Then it is shown what can be learnt on the machine side. In conclusion, it can be said that the study of animal communication provides scientists with clues for creating theories of human speech evolution. However, more research in the future is necessary to underpin these theories. A number of questions still remain unsolved. The same is true on the machine side for the development of applications that copy animal techniques.

Excerpt from the Book
Ability to Speak and Understand
Humans can make particular sounds at will and suppress sound emissions whenever they want (Aitchison, 2001). They can also control their respiration, e.g. hold their breath at will for a short time. Most animals cannot do that but this is important for spoken language communication (Fitch, 2000). Only humans are able to produce the variety of different sounds that is needed to speak a human language. To create these sounds humans have a very mobile, L-shaped tongue that can not only move up and down but also backwards and forwards. Therefore, they can produce two formants and create the basic vowels [a], [i], and [u] that animals cannot (Aitchison, 2001).
The ability to produce language also involves syntactical matters. Word order is one point of interest in this area. Nim Chimpsky, a chimpanzee that learnt a sign language, sometimes used signs in random order but sometimes also had a preference for a particular word order (Aitchison, 2001). He often mentioned food items first in his utterances. For example, “banana Nim” meant that he wanted a banana. But he also repeated words, like in “give orange me give eat orange me eat orange give me eat orange give me you” (Aitchison, 2001:114). This behaviour is similar to the process that occurs when a new word order rule is added to a language. Structures that are often used become a rule in the language and combinations of structures form a new pattern and another new rule. In this way languages might have developed in the past. There are still changes in languages today, for example new words are added when new things are invented.
On the side of speech perception, one must look at the hearing abilities of humans and animals. Some animals can hear very well. The phenomenon of categorical perception can be found in humans, mammals, and birds (Hauser et al., 2002). This shows that this must have been developed before evolution divided mammals and birds and it was originally not created for speech.
Summary of Chapters
Introduction: Provides an overview of the challenges in understanding spoken language processing and outlines the comparative approach of studying animal communication to improve both biological theories and machine capabilities.
Spoken Language Processing by Mind: Investigates the evolutionary origins of speech, the anatomical differences between human and primate vocal tracts, the cognitive requirements for syntax, and the roles of imitation and mirror neurons.
Spoken Language Processing by Machine: Discusses the application of bionics and biomimicry in developing hearing aids, speech recognition algorithms, and robotic vocal systems based on natural observations.
Conclusion: Synthesizes the findings, emphasizing that while animal studies offer valuable clues for speech evolution and technological development, significant research gaps remain.

Frequently Asked Questions
What is the core focus of this publication?
The work examines how the study of animal communication provides fundamental insights into both the biological processes of human speech and the design of artificial speech processing machines.
What are the primary thematic areas covered?
Key areas include the evolution of human language, comparative anatomy of vocal structures, the psychological aspects of animal learning, and the implementation of biomimicry in modern technology.
What is the main objective of the research?
The objective is to establish links between animal behaviors and human communication, using these findings to refine theories of linguistic development and to improve technological speech interfaces.
Which scientific methods are employed?
The author uses a comparative research method, analyzing biological, anatomical, and psychological data from various species, as well as reviewing established studies on speech recognition and synthesis algorithms.
What topics are discussed in the main body?
The body covers speech evolution, the necessity of specific vocal tract anatomy, the cognitive ability of primates, the principles of mirror neurons, and practical applications in robotics and bionic medical devices.
Which keywords define this work?
Essential keywords include speech evolution, imitation, theory of mind, bionics, machine learning, and comparative anatomy.
How do apes demonstrate a 'theory of mind' in this study?
The study notes instances where bonobos like Kanzi demonstrate cognitive abilities comparable to human infants, such as understanding simple commands and engaging in pretend play, suggesting a rudimentary internal mental representation.
What role does the L-shaped tongue play in speech?
According to the text, the L-shaped tongue is critical for humans because it allows for the precise movement required to produce the specific formants and basic vowels necessary for complex human language, a capability not found in other animals.
