The Importance of Studying Phonetics and Phonology in Sign Languages: An Exploration of Linguistic Universality

Despite the accusation of redundancy, linguists continue to delve into the phonetics and phonology of sign languages. This practice not only highlights the intrinsic structure and complexity of sign languages but also facilitates a deeper understanding of linguistic theory as a whole. In this article, we will explore the reasons behind this approach, the parameters involved, and the interdisciplinary value it brings to the field.

Understanding Phonetic and Phonoanalogues in Sign Languages

When linguists study sign languages, they utilize the terms 'phonetics' and 'phonology' to examine the visual-manual modality of sign systems. These terms serve to parallel the auditory-vocal modality of spoken languages, ensuring a comprehensive analysis of sign languages as legitimate linguistic systems.

What are Phonetics and Phonology?

Phonetics focuses on the physical properties of sounds or signs in sign languages. This includes detailed examinations of parameters such as handshape, location, movement, palm orientation, and facial expressions. By understanding how these parameters are produced and perceived, linguists can better grasp the mechanics of sign language production.

Phonology delves into the abstract cognitive aspects of sign language systems. This involves studying how signs function within a language and the rules that govern their combination and use. Just as phonology in spoken languages analyzes the structure of sounds, phonology in sign languages explores the structure of signs and their role in communication.

Parameters of Sign Languages

Sign languages have distinct parameters that function similarly to phonemes in spoken languages. These parameters include:

Handshape: The configuration of the hands. This parameter is crucial for conveying specific meanings and can vary widely across different signs. Location: The place in the signing space where the sign is made. Different locations can significantly alter the meaning of a sign, much like different placements of sounds in spoken languages. Movement: The motion of the hands and arms. Movement patterns are essential in sign languages, as they contribute to the dynamic nature of the sign. Palm Orientation: The direction the palm faces. This parameter can provide additional nuances to the meaning of a sign, similar to how the position of a lip or tongue alters the meaning of a spoken word. Facial Expressions: Non-manual markers that convey grammatical information. These expressions play a vital role in the visual aspect of sign languages, supplementing the manual aspects with important linguistic cues.

Analogies to Spoken Languages

The use of 'phonetics' and 'phonology' helps to establish analogies between spoken and signed languages. This analogy is essential for linguists to develop a more comprehensive understanding of linguistic theory. It emphasizes that sign languages, like spoken languages, are fully developed with their own unique linguistic structures. By drawing parallels, linguists can enhance their research and provide a more nuanced view of the human capacity for language.

While some may argue that sign languages do not require the same terminology as spoken languages, the use of these terms highlights the complexity and richness of sign languages. It also underscores the fact that sign languages are not merely a visual representation of spoken words but have their own intricate system of sound-like elements.

Why Not Use Specialized Terms?

The question of why linguists do not use specialized terms to describe the unique aspects of sign languages is valid. However, the use of familiar terms from spoken language studies allows linguists to build upon existing research and theories. This interdisciplinary approach enables a more integrated understanding of both spoken and signed languages, fostering collaboration and innovation.

By maintaining consistency with terms used in spoken language studies, linguists can draw on a wealth of research and theoretical frameworks. This approach not only ensures that the study of sign languages is grounded in a robust theoretical foundation but also facilitates the translation of insights across different language modalities.

Interdisciplinary Collaboration

The use of phonetics and phonology in the study of sign languages not only reflects the complexity of the language but also highlights the interdisciplinary nature of linguistic research. By integrating knowledge from various fields, linguists can gain a more comprehensive understanding of language as a whole. This collaboration can lead to innovative research methods and a more holistic approach to linguistics.

Interdisciplinary research can also inspire new questions and areas of investigation. For example, the study of sign language phonetics and phonology can reveal insights into the cognitive processes involved in language production and perception. This, in turn, can inform research in other disciplines such as cognitive science and neurolinguistics.

Conclusion

In conclusion, the use of phonetics and phonology in the study of sign languages is not only a matter of convention but also a reflection of the complex and rich nature of sign languages as legitimate linguistic systems. While some may argue against the use of familiar terms, the interdisciplinary approach and the need for a robust theoretical foundation make this practice essential for advancing our understanding of language and communication.
