Manually Coded Language: Bridging Communication Barriers

In the diverse spectrum of human languages, manually coded languages (MCLs) occupy a unique niche. These languages, designed to represent spoken languages in a visual-manual form, serve as a vital communication bridge. They are particularly significant for the deaf and hard-of-hearing communities, providing a link between sign language and the spoken/written language of a broader population.

The Genesis and Evolution of Manually Coded Languages

Origins in Deaf Education

The history of manually coded languages is deeply intertwined with the evolution of deaf education. Initially, educators of the deaf sought ways to teach spoken language through visual means. This endeavor led to the development of various systems that represented spoken words and sentences using sign language elements or manual gestures.

Early Systems and Pioneers

One of the earliest forms of MCL was the “Manual Alphabet,” used for spelling out words. Notable figures like Charles-Michel de l’Épée in the 18th century contributed significantly to its development. These early systems laid the groundwork for more complex forms of manually coded languages.

Advancements and Variations

Over time, MCLs evolved, branching out into different systems. Each system varied in how closely it aligned with the grammar and syntax of the spoken language it represented. Some, like Signed Exact English (SEE), strove for a direct one-to-one correspondence with English. Others, like Conceptually Accurate Signed English (CASE), allowed for more flexibility, adapting sign language to approximate English grammar more naturally.

The Role of Manually Coded Languages in Deaf Education

A Tool for Literacy

In educational settings, MCLs have played a crucial role in teaching reading and writing skills to deaf and hard-of-hearing students. By providing a visual representation of spoken language, these systems help bridge the gap between sign language and written language.

Controversies and Debates

The use of MCLs in education has not been without controversy. Some advocates for deaf culture argue that focusing on MCLs can detract from the natural development and use of indigenous sign languages, which are linguistically complete and culturally significant.

Balancing Act: MCLs and Sign Language

Despite these debates, many educators strive to find a balance. They recognize the importance of native sign languages in preserving deaf culture while also acknowledging the practical benefits of MCLs in navigating a predominantly hearing world.

Manually Coded Languages in Everyday Communication

Bridging Gaps in Mixed Settings

MCLs find their application beyond educational settings, facilitating communication in mixed groups of deaf and hearing individuals. They allow for a more seamless interaction, especially in situations where interpreters or fluent sign language users are not available.

Accessibility and Inclusion

Inclusivity is a significant aspect of MCLs. By providing a means for the deaf and hard-of-hearing to access information and communicate in the spoken language of their community, these systems play an essential role in breaking down barriers.

The Future of Manually Coded Languages

Technological Advancements and Innovations

With the advent of technology, the role and form of manually coded languages are evolving. Digital platforms and software are being developed to translate spoken and written language into MCLs and vice versa, promising greater accessibility and ease of communication.

Challenges and Opportunities

As technology advances, the challenge remains to ensure that these innovations accurately and effectively represent the nuances of both spoken languages and sign languages. However, these advancements also open up new opportunities for improved communication and accessibility.

Preserving the Cultural Significance

While embracing technological progress, it is crucial to preserve the cultural and linguistic significance of manually coded languages and the sign languages they represent. This preservation is vital for maintaining the rich heritage and identity of the deaf community.


Manually coded languages serve as a vital tool in bridging communication gaps, offering both practical solutions and cultural significance. As we move forward, it is important to continue exploring and understanding these languages, ensuring they evolve in ways that honor their roots and enhance their potential to connect communities.

Understanding the Linguistic Structure of MCLs

The Interplay Between Sign Language and Spoken Language

Manually coded languages are not standalone linguistic systems but rather a blend of sign language elements and the structure of a spoken language. This interplay creates a unique linguistic phenomenon where gestures and signs are used to represent the phonology, syntax, and semantics of spoken words.

Sign Language Influence

The influence of sign language in MCLs is profound. Signs from native sign languages are often adapted or modified to fit the grammatical rules of the spoken language. This adaptation ensures that MCLs maintain a visual and spatial nature, leveraging the strengths of sign language communication.

Flexibility and Adaptation

Flexibility is a key feature of MCLs. Depending on the context and the communication needs, users may adjust the level of adherence to the spoken language structure. This flexibility allows for a range of expression, from a strict representation of spoken language to a more conceptually accurate form.

The Impact of MCLs on the Deaf Community

A Dual Identity

For many in the deaf community, manually coded languages offer a way to navigate between the world of deaf culture and the predominantly hearing society. This navigation often leads to a dual identity, embracing both the rich heritage of sign language and the practical necessities of interacting with the hearing world.

Community Perspectives

The reception of MCLs within the deaf community varies. Some view them as essential tools for integration and education, while others fear they may undermine the status and purity of native sign languages. This diversity of perspectives reflects the complex relationship between language, culture, and identity.

Advocacy and Empowerment

Advocacy for the use of MCLs often goes hand in hand with broader efforts to empower the deaf and hard-of-hearing. By promoting understanding and use of these languages, advocates aim to enhance access to education, employment, and social opportunities.

Challenges in Implementing Manually Coded Languages

Educational and Social Challenges

Implementing MCLs in educational and social settings presents several challenges. Ensuring that educators are adequately trained in these languages is crucial, as is the need for consistent and accurate use in the classroom. Socially, there is the challenge of raising awareness and acceptance among the hearing population.

Resource Allocation

The development of resources and materials in MCLs is another significant challenge. Creating textbooks, teaching aids, and digital content that effectively use MCLs requires time, expertise, and funding.

MCLs and Technology: A Synergistic Relationship

Digital Tools and Accessibility

Advancements in technology have opened new avenues for the use of MCLs. Digital tools and software that can translate spoken and written language into manually coded signs, and vice versa, are making communication more accessible and efficient.

Virtual Learning and Communication

The rise of virtual learning environments and online communication platforms offers unique opportunities for the integration of MCLs. These platforms can facilitate remote learning and interaction, breaking down geographical barriers and fostering inclusive communities.

The Role of Artificial Intelligence

Artificial intelligence (AI) and machine learning are playing an increasingly significant role in the development of MCL translation tools. AI algorithms can learn and adapt to the nuances of MCLs, potentially leading to more accurate and natural translations between spoken languages and sign languages.

Future Directions and Potential

Expanding Research and Understanding

Continued research and study into manually coded languages are essential. This research can deepen our understanding of the cognitive processes involved in MCLs, explore their impact on language development, and examine their role in the broader linguistic landscape.

Collaboration and Innovation

Collaboration between linguists, educators, technologists, and members of the deaf community is key to the future development of MCLs. Such collaborations can lead to innovative approaches and solutions, ensuring that MCLs continue to evolve in ways that are beneficial and respectful of the needs of the deaf and hard-of-hearing community.


Manually coded languages represent a fascinating and vital aspect of human communication. They illustrate the adaptability and creativity inherent in our linguistic abilities, serving as a bridge between different modes of expression. As we continue to explore and develop these languages, it is important to do so with a sense of responsibility and respect for the diverse communities they serve.

Manually Coded Language – Additional Commentary

One of the most important thing language does is connect people—when they speak the same language. This applies to those in the deaf culture, deaf people and the deaf community as much as it does to those that can hear. One of the ways that deaf people communicate is by using a “manually coded language,” such as the American Sign Language ASL. A manually coded language, typically created by those that can hear, involves the use of physical gestures to imply the grammar of a specific language, or the written word of that language, such as English, German, Spanish or more.

People from other countries that speak another language will use another form of a manually coded language to communicate with the hearing impaired. Each country may have its own manually coded sign language. Anthropologists and linguists believe the first languages were really sign languages and not spoken ones. Even babies learn to first speak with gestures before they begin to vocalize words.

In order for those who are deaf to learn to communicate, it requires a deaf education and the willingness to learn. When those who are born deaf are treated as a normal human being with a special need, then getting a deaf education will be easier for them. It starts with how the people in the homes of deaf people feel about deafness, deaf people, the deaf community and more. The first thing that is important for those that have someone in their lives that is deaf is to understand that deaf people have the same needs, desires and dreams as anyone else does. It takes a solid deaf education for the deaf person, the deaf person’s family members and friends to learn to communicate with each other. Learning a manually coded language that combines gestures to form words will help those who can hear communicate with those who cannot.

A manually coded language not only helps deaf people communicate with family members, it helps them communicate with other people with deafness, which can provide a sense of belonging to the deaf community. Everyone needs a place where they feel that they belong, and providing a deaf education for deaf people provides them a starting point that can provide a sense of deaf culture and belonging. Long ago, during medieval times, deaf people were considered somehow lower than a person who could hear. Some people mistakenly considered those with deafness as possessed, needing exorcism. It’s hard to believe that people could think that way, but they did. A Benedictine monk from England in the seventh century was the first to suggest a sign language based on Latin to communicate with the hearing impaired. Bede developed this system that helped people understand the hearing impaired.

Every human being alive has the right to communicate with others. In fact, it’s necessary to feel good about oneself to have this sense of belonging. Those in the deaf community understand this and are coming together to create their own deaf culture. If you know of someone that is hearing impaired, consider learning to speak his or her language, whatever that may be—you will not only make someone happier, but you might enjoy learning something new as well. Being deaf only means that deaf people can’t hear with their ears—it doesn’t mean they cannot communicate and hear in other ways.
