Language Contact in the American Deaf Community

The short answer

Language contact in the American Deaf community describes what happens when American Sign Language (ASL) and English, along with other languages, meet in the daily lives of deaf and hearing signers. Because most deaf Americans live, study and work alongside written and spoken English, the two languages constantly influence each other. The results include fingerspelling, signs borrowed from English spelling, mouthing of English words, a blended variety usually called contact signing, and, among bilinguals who can hear, signing and speaking at the same time. These outcomes are natural products of bilingualism. They are different from ASL itself and from invented systems designed to represent English on the hands.

One limit applies to this guide: no specific studies, figures or measurements were supplied for it. What follows draws on widely documented principles of sign language sociolinguistics rather than new data. Where a point is an inference, it is labeled as one.

Why ASL and English are in constant contact

ASL is a full natural language with its own grammar. Its grammar uses space, movement, handshape and facial expression, and it is not derived from English. Most deaf children, however, are born to hearing parents, are educated in settings where English dominates, and read and write English throughout their lives. Many deaf adults are therefore bilingual in ASL and English to varying degrees. Hearing people who sign, such as interpreters, teachers, family members and children of deaf adults (often called CODAs), bring English into signed interactions as well. This steady overlap is the setting for language contact.

ASL also has contact history with other sign languages. Its development is historically linked to French Sign Language, brought to the United States through early deaf education in the nineteenth century. Today American signers also meet signers of other national sign languages and use International Sign, a flexible contact variety, at international gatherings.

Common outcomes of ASL–English contact

• Fingerspelling: spelling English words letter by letter with the manual alphabet. It is often used for names, places, technical terms and words without an established sign.
• Lexicalized fingerspelling: frequently fingerspelled words that have become compressed into sign-like units. Over time they behave more like signs than like spelled words.
• Initialized signs: signs whose handshape is the manual letter for the first letter of an English word, which links the sign to its English equivalent.
• Mouthing: silently forming English words on the lips while signing. This is distinct from the mouth movements that belong to ASL grammar itself.
• Code-switching: moving from one language to the other within a conversation, for example from ASL into fingerspelled or written English.
• Code-blending: producing signs and spoken words at the same time. This is most associated with hearing bilinguals such as CODAs, because it requires access to speech.
• Contact signing: a blended variety that combines ASL vocabulary with features of English structure and frequent mouthing.

Contact signing and how it differs from other varieties

Contact signing was once widely called Pidgin Sign English. Sociolinguists Ceil Lucas and Clayton Valli, whose early-1990s work shares this article's title, argued that the pidgin label does not fit well. Classic pidgins arise when groups without a shared language need to communicate. Contact signing, by contrast, is often used by people who share both ASL and English. It typically draws its vocabulary mainly from ASL, follows English word order to a greater degree, uses less of ASL's spatial and facial grammar, and includes a good deal of English mouthing. Its exact makeup varies from one signer and situation to the next.

• ASL: a natural language with its own grammar, independent of English.
• Contact signing: a natural, variable blend that emerges when ASL and English users interact.
• Manually coded English systems, such as Signing Exact English: deliberately invented codes that represent English grammar and word endings on the hands, mainly for educational purposes. They are not natural products of contact.
• International Sign: a flexible contact variety used between signers of different national sign languages. It is not a standardized national language.

What shapes which variety people use

Research on this topic has consistently found that social context drives language choice more than individual ability does. Signers may shift toward contact signing when they are unsure whether the person they are talking to is deaf or hearing, when the setting is formal or unfamiliar, or when the conversation involves English-heavy topics. They may shift toward ASL in relaxed settings with other deaf signers. A fluent ASL user who produces contact signing in a given conversation is usually adapting to the situation, not showing a gap in skill.

Practical implications for webcam video and audio capture

For signed conversations on video calls, the camera matters far more than the microphone. Signing is visual, and several contact features depend on visual detail. Mouthing and ASL facial grammar require a clearly lit, visible face. Fingerspelling involves quick, small hand movements. It is a reasonable inference, not a measured finding, that low frame rates, heavy compression or poor lighting make fingerspelling and mouthing harder to read than larger, slower signs. Framing that keeps the hands, face and upper body in view supports all of these features.

Audio still matters in some situations:

• Code-blending: when a bilingual signer speaks while signing, a microphone captures the spoken channel for hearing participants.
• Interpreted calls: when an interpreter voices for a deaf signer, or signs for a hearing speaker, the quality of the spoken audio affects the interpretation.
• Mixed groups: when hearing participants who do not sign join a meeting, clear speech capture becomes necessary.

A built-in webcam microphone may be adequate for a single speaker seated close to the camera in a quiet room. In noisier rooms, or for interpreters who need consistent voice clarity, a dedicated microphone positioned nearer the speaker is generally preferable. No performance data for specific webcam microphones was supplied, so no model recommendations can be made here.

One further point is worth checking. Many conferencing platforms choose the main video view based on who is producing sound. A deaf participant who is signing silently may therefore not be automatically spotlighted. Pinning or spotlighting the signer's or interpreter's video, where the platform allows it, works around this. Platform features vary, so confirm what your software supports.

Gaps in the available evidence

The material supplied for this guide contained no specific figures, study results, dates or technical specifications. As a result, this article does not quantify how common each contact feature is, compare regional or ethnic varieties such as Black ASL, or offer tested video and audio settings for signed calls. Readers who need those details should consult current sociolinguistic research and accessibility documentation from their conferencing provider.
