Language identity and boundaries Establishes what counts as Czech Sign Language and how external naming systems refer to it.
Names and identifiers
Records attested names and authority-specific identifiers without equating them with the language itself.
Attributed language designations
Require evidence for each Czech or international name and each catalogue designation.

What it is Filled
Czech Sign Language is a natural visual-gestural language used by Deaf communities in Czechia, with its own grammar distinct from spoken Czech.
In scope
- Language identity, names, identifiers, and boundaries with signed representations of Czech and neighbouring sign languages
- Manual, nonmanual, spatial, and discourse features needed to recognise and describe Czech Sign Language
- Regional, generational, social, and situational variation among users
- Dated evidence about user populations, language acquisition, and intergenerational transmission
- Status and actual provision in education, public services, and interpreting
- Language documentation, annotation, and resource suitability
Out of scope
- Spoken and written Czech as a separate language
- Signed Czech and other manually coded representations of spoken languages as independent systems
- Slovak Sign Language and other neighbouring sign languages
- Hearing diagnoses, audiological treatment, and individual medical records
- Deaf organisations, schools, and interpreting providers as institutional entities
- Video platforms, recognition software, and notation systems as technical products
Why it exists Filled
Enable an AI agent to recognise Czech Sign Language, assess evidence about its use and accessibility, and choose language resources or support appropriate to a particular signing community and task.
Distinguishing features Filled
- Identify Czech Sign Language through linguistic evidence and community attribution; a Czech location or Czech citizenship does not establish the language being used.
- Distinguish Czech Sign Language from signed Czech by examining grammatical organisation, including nonmanual and spatial patterns, rather than merely recognising individual signs.
- Do not classify a sample as Czech Sign Language solely because it contains fingerspelled Czech words or Czech subtitles.
- Keep Czech Sign Language distinct from Slovak Sign Language unless evidence supports a narrower claim about contact, shared forms, or a particular user's repertoire.
- Treat Czech gloss labels, dictionary entries, and language codes as representations or identifiers, not as complete evidence of natural signing.
What robots and AI may and may not do Filled
Must not
- Confuse it with signed Czech, the system that follows spoken Czech word order.
- Interpret for Deaf people in courts, hospitals or official matters.
- Publish videos of signers without their consent.
Only with a human decision
- Choosing an automated tool instead of an interpreter for a Deaf person's service.
May
- Describe Czech Sign Language, its grammar and status from reliable sources.
- Point people to qualified interpreters and Deaf organizations in Czechia.
Moral aspects Filled
- Deaf people have a right to communicate in their own language.
- Signers are visible in every recording, so publishing them always identifies them.
Who is affected
- Deaf people in Czechia
- Interpreters
- Deaf children and their families
Owners Filled
Steward
The Deaf community that uses it; Czech law recognizes it as a language of the Deaf.

Recognition optional Filled
- Communication combines manual signs with facial expression, gaze and spatial organization, although these features are shared with other sign languages.
- Natural signing uses its own grammatical organization rather than simply reproducing spoken Czech word order.
- Reliable identification requires recognizable vocabulary and grammatical patterns assessed by someone familiar with the language.
Capabilities and actions required Filled
- Assess whether a labelled resource actually documents Czech Sign Language and record uncertainty when evidence is insufficient.
- Select vocabulary and learning resources appropriate to a user's community, register, and task.
- Compare dated population and transmission evidence without merging incompatible definitions of users.
- Identify documented language-support requirements and verify practical provision for a particular setting.
- Assess whether recordings and annotations support a proposed linguistic or computational use.
- Route ambiguous or consequential language decisions to qualified Czech Sign Language users, researchers, or interpreters.
Hazards and failure modes required Filled
- Confusing the language with manually coded Czech can produce inaccurate interpretation and inaccessible services.
- Assuming that sign languages are universal can lead to selection of unsuitable interpreters or resources.
- Obstructed views or poor video framing can remove essential hand, facial and spatial information.
- Unverified automated interpretation can distort meaning in consequential interactions.
Standards and interfaces required Filled
- ISO 639-3, issued by the International Organization for Standardization, identifies Czech Sign Language with the language code cse.
- Act No. 155/1998 Coll. on the communication systems of deaf and deafblind persons, adopted by the Parliament of the Czech Republic and subsequently amended, provides a legal framework for its use.
Context of use required Filled
- Czech Sign Language is used for everyday communication, education and cultural participation within Deaf communities in Czechia.
- It is also used in interpreting and accessible public services where users require communication in their own language.
