South Korea’s SmileStory Releases
‘Global Sign Language Unification System’ for Free
World’s First ISP (International Sign Phonology) Established — “70% of Deaf People Live Without Language”
🤟 WIA Talk — Unifying Sign Languages Worldwide
Executive Summary
SmileStory Inc. (CEO: Yeon Sam-Heum), following its December 9th release of the world’s first ‘7,000-Language Braille System (WIA Braille)’, has now announced WIA Talk — a system unifying 353 sign languages worldwide — along with ‘ISP (International Sign Phonology)’, the IPA equivalent for sign languages. Both will be released patent-free and completely free to the global community.
Currently, 353 distinct sign languages exist worldwide, but cross-border communication remains nearly impossible due to incompatible systems. The more alarming reality: 70% of deaf children grow up without acquiring proper language skills.
The Shocking Reality: “7 Out of 10 Deaf Children Have No Language”
Most people assume “deaf people use sign language.” Wrong.
90-95% of deaf children are born to hearing parents. The problem is that most hearing parents don’t know sign language.
When 100 deaf children are born:
- ├── 5-10: Deaf parents → Natural sign language acquisition ✓
- └── 90-95: Hearing parents
- ├── ~30: Somehow acquire language
- └── ~70: Language deprivation ← CRISIS
Yeon Sam-Heum, CEO:
“When we meet someone who ‘knows sign language,’ we take it for granted. But that person is already among the lucky 30%. The remaining 70% live their entire lives without even the basic tool for thinking.“
The “Golden Window” of Human Language Acquisition
- Age 0-5: Perfect acquisition possible (Golden Window)
- Age 6-12: Possible but incomplete
- Age 13+: Basic communication only, abstract thinking impaired
Language is not just a “communication tool.” Language is the “tool for thinking.”
A child who doesn’t acquire language by age 5 will struggle with complete language abilities for life. This isn’t unique to deaf individuals — it’s a fundamental principle of cognitive development.
Medical Technology Advances — And the Remaining Challenge
Cochlear implants represent a remarkable achievement in auditory medicine. Many deaf children can now experience the world of sound thanks to this technology.
Cochlear Implant Achievements:
- Early surgery significantly aids spoken language development
- Effects maximized when combined with auditory rehabilitation
- Many children can attend mainstream schools
However, recent research in linguistics and audiology increasingly emphasizes the importance of “Bimodal-Bilingual” approaches.
According to the American Academy of Pediatrics (AAP) and related research:
- Cochlear implants provide “hearing assistance,” not “perfect hearing”
- Learning both spoken and sign language creates synergistic effects
- The key during ages 0-5 is language exposure in any form
The problem is that many families, due to lack of information, are forced into a false “spoken OR sign” dichotomy. In reality, “spoken AND sign” may be far more effective.
Real-world challenges:
- ├── Hearing parents: Don’t know where to learn sign language
- ├── Schools for the Deaf: Only 13 in South Korea (low accessibility)
- ├── Sign language education: Lack of systematic programs
- └── Result: Lost language exposure during the 0-5 golden window
Yeon Sam-Heum, CEO:
“Medical technology continues to advance. But there are aspects technology alone cannot solve. If parents don’t know sign language, no device can enable real ‘conversation’ with their child. WIA Talk aims to bridge that gap.”
Developing World Reality: “Endless Darkness”
–>
Deaf people worldwide: 70 million
80% of them: Living in developing countries (~56 million)
| Country |
Situation |
Result |
| South Korea |
13 deaf schools, free tuition, insurance coverage |
Still accessibility issues |
Ethiopia
(Pop. 120M) |
3 deaf schools, ~1 million deaf people |
99% have no educational access |
DR Congo
(GDP/capita $580) |
Almost no deaf schools; Cochlear implant $30,000 = 50 years’ salary |
Hundreds of thousands survive without language |
Over 50 million deaf people are likely living “without language.”
From WIA Braille to WIA Talk: Same Philosophy, Different Senses
WIA Braille, released on December 9th, unified braille for 7,000 languages based on IPA (International Phonetic Alphabet).
WIA Talk applies the same philosophy to sign language.
WIA Braille: Text → IPA → Braille
(214 languages → 1 unified braille system)
WIA Talk: Gesture → ISP → Sign
(353 sign languages → 1 unified sign system)
ISP (International Sign Phonology): The IPA of Sign Languages
1888 — IPA (International Phonetic Alphabet) was born. All human “sounds” could now be transcribed in one unified system.
December 13, 2025 — In South Korea, ISP (International Sign Phonology) was established. All human “gestures” can now be transcribed in one unified system.

The 5 Components of ISP
–>
| Code |
Component |
Description |
| HS |
Handshape |
Shape of the hand (fist, open palm, index finger, etc.) |
| LC |
Location |
Position relative to body (face, chest, neutral space, etc.) |
| MV |
Movement |
Motion path (up-down, circular, linear, etc.) |
| OR |
Orientation |
Palm direction (up/down, toward/away from body, etc.) |
| NM |
Non-manual |
Non-hand signals (facial expression, mouth shape, head movement, etc.) |
Example:
HS01-LC07-MV10-OR02-NM15 = A specific sign word
Same code = Same meaning = Communication possible anywhere in the world
A Barrier No One Crossed for 137 Years — Broken Again
IPA was created in 1888, yet for 137 years, no one applied it to braille. WIA Braille discovered that missing link.
Similar attempts existed in sign language:
| System |
Year |
Limitation |
| Stokoe Notation |
1960 |
ASL-only, not universal |
| HamNoSys |
1989 |
Too complex, academic use only |
| SignWriting |
1974 |
Visual notation, standardization failed |
Why WIA Talk is Different:
- MediaPipe/AI-based real-time hand tracking (2025 technology)
- Practical motivation (global communication)
- Bottom-up approach (353 sign language data collected)
- “Connection” not “replacement” strategy
“We Won’t Tell Anyone to Switch”
Yeon Sam-Heum, CEO:
“I will never tell anyone to ‘switch to WIA Talk.’ I know why Esperanto failed. Force doesn’t work.“
“But if you learn one more… learn it like you would learn a foreign sign language… you gain a channel to communicate with deaf people worldwide. A global communication channel.”
“If it’s convenient and good, people will naturally use it. Just like English did. Generations will pass, and they will naturally become one. Not because I told them to switch.“
The 100-Year Scenario
–>
| Year |
Status |
| 2025 |
7,000 spoken languages → each with different braille
353 sign languages → each with different systems |
| 2125 |
7,000 spoken languages → 1 IPA-based braille (WIA Braille)
353 sign languages → 1 ISP-based sign (WIA Talk) |
The “language unification” that the non-disabled failed to achieve for millennia,
may be achieved by the disabled in just 100 years
