Layer 4 — Inclusive Access

Voice + Haptic + Simplified

Multi-modality access with continuous fairness audit — every cohort counts, every cohort tracked.

Sesim Inclusive Access (Layer 4) reaches every voice — visual, hearing, motor, cognitive and elderly cohorts — with continuous bias detection (Patent claim 53) across accent, age, gender and language-switch deltas; production halts for any cohort that breaks the threshold. Multi-jurisdiction compliance built-in: KVKK m.6 + GDPR Art. 9 + EU Accessibility Act 2019/882 + EN 301 549 + ADA Title II/III + AODA + BDDK §11 — one SDK. Combined with Layer 1 (coercion detection) and Layer 2 (voice identity), one voice intent yields four signals: who + under coercion? + what action + accessibility need.

Public-sector pilot

Live Layer 4 deployments require a partner-led pilot with a public agency, NGO, or regulated bank. To request access for an e-government, kiosk, ATM, healthcare MIS, or accessibility audit pilot, contact us.

Demo flow (illustrative)

A typical 4-modality access turn — illustrated only. No real audio is captured on this page; live access requires a partner-led pilot.

How 4-modality access works

Voice guidance: TTS responses adapt to user speed (slow / normal / fast) and persona (male / female / neutral).
Haptic confirmation: short / long / pattern vibrations replace audio cues for hearing-impaired users.
Simplified-command vocabulary: short verb + noun structure; every action mapped to a clear word (Patent claim 16).
Multi-language code-switching: TR/EN in a single utterance handled by language-segment ASR (Patent claim 49).
Bias detection (Patent claim 53): accent / age / gender / language-switch deltas continuously monitored. >25% delta = production halts for that cohort.
WCAG 2.2 AA SDK conformance: 47 success criteria automatic, 18 partner-environment guidance.

Why public-grade not consumer-grade

Consumer accessibility tools (NVDA, JAWS, VoiceOver) are screen readers — one-way (screen → speech). Sesim L4 is two-way (speech ↔ speech + haptic).
No commercial competitor offers integrated bias-detection guardrail with public reporting.
EU Accessibility Act (2019/882), EN 301 549, ADA Title II/III, AODA, BDDK §11 — all aligned in one SDK.
KVKK m.6 / GDPR Art. 9 explicit-consent flow built in: disability status = sensitive data, 7-year audit retention.
Patent moat (Türkpatent claims 16, 25, 27, 49, 53, 109) — category-protective IP for "Accessibility-as-a-Service".
Cross-layer with L1: elderly coercion detection (Patent claim 47 silent-alarm) — protects vulnerable users from family / caregiver pressure.
