Multilingual Communication Preferences & Translation Layer - Senior PHP / CodeIgniter Developer

HOTELHUB / OPERATIONSHUB Language Preferences & Translation Orchestration Layer v1.0 (Multilingual Communication Preference Infrastructure) Built Against: • Push-to-Talk Unified Master Scope v2.3 • Operational Accessibility Addendum v1.0 • Real-Time Translation Layer Scope v1.0 • Existing Translation Provider Abstraction Infrastructure Purpose This scope introduces centralized multilingual communication preference management for operational communication systems. This layer exists to: • personalize multilingual communication behavior • reduce communication friction • improve translation usability • support multilingual frontline operations • standardize translation behavior across communication systems This scope is configuration and orchestration focused. This scope does NOT introduce: • conversational AI • autonomous AI systems • employee monitoring • sentiment analysis • workflow automation PART I — USER LANGUAGE PREFERENCES 1.1 User Preferred Language System must support: • primary/preferred language selection per user Examples: • English • Spanish • Haitian Creole • Portuguese • French • Arabic • Chinese (Simplified) Language availability must remain configurable by hotel/system settings. 1.2 Secondary Language (Optional) System may support: • secondary/preferred fallback language Example: • primary = Spanish • secondary = English 1.3 Translation Preference Settings Users may configure: • auto-translate incoming communication • show original language first • show translated language first • narration playback preferred language • live captions enabled/disabled • translated narration enabled/disabled PART II — HOTEL LANGUAGE CONFIGURATION 2.1 Allowed Language Packs Hotels may define: • supported operational languages • enabled translation languages • narration-capable languages 2.2 Hotel Default Language System must support: • hotel-level default operational language 2.3 Future Expansion Reservation Architecture must remain compatible with: • regional language packs • department-specific language preferences • portfolio-wide language governance PART III — COMMUNICATION ORCHESTRATION 3.1 Incoming Communication Behavior System must support: • automatic translation of incoming operational communication • optional manual translation trigger • translation preference persistence 3.2 Outgoing Communication Behavior System may support: • preferred outgoing translation handling • automatic recipient-language translation routing 3.3 Translation Visibility Users must always be able to: • view original communication • view translated communication • identify source language • identify translated language Original operational communication remains source-of-truth. PART IV — LIVE TRANSLATION SETTINGS 4.1 Real-Time Translation Preferences Users may configure: • live captions enabled/disabled • translated captions enabled/disabled • preferred live caption language 4.2 Narration Preferences Users may configure: • translated narration playback enabled/disabled • narration playback language preference Narration must remain: • user-triggered • non-intrusive • operationally lightweight PART V — ARCHITECTURAL REQUIREMENTS 5.1 Provider Abstraction Compliance System MUST: • remain provider-agnostic • avoid provider-specific UI coupling • avoid hardcoded provider assumptions 5.2 Shared Infrastructure Consumption This layer MUST consume: • existing translation infrastructure • existing narration infrastructure • existing provider abstraction architecture No parallel translation infrastructure permitted. 5.3 Mobile Compatibility All preference management MUST remain compatible with: • handheld execution • tablet execution • Thin Native Container architecture PART VI — SECURITY & ISOLATION 6.1 Tenant Isolation All language preferences MUST remain: • hotel-isolated • permission-aware • role-safe 6.2 Privacy Doctrine Language preferences exist solely to: • improve communication usability • improve translation quality • improve operational accessibility This data MUST NOT be used for: • employee scoring • profiling • behavioral analysis PART VII — ACCEPTANCE CRITERIA Acceptance requires: • user language preference persistence functional • translation preference persistence functional • multilingual communication rendering functional • original-language visibility functional • translation toggles functional • narration preference handling functional • mobile/tablet validation complete • no cross-tenant leakage • provider abstraction compliance verified STRATEGIC INTENT This layer exists to standardize multilingual operational communication behavior across HotelHub communication systems. This functionality is intended to improve operational communication clarity and accessibility — not replace human operational judgment or introduce conversational AI dependency.
