Sahara v2.5 Winning Strategy: Unified Care Suite
AfriHealth AI connects all three challenge themes into a single End-to-End Care Continuum , satisfying 100% of judging criteria: voice task completion, rigorous 3-model benchmarking, and high-impact health execution.
1. Architectural Breakdown
Module 1: Triage
Captures audio from CHWs, removes noise, transcribes code-switching, and extracts ESI urgency levels.
Module 2: EHR Intake
Transcribes clinical consultation, extracts ICD-10 & vitals, auto-populating FHIR standard EHRs.
Module 3: Post-Care
Conducts autonomous voice check-ins, detects post-op complications, triggering nurse escalations.
2. Benchmarking Compliance
Compares Intron Sahara v2.5 against OpenAI Whisper and Gemini 3 Flash. Evaluates Word Error Rate (WER), Character Error Rate (CER), and Task Completion Reasoning (1-5 scale) tailored to Amharic-English code-switching.
3. Technical Governance & Privacy
Adheres to ISO 27001-aligned pipelines. All transcripts undergo automatic PII scrubbing prior to storage or EHR commit.
Close Strategy
