I architected and developed high-performance, enterprise-grade Stenography and Typing examination engines currently powering industry-leading educational platforms, including StenoIQ.com, SpeedSteno.com (typing dedicated), and LearnSteno.in. Engineered to meet the rigorous standards of competitive government and shorthand examinations, these web tools process high-volume, real-time text analysis, providing thousands of students with precise, instantaneous performance evaluations.

Technical Breakdown & Core Features

·        End-to-End Stenography Pipeline: Implemented a seamless multi-stage workflow designed for authentic shorthand testing. The system handles automated audio dictation playback, allowing students to take notes traditionally on paper before transitioning to the portal's advanced transcription interface for digital entry and automated evaluation.

·        AI-Driven Error Classification: Integrated cutting-edge AI analysis layers to intelligently evaluate transcriptions. The engine mimics official examination board patterns, accurately differentiating between major errors (omissions, word substitutions) and minor errors (punctuation, spacing, formatting) to deliver deep, actionable insights.

·        Comprehensive Bilingual Support (English & Hindi): Engineered a robust, dual-language framework capable of processing complex multilingual text arrays. The typing engine dynamically adapts to both English and Hindi language structures seamlessly.

·        Advanced Hindi Font & Layout Architecture: Designed deep compatibility for Hindi layout complexities, natively supporting both Krutidev and Mangal (Inscript) typing standards.

·        Precision Keystroke & Alt-Code Mapping: Developed a specialized keystroke-level detection system capable of evaluating inputs across different font structures. It features full mapping for Krutidev typing with or without Alt codes, ensuring 100% accurate character validation and error logging even when users type complex, conjunct Hindi characters using legacy codes.

·        Real-Time Analytics & Performance Metrics: Built a high-speed analytics engine that instantly calculates core metrics, including Gross Words Per Minute (GWPM), Net Words Per Minute (NWPM), accuracy percentages, and backspace usage. The tool generates instant visual heatmaps, highlighting exact errors directly within the text layout for student review.

Impact and Scalability

Built using modern, scalable web technologies, this evaluation tool removes the logistical bottleneck of manual test grading for educational institutions. By delivering institutional-grade accuracy, processing complex font layouts seamlessly, and leveraging AI for deeper error diagnostics, this project stands as a benchmark for modern educational technology in the shorthand and typing domain.
