Analyze Student Engagement from 'WebVTT' Transcripts // Analyzes participation in course-session transcripts stored in the 'WebVTT' format https://www.w3.org/TR/webvtt1/, including transcripts exported by 'Zoom' and similar videoconferencing platforms. Provides tools to load and process transcripts, calculate speaker-level engagement metrics, create privacy- supporting plots and exports, and perform reviewable exact name matching against course rosters. Structured-field masking and technical privacy-review helpers support local review but do not determine legal or institutional compliance.
