Phase 2: Engineering a Dedicated Pipeline Agent
We engineered a pipeline that ingests raw video, using ffmpeg for audio extraction and Whisper for high-accuracy speech recognition. Built-in speaker diarization ensures we always know who is talking.
Rather than training a costly proprietary model from scratch, we layered strict system instructions over an LLM. We gave the AI the persona of a "Digital UX Researcher," ensuring it strictly analyzes data against the discussion guide.
The system generates structured Markdown reports from the transcripts, discussion guide and auto labelling sentiments to support efficient synthesis, and is fully architected to align with PDPA data handling principles.
