If you're tasked with reporting on this file, here are some steps you could consider:
| Component | What it does | Why it matters | |-----------|--------------|----------------| | Audio‑Preprocessor | Normalises volume, removes background hum, and splits the audio into 30‑second chunks | Improves ASR accuracy; reduces memory spikes on long files | | ASR Engine (DeepSpeech‑2 + custom acoustic model) | Turns each chunk into raw text with timestamps | Handles domain‑specific vocab (e.g., medical, legal) that generic engines miss | | Speaker‑Diarisation | Labels “Speaker 1”, “Speaker 2”, … using a lightweight clustering algorithm | Makes the final captions readable—viewers know who’s talking | | Punctuation & Capitalisation | Applies a BERT‑based post‑processor to add commas, periods, question marks | Raw transcripts are a wall of lowercase; punctuation restores natural rhythm | | Timing Optimiser | Aligns each line to the nearest key‑frame (≤ 0.2 s error) and merges short fragments | Prevents jittery captions that flash too quickly | | Quality‑Gate (Human‑in‑the‑Loop) | Flags low‑confidence segments (> 0.75 confidence) for optional human review | Guarantees 98 %+ accuracy for mission‑critical content | Content Overview :
All of this happens in ≈ 30 minutes for a 2 h 23 min video on a modest 8‑core workstation—hence the “convert02‑23‑30 Min” moniker.
