How AI Meeting Summaries Work: Technology Explained Simply
Demystifying AI meeting summarization: from speech recognition to NLP and GPT models. Learn what happens behind the scenes when AI takes notes.
Introduction
Ever wondered how AI magically transforms hour-long meetings into concise summaries? This article demystifies the technology behind AI meeting summarization.
The Technology Stack
1. Speech Recognition (ASR)
Converts audio into text using deep neural networks trained on thousands of hours of speech data.
2. Natural Language Processing (NLP)
Understands context, identifies speakers, and extracts meaning from the transcript.
| NLP Task | Technology | Accuracy |
|---|---|---|
| Speaker Identification | Deep Learning | 92-95% |
| Entity Recognition | Transformer Models | 88-93% |
| Sentiment Analysis | BERT/GPT | 85-90% |
| Topic Extraction | LDA + Neural | 80-87% |
3. Summarization Models
GPT-based models condense the transcript into key points, decisions, and action items.
How It Works Step-by-Step
1. Audio Capture: Meeting audio is recorded with high fidelity
2. Speech-to-Text: ASR converts speech to text in real-time
3. Speaker Diarization: AI identifies "who said what"
4. Context Analysis: NLP models understand topics and intent
5. Summary Generation: AI extracts key points and decisions
6. Action Item Extraction: Identifies tasks and assignees
The AI Pipeline Visualized
| Stage | Input | Output | Processing Time |
|---|---|---|---|
| Audio Capture | Meeting | Audio File | Real-time |
| Transcription | Audio | Text Transcript | ~15% of duration |
| Diarization | Transcript | Speaker Labels | ~5% of duration |
| Analysis | Labeled Text | Topics & Entities | ~10% of duration |
| Summarization | Analysis | Summary + Actions | ~20% of duration |
