Meeting Transcription & Analysis

The average knowledge worker spends 31 hours per month in meetings. An estimated 50% of that is unproductive. AI transcription and analysis transform spoken words into searchable, analyzable, actionable data.

Whisper and Modern ASR Systems

OpenAI Whisper

Whisper has revolutionized the speech-to-text landscape:

  • Open source: Free to use, self-hostable
  • Multilingual: 99 languages, automatic language detection
  • Robustness: Works with background noise, accents, technical jargon
  • Model sizes: tiny (39M) to large-v3 (1.55B parameters)
  • Accuracy: Word Error Rate (WER) of 3–5% for German and English

Speaker Diarization

Who said what? Modern systems recognize individual speakers:

  • Unsupervised: Automatically detects different speakers ("Speaker 1", "Speaker 2")
  • Enrollment: Pre-registered voices → named attribution
  • Accuracy: 90–95% with 2–5 speakers, declining with more participants

Summaries and Action Items

AI-Generated Summaries

What good meeting summaries contain:

  • Key decisions: What decisions were made?
  • Action items: Who does what by when?
  • Discussion points: The key discussion points (not every detail)
  • Open questions: What remained unclear?
  • Next steps: What are the next steps?

Example AI Summary

*"Sprint Planning — 02/18/2026 Participants: Anna (PO), Ben (Dev), Clara (Dev), David (Scrum Master)

Decisions:

  • Feature X prioritized for Sprint 14 (effort: 8 SP)
  • Bug Y classified as critical, to be fixed immediately

Action Items:

  • Ben: API design for Feature X by Wednesday
  • Clara: Bug Y hotfix by tomorrow 12pm
  • Anna: Stakeholder update on Feature X timeline

Open Questions:

  • Performance impact of Feature X still needs evaluation"*

Analysis Over Time

AI can analyze meeting patterns:

  • Meeting efficiency: How much talk time vs. silence? How many action items per minute?
  • Dominance analysis: Who talks how much? (For leadership coaching)
  • Topic tracking: Which topics keep recurring and never get resolved?
  • Sentiment trend: Is team mood improving or declining?

Privacy Considerations

Clarify before introduction:

  • Consent: All participants must be informed that AI is recording
  • Recording: May the meeting be recorded? (Works council agreement!)
  • Storage: Where are transcripts stored? For how long?
  • Access: Who may see which transcripts?
  • Deletion: Define GDPR-compliant retention periods

Practical tip: Start with internal meetings (lower privacy hurdles) and expand to customer calls only after positive experience. And: Always announce at the beginning of the meeting that AI is recording.
