Why transcribing long meetings matters
A two-hour strategy session or a four-hour workshop produces a large volume of decisions, commitments, and context. Relying on handwritten notes or memory means losing most of it. A verbatim transcript gives every participant a shared, searchable record of what was said and by whom.
Transcripts also make meetings accessible to colleagues in different time zones, people who could not attend, and team members who need to review a specific segment without watching a full recording. Vook works from the recording you already have: record the meeting with your own tool, then upload the file.
How Vook handles multi-hour audio files
Vook returns a transcript in under one minute per hour of audio, so even a long recording is ready in a few minutes. The key specs to know before uploading:
- File size limit. Up to 5 GB per file, or 10 GB on the Unlimited plan.
- Duration limit. Up to 5 hours per file, with no duration limit on the Unlimited plan. The free tier covers up to 30 minutes per file.
- Supported formats. 20 audio and video formats, including MP3, WAV, M4A, FLAC, OGG, AAC, OPUS, MP4, MOV, WEBM, WMA and MKV.
For very long recordings (full-day conferences, multi-session workshops), the Unlimited plan lifts the per-file duration cap and raises the file size limit to 10 GB.
Speaker diarization in long meetings
Diarization is the process of separating a recording into segments by speaker. In a meeting with five participants talking for three hours, diarization means the transcript shows "Speaker 1," "Speaker 2," etc. at every turn, rather than a single undifferentiated block of text.
Vook applies automatic diarization to every transcript. After processing, you can rename each speaker label (e.g., "Speaker 1" to "Anna"), create a speaker, or reassign a passage to the right speaker if the AI attributed it to the wrong voice. Timestamps are added at every speaker turn, so finding a specific moment in a long recording takes seconds.
Accuracy: what affects it and how to fix errors
Vook reaches up to 99% accuracy on clear audio in supported languages. For multi-hour meetings, several factors influence the result:
- Microphone quality. Recordings made with a dedicated microphone or a conferencing system outperform phone audio or built-in laptop mics.
- Overlapping speech. When two people speak at the same time, accuracy drops for both segments.
- Strong accents or technical jargon. Domain-specific terminology may need a quick review.
- Background noise. Open-plan offices or rooms with echo affect clarity.
Vook's built-in editor lets you correct errors directly in the transcript, fix speaker attribution, and re-export without reprocessing the file. Timestamps make it quick to jump to the passages that need a second listen.
Summarizing a long meeting transcript with Vook Chat
Reading a 40-page transcript of a three-hour meeting is not practical. Vook Chat lets you work with your transcript directly: ask for meeting notes or a summary, request a list of action items, extract all decisions made, or identify the main topics discussed. The output is grounded in your actual transcript, not a generic summary.
Typical Vook Chat use cases for long meetings include generating a one-page executive summary, pulling all commitments made by each speaker, and listing open questions raised during the session. The free tier includes a daily number of Chat messages; unlimited Chat is included in every subscription.
Privacy and compliance for meeting recordings
Meeting recordings often contain confidential business information, personal data, or legally sensitive content. Before using any transcription service, it is worth checking where your data goes and how it is handled. Vook's approach:
- Stored in France. Your audio files and transcripts are stored in France (EU).
- AES-256 encryption. Data is encrypted at rest.
- No AI training. Your recordings are never used to improve models, never resold, never analyzed for ads.
- You decide when files disappear. Recordings stay in your account until you delete them; deleting a transcript removes its audio, and deleting your account removes everything.
- GDPR-native. DPA available on request, no advertising profiling.
For organizations subject to GDPR, NDA obligations, or internal data governance policies, Vook.ai is a French company, GDPR-native, with a DPA available on request. EU data residency for AI processing is available on request.
