PROJECT / MINUTES

The meeting goes in as audio and comes out as minutes.

An application that runs on your own machine: it transcribes the recording of an in-person meeting, tells the speakers apart and drafts the minutes with an agenda, numbered resolutions and a task table. Downloads as Word or PDF.

It works and gets occasional use. Not offered as a finished product yet.

From audio to document

Five steps, nearly all on your own machine.

The only thing that leaves the machine is the already-compressed audio, and it is deleted from the server as soon as transcription finishes. Minutes, transcript and metadata stay local.

  1. 01

    Normalise

    ffmpeg converts any input format to 16 kHz mono MP3. That is why it does not matter whether you recorded on a phone or a dictaphone.

  2. 02

    Split

    Anything over 25 minutes is cut into 20-minute blocks with 15 seconds of overlap, so no sentence gets sliced in half.

  3. 03

    Transcribe

    Each block is transcribed asking for structured output: speaker, start, end and text. When it finishes, the audio is deleted from the server.

  4. 04

    Merge

    Timestamps are shifted back into place, whatever repeats inside the overlap is dropped and speaker labels are unified across blocks.

  5. 05

    Draft

    A second pass, text only, writes the minutes from the transcript and the form details.

Long meetings

Two hours of meeting is not two hours of upload.

The conversion to mono MP3 happens before anything is sent, so the size of the original barely matters. Measured on a real two-hour recording:

Two-hour sourceSize
Phone voice memo60 MB
Meeting recorder115 MB
Uncompressed WAV1.2 GB
What the app uploads41 MB

Local preparation of those two hours takes about a minute.

An ALUNA project

It came out of a specific need.

It was built to write up minutes of real meetings without losing an afternoon to it. If your team has the same problem, it can be adapted to your template and the way you work.
