Voice Detection

Records ambient sound in restaurants and cafés, transcribes it and analyses service quality with AI. See what is said in your branches and what changes hour by hour.

One branch’s day: a separate recording for every opening hour. Bars show the ambient sound in that hour.

How it works

  1. Install with a setup code

    Download one file on the branch PC and enter a setup code. The microphone and settings are configured automatically; no technical skills needed.

  2. Record during opening hours

    Recording starts at opening and stops at closing. Sound is split by the hour and each part is uploaded with its branch and time.

  3. Transcribe and analyse

    Every hourly recording is transcribed and reviewed by AI: guest conversations, rush hours and the moments things go wrong.

What you see

  • Your branch, hour by hour

    Answer “what happens at 2 pm every day?” directly, and compare branches on the same hour.

  • Service quality

    Staff conversations with guests are transcribed; greetings, recommendations and complaints stand out.

  • Devices that go quiet

    Every recording’s level is measured. If a microphone is unplugged or deaf, the recording is flagged as silent.

Runs without anyone at the restaurant

After setup, nobody touches the branch PC again. Settings, hours and updates are managed remotely.

If the microphone is unplugged
the open recording is saved and recording resumes when it is back.
If the internet drops
recordings queue on the PC and upload when the connection returns.
If the power goes out
unsent recordings are found and uploaded on the next start.
When opening hours end
the partial hour is cut and uploaded too; nothing is lost.

Privacy

Audio recordings are personal data. Before installation, the business must inform its staff and guests about recording. Recording happens only during the defined opening hours, and every device can be stopped remotely with one command. The device password is stored encrypted on the PC, and a branch can only write its own recordings.
