Sanako Sign Lab

Learn sign languages effectively with our easy to use tool. You can simultaneously play source video and record signing and/or speech – all you need is a PC with a camera.


Sanako Sign Lab can play the most common video and audio file formats. In addition, you can play back a file while recording your signing. You can open two files at the same time and play them simultaneously, and the playback of the two files can be easily synchronized. This way you can, for example, compare the two videos together in real time, to make self-assessments or to review student recordings.

  • Compare and combine videos easily
  • Simultaneously record your signing and source video
  • Practise sign language interpretation
  • PiP Picture-in-Picture recording
  • Possibility to stream live web camera across local network
  • Can be used outside the class for self-study

Picture in Picture Recording (PiP)

You can merge the source video and audio with your own recording by using Picture in Picture recording. This makes easy evaluation and self-assessment available without the need to synchronize separate files.

Mirror image

Use the Mirror command to reverse the camera view along its vertical axis.

Hide my image while recording

This closes the preview of your webcam recording so you don’t see your own image while recording.


You can add a short text to the preview or file, for example your name, exam identification etc.

Sanako Sign Lab is a standalone software but can be offered as a module for our Sanako Study 1200 and Sanako Study 700 language lab software.
