Would you like to spend less time manually listening through audio footage?
Audio and video evidence should not sit outside the investigative workflow.
When interviews, phone messages, body-worn video and recorded conversations have to be reviewed manually, investigators lose time before they even know what is in the material.
S21 Transcriber gives investigators more ways to understand spoken evidence faster.
Building on its successful deployment to date, S21 Transcriber v2.0 is further enhanced with:
- Automatic speaker detection
- AI-powered conversation summary
- Accurate multi-language translation
- Speaker emotion and personal identification detection
And to top it off, all of this is offline, rapid, and accurate.

Used by forces around the world, S21 Transcriber is built for the evidence investigators deal with every day: interviews, phone messages, body-worn video and more. It helps teams move from manual listening to structured intelligence – without replacing investigator judgement.
S21 Transcriber works directly with S21 CCTV and S21 VisionX, enabling you to transcribe and search video evidence quickly, accurately and fully offline.
