In our increasingly litigious environment, the ability to search and disclose electronically stored information (ESI) is common place. Audio is often not considered in litigation, disputes or forensic data searches and may contain valuable information.
As with the eDisclosure process followed for more traditional forms of ESI, tools are now available to automate the process, review and analysis of audio recordings. CYFOR’s speech technology can accurately conduct complex searches for key words or phrases and reduce the time and resource needed to analyse audio recordings. Features include iterative search, file based tagging and dataset filtering.
