Overview

The voice matching in VoiceGridLocal system is accomplished through the utilization of the STC exclusive methods of processing, segmentation, feature extraction and identification of voice samples. This ensures the highest levels of accuracy and provides an additional and valuable tool in assisting in investigations where voice evidence may be present such as:

  • Kidnapping
  • Extortion
  • Domestic Violence
  • Terroristic Threats
  • Prank or False Report Calls
  • Corruption
  • Drug Trafficking
  • Gang & Organized Crime
  • Abuse of Emergency or 911 Communication Channels

VoiceGrid Local is ideal for agencies with a larger voice database requirement but with only the need for a stand-alone system or multiple workstations within the same facility or campus. Additionally VoiceGridLocal can be delivered as either a software-only solution to be installed on customer provided hardware or as a full turn-key solution including both hardware and software.

The turn-key solution delivers additional benefits by providing out-of-the-box plug and play capabilities. This will allow the user to quickly utilize the system and begin immediate operations without having to tax their existing IT infrastructure or resources. Additionally it will alleviate any compatibility issues with existing hardware and be pre-configured to the exact specifications required.
