Save Time with Forensic Voice Analysis when Every Moment Counts

Our numerous voice biometrics features save forensic experts countless hours otherwise spent listening to recorded audio evidence. The software helps to identify and differentiate voices by allowing you to easily compare multiple audio recordings at once—even if they’re obtained from different channels (i.e. microphones, telephone, etc). With advanced voice recognition, the software can separate different speakers’ voices in a mono recording and detect silence and speech in an acoustic signal. This makes it easier to determine who is speaking, and when, in any audio recording. Finally, it also identifies a speaker’s gender.

Text-independent comparisons and an intuitive graphical interface make it easy to organize, play and analyze audio with minimal effort. Experts can archive their analyses and access  them later. This software is compatible with the Windows operating system.

Compares two audio recordings to generate statistical scores and probability distribution graphics to serve as evidence.
