7/28/2003 - Kane Computing can now offer speaker verification software solution for PC-based systems. The software is targeted at secure telephony, voice-based access systems, voice locks, childproof electronics, and other applications where it is necessary to identify a person by analysing his/her voice.
The speaker verification solution has two operating modes. In static mode, the user has to speak the password, and the SV system makes its decision on whether the user is legal. In dynamic mode, the user is required to speak a set of standard system keywords (e.g. numerals) in random order. Dynamic mode is considered significantly more reliable though lengthier.
Both direct and remote speaker verification - with live voice or via phone line - is supported by the software. User enrolment and verification can be performed under different acoustic conditions (quiet room, phone verification, etc.) Enrolment and verification thresholds are selectable, enabling an adjustable security level. To improve verification reliability, the algorithm also implements signal/noise ratio and non-linear distortion analysis.
The speaker verification software is available in the form of DLL libraries for Microsoft Windows. Custom porting to DSP or RISC platforms is performed on request.
