DESCRIPTION
Artificial audition recently became popular in mobile robotics in order to enhance the human-robot interaction. Speech recognition is the main field of interest whereas speaker recognition receives little attention. The ManyEars system (based on the AUDIBLE project) allows a mobile robot to localize, track and separate multiple simultaneous sound sources. This system uses an array of eight microphones disposed in a cubic shape. This speaker recognition system, named WISS (Who IS Speaking), is coupled to the ManyEars system. This speaker recognition system is robust to noise and dynamic environments. Parallel model combination (PMC) and masks are used to increase the identification rate within a noisy environment. A confidence value is also introduced to weight the obtained identifications. The simplicity of this system makes it suitable for real-time applications on a General Purpose Processor (GPP).
