| Outline of Final Research Achievements |
In this research, we experimentally analyzed the effect of spoofing attacks by voice imitation on speaker verification systems and acoustical characteristics of the imitated voice. These analyses were conducted by using our original speech data consisting of professional and non-professional impersonators' imitated voice. The analysis results show that the voice imitation by non-professional impersonators significantly increases the success rate of spoofing attacks and the higher success rate is yielded by the professional impersonator's imitation. We also proposed a method for quantitatively evaluating the quality of voice imitation. The method reveals that the professional imitator efficiently approaches his voice characteristics towards the target speaker's voice.
