Tolerance Interval Analysis를 이용한 배경화자 없는 간단한 화자인증시스템에 관한 연구
On the Simple Speaker Verification System Using Tolerance Interval Analysis Without Background Speaker Models
초록
In this paper, we are focused to develop the simplified speaker verification algorithm without background speaker models, which will be adopted in the portable speaker verification system equipped in portable terminals such as mobile phone and PMP. According to the tolerance interval analysis, the population of someone's speaker model can be represented by a suitable number of selected independent samples of speaker model. So we can make the representative speaker model and threshold under the specified confidence level and coverage. Using proposed algorithm with the number of samples is 40, the experiments show that the false rejection rate is
