It is very important that we create reference templates to recognize speech of speeker-independent as convergence as possible vocal tract variation of each speaker. We used to clustering technique for this and creation rule of reference templates to be cluster centers is key point of thema. In this paper, we created reference tempaltes using the minimax for existance and MMS technique suggested in this study. Also, we created reference template until top 3 and compared to recognition result. When we create 3 reference templates recognition rate is 91.6% for minimax and recognition rate is 95.8% for MMS.
