Abstract(in English) | Currently, most speaker identification methods have been performed by i-vectors which represent the features of unique speakers. Since i-vectors of utterances are supposed to be distributed on a surface of a hypersphere, it is possible to identify the speaker by using cosine similarity of i-vectors. In this manuscript, we suggest a new approach employing weak learners that significantly contribute to the field of machine leaning to improve the accuracy of the recognition in recent years. Especially, ensemble learning methods such as Bagging and Random Forest are examined and validated. |
