| Research Abstract |
Spoken language contains speaker characteristics and contents related to privacy information such as personal names. In this study, we developed mixed sound separation techniques based on Vector Quantization and Non-negative Matrix Factorization (NMF), elimination technique of only speech in mixed sound and conversion technique of speaker characteristics. Finally, we developed a personal name detection/elimination method based on the modification of a language model.
