Abstract(in English) | This paper describes an unsupervised and incremental speaker adaptation method. In practical applications, environmental changes for each adaptation utterance often degrade the speaker adaptation performance. To cope with this problem, the proposed method first cancel the effect of environmental differences for each utterance by using REALISE. Then we apply speaker adaptation with autonomous control using tree structure. The evaluation experiment was carried out for the utterances recorded from six speakers under three conditions in a vehicle environment. For the purpose of simulating rapidly changing environment, any two of the adjacent utterances are presented. In different conditions to the adaptation process. The evaluation results were 79%, 90%, and 95% for without processing, only applying REALISE, and proposed method after 100 words adaptation, respectively. |
