단어빈도와 단어규칙성 효과에 기초한 합성음 평가

The text-to-speech system assessment based on word frequency and word regularity effects

In the present study, the intelligibility of the synthesized speech sounds was evaluated by using the psycholinguistic and fMRI techniques, In order to see the difference in recognizing words between the natural and synthesized speech sounds, word regularity and word frequency were varied. The results of Experiment1 and Experiment2 showed that the intelligibility difference of the synthesized speech comes from word regularity. There were smaller activation of the auditory areas in brain and slower recognition time for the regular words.
