| Outline of Final Research Achievements |
Most of ASR systems exist today are still tuned by minimizing word error rate, in which all errors from any words like functional words or fillers are treated in a uniform manner. In fact, the impact of all errors is not the same, but how big and differences are the impact are still unknown. To align with human perception, in this research I propose to utilize the event-related brain potential (ERP) studies into ASR framework, in which the human cognitive process during language comprehension is directly analysis and the possibilities to incorporate within ASR framework are investigated. We were successfully perform the ERP experiments given the ASR results, and we can confirmed that a difference occurs in the EEG/ERP signal when perceiving the communication failure factor. Furthermore, we can learn also how to incorporate different knowledge in ASR framework. We also have opportunities to collaborate with some research institutes from Indonesia, Vietnam, and France.
