Public Lecture on the Application of Naturan Language Processing by Prof. Seiichi Nakagawa
BANDUNG, itb.ac.id - The Informatics Engineering major attempted to explore sensoric technologies by holing a public lecture on Natural Language Processing, with Prof. Seiichi Nakagawa, an artificial intelligence researcher from Toyohashi University of Technology, Japan, as key speaker.
He opened the lecture by firstly introducing the Toyohashi University of Technology and the various researches and scientific works he has done with his assistant, Prof. Kazumasa Yamamoto (on speech processing) and Prof. Masatoshi Tsuchiya (on natural language processing).
Speech Recognition
One of the notable researches Nakagawa has done before include one on speech recognition. In the lecture, he tried to widen the knowledge of the audience on the methods used in designing a learning material in Japanese and English. The basic concept of the project was to use a syllable-based acousstic model (a model used in the making of programs utilizing artificial intelligence).
Speaker Identification
Another material he spoke about was on speaker identification. Nakagawa elaborated how a program could acquire human voice among other interfering voices (music, noise, and others). The process was excruciatingly complex; it uses filters that differentiates the voice with others so that no mistake is made. He also stressed the importance of language model to narrow down the search of appropriate articulations in the dictionary stored inside the program's database.
