	Co-organized by Speech Committee (SP) of The Institute for Electronics, Information and Communication Engineers (IEICE) / The Acoustical Society of Japan (ASJ), Special Interest Group for Spoken Language Processing (SLP) of Information Processing Society of Japan (IPSJ), and Advanced Telecommunication Research Institute(ATR). Co-sponsored by the IEEE Signal Processing Society Japan Chapter.

	WORKSHOP THEME
		The Hidden Markov Model has been widely used for speech recognition. However, its performance significantly degraded in adverse environment, and when speech is highly spontaneous. Most attempts to overcome these problems are effective only in special applications. Consequently, there is a strong demand for a new modeling scheme beyond HMMs, that is based on comprehensive understanding of the inner nature of speech. One promising approach is to employ statistical methods, which make full use of large speech corpora and provide large computational power. In this workshop, we will discuss the exploratory research being pursued in this direction and to attempt to foster scientific insight into statistical modeling for speech recognition.
