Conferences
1.1
IEEE
I
joined the SLTC (Speech and Language
Technical Committee) of the IEEE Signal Processing Society from 2010, and a
member of the review committee of
the international conference, ICASSP, from 2009.
1.2
INTERSPEECH
INTERSPEECH,
an international conference on speech communication, took place in Japan
(Makuhari) in 2010, and I participated as an organizing committee (chair of finance) as well as a presenter. I
stayed at a hotel near the conference venue to work as the chair of finance.
The work was great experience. Three research papers were presented from Arai
Laboratory [2010_06, 2010_07, 2010_08]. Two of those were
presented by myself at special sessions, “Fact
and Replica of Speech Production” and “Speech
Intelligibility Enhancement for All Ages, Health Conditions and Environments.”
Each name of the committee members were called out at the closing ceremony, and
received gifts from the conference chair Professor Keikichi Hirose.
