Introduction


The need for fast, efficient,
accurate, and robust means of recognizing people and
languages is of growing importance for commercial, forensic, and government
applications. The aim of this workshop is to continue to foster interactions among
researchers in speaker and language recognit
ion.


The Odyssey 20

Workshop on Speaker and Language Recognition was

held
on 25

28
June 2012
in Biopolis, Singapore.
This Odyssey
was

an ISCA Tutorial and Research
Workshop of the ISCA Speaker and Language Characterization SIG
.
It is

Scientific
Papers


A total number
6
5 papers were submitted
to Odyssey 2012
, scientific review process.
Compared to previous editions (39 papers in Martigny
-
94, 49 in Avignon
-
98, and 44 in
Crete
-
01, 79 in Toledo
-
04, 80 in

San Juan in 2006,

41

in Stelle
n
bosch 2008
, and

55 in
Brno 2010
), this is
above the

average
of 55 submissions from past years
.


Each paper was
reviewed
at least by 3

members of the Review
Committee 3), and the
final number of accepted papers was
51
, so the rejection rate was 2
2
%, which is a
rather high

rate compared with the previous editions (10.0% rejection rate in
Martigny
-
94, 10.5% in Avignon
-
98, and 9.1% in Crete
-
01, 22.7% in Toledo
-
04
, 25% in
San Juan
-
06 and
24.4
% in Stellenboshch
-
08
). This indicates increasing selectivity and
helps to improve the

scientific quality of the accepted papers.

Report from Odyssey 2012


Haizhou Li presented the organization of the workshop, the financial status of
the workshop
.

Odyssey 2012 was financially healthy due to 3 financial sponsors
from Singapore.

There were several discussions and recommendations for
actions by
the next Odyssey organizer.

Some members in the organizing committee are no longer active in
SpLC
. It
i
s suggested to refresh the list by seeking their confirmation.

b)

Some members in the cur
rent list of scientist committee didn’t respond to
the request for review. It is suggested to refresh the list by inviting
organizing committee to nominate new members. Scientific committee will
serve as the paper review committee.

c)

It is suggested that org
anizing committee and local organizers work on
invited speakers early to avoid a last minute rush.


b.

Proposal to host Odyssey 2014


a)

Tomi Kinnunen presented Joensuu Finland’s bid to host Odyssey 2014. Five
committee members unanimously supported the bid. Ody
ssey 2014 will be

for
its
“white nights” with a day temperature of 22 degree
Celsius
.
