Oriental Language Recognition (OLR) 2017 Challenge

Oriental languages involve interesting specialalities. The OLR challenge series aims at boosting language recognition technology for oriental languages. Following the success of OLR Challenge 2016, the new challenge in 2017 follows the same theme, but sets up more challenging tasks in the sense of:

• more languages: OLR 2016 involves 7 languages, OLR 2017 involves 10 languages.
• shorter speech segments. OLR 2017 set individual tasks for 1 second, 3 second, 5 second segments separately.

As the first OLR challenge, we will publish the result on a special session of APSIPA 2017. See more details for the AP17 special session.
