Oriental Language Recognition (OLR) 2017 Challenge

Oriental languages involve interesting specialties. The OLR challenge series aim 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 sets individual tasks for 1 second, 3 second and the original segments separately.

We will publish the results on a special session of APSIPA ASC 2017. See more details for the AP17 special session.
