目录
Oriental Language Recognition (OLR) 2018 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 2017 and OLR Challenge 2016, the new challenge in 2018 follows the same theme, but sets up more challenging tasks in the sense of:
- Short-utterance identification task: This is a close-set identification task, which means the language of each utterance is among the known 10 target languages. The utterances are as short as 1 second.
- Confusing-language identification task: This task identifies the language of utterances from 3 highly confusing languages (Cantonese, Korean and Mandarin).
- Open-set recognition task: In this task, the test utterance may be in none of the 10 target languages.
We will publish the results on a special session of APSIPA ASC 2018.
