Oriental Language Recognition (OLR) 2019 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, OLR Challenge 2017 and OLR Challenge 2018, the new challenge in 2019 follows the same theme, but sets up more challenging tasks in the sense of:

• Task 1: Short-utterance LID, where the test utterances are as short as 1 second.

• Task 2: Cross-channel LID, where test data is in different channels from the training set.

• Task 3: Zero-resource LID, where no resources are provided for training before inference, but several reference utterances are provided for each language.

We will publish the results on a special session of APSIPA ASC 2019.

• Challenge registration open.

Data

The challenge is based on two multilingual databases, AP16-OL7 that was designed for the OLR challenge 2016, and AP17-OL3 database that was designed for the OLR challenge 2017. For AP19-OLR, a development set AP19-OLR-dev is also provided.

AP16-OL7 is provided by SpeechOcean (www.speechocean.com), and AP17-OL3 is provided by Tsinghua University, Northwest Minzu University and Xinjiang University, under the M2ASR project supported by NSFC.

The features for AP16-OL7 involve:

• Mobile channel
• 7 languages in total
• 71 hours of speech signals in total
• Transcriptions and lexica are provided
• The data profile is here
• The License for the data is here

The features for AP17-OL3 involve:

• Mobile channel
• 3 languages in total

• Tibetan provided by Prof. Guanyu Li@Northwest Minzu Univ.
• Uyghur and Kazak provided by Prof. Askar Hamdulla@Xinjiang University.

• 35 hours of speech signals in total
• Transcriptions and lexica are provided
• The data profile is here
• The License for the data is here

AP19-OLR-dev is provided for the development of the 3 tasks respectively:

• Task 1: AP19-OLR-dev doesn't include short-duration speech data specifically, but short-duration test set in previous challenges can be used for development.
• Task 2: for the cross-channel task, AP19-OLR-dev includes a subset which contains 500 utterances for per target language.
• Task 3: in the zero-resource subset of AP19-OLR-dev, 3 new languages are provided with 5 utterances for enrollment and 500 for test. Note that the 3 languages in the final test are different from those in the development.
