Oriental Language Recognition (OLR) 2021 Challenge

Oriental languages involve interesting specialties. The OLR challenge series aim at improve the performance of language recognition systems and speech recognition systems within multilingual scenarios. Following the success of OLR Challenge 2016, OLR Challenge 2017, OLR Challenge 2018, OLR Challenge 2019, and OLR Challenge 2020 the new challenge in 2021 focuses on more practical and challenging problems, with four tasks:

  • Task 1: constrained LID is a close-set identification task, which means the language of each utterance is among the known 13 target languages, but utterances were recorded in different environments. And only the data provided by the organizer can be used to build the LID system.
  • Task 2: unconstrained LID is also a close-set identification task, but test data from wild, which means utterances are obtained from real-life environments. It is therefore more challenging than the constrained task. In this task, any data (except the evaluation data) you can access is allowed to build the system.
  • Task 3: constrained multilingual ASR is a data resources constrained task, only the data provided by the organizer can be used.
  • Task 4: unconstrained multilingual ASR is a task with unconstrained data resources and any data can be used for training and optimization.

News

  • Jul. 23, challenge registration open.

Data

The challenge is based on two multilingual databases, OLR16-OL7 that was designed for the OLR challenge 2016, and OLR17-OL3 database that was designed for the OLR challenge 2017. For OLR 2021 Challenge, a standard test set OLR21-test is also provided.

OLR16-OL7 is provided by Speechocean (www.speechocean.com), and OLR17-OL3 is provided by Tsinghua University, Northwest Minzu University and Xinjiang University, under the M2ASR project supported by NSFC.

The features for OLR16-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 OLR17-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

For the OLR 2021 Challenge, the trials of the four tasks will be divided into two subsets: a progress subset, and a test subset. The progress subset will comprise 30% of the trials and will be used to monitor progress in the leaderboard. The remaining 70% of the trials will form the test subset, and will be used to generate the official results which are the base of the final ranking. The OLR21-test database is the standard test set for the OLR 2021 challenge, which contains two parts: OLR21-cross-domain-test and OLR21-wild-test.

  • OLR21-cross-domain-test: This subset is designed for three tasks: the constrained LID task, the constrained multilingual ASR task, and the unconstrained multilingual ASR task. It contains 13 languages, and was recorded by different recording equipments in different environments. The 13 languages are Indonesian, Japanese, Russian, Korean, Vietnamese, Mandarin, Cantonese (China), Sichuanese (China), Shanghainese (China), Hokkien (China), Tibetan (China), Kazakh (China), and Uyghur (China).
  • OLR21-wild-test: This subset is designed for the unconstrained LID task, which contains 17 languages: Indonesian, Japanese, Russian, Korean, Vietnamese, Thai, Malay, Telugu, Hindi, English (British and American), Kazakh (China), Tibetan (China), Uyghur (China), Mandarin, Sichuan (China), Shanghainese (China), Hokkien (China). Utterances in this subset are obtained from reallife environments.
