# Dataset Details |
|
|
|
|
|
This is dataset of speech translation task for Bemba-to-English Language. This dataset is acquired from (Big-C)[https://github.com/csikasote/bigc] github repository. |
|
|
Big-C is a large conversations dataset between Bemba Speakers based on Image [1]. This dataset provide data for speech translation. |
|
|
|
|
|
# Preprocessing Steps |
|
|
|
|
|
Some preprocessing was done in this dataset. |
|
|
|
|
|
1. Drop some unused columns other than audio_id, sentence, translation, and speaker_id. |
|
|
2. Investigate duplicate values (we still keep the duplicate data because that data have different audio quality). |
|
|
3. Remove test data that have overlap in train or val set. |
|
|
4. Cast audio column into Audio object. |

abstract = "We present BIG-C (Bemba Image Grounded Conversations), a large multimodal dataset for Bemba. While Bemba is the most populous language of Zambia, it exhibits a dearth of resources which render the development of language technologies or language processing research almost impossible. The dataset is comprised of multi-turn dialogues between Bemba speakers based on images, transcribed and translated into English. There are more than 92,000 utterances/sentences, amounting to more than 180 hours of audio data with corresponding transcriptions and English translations. We also provide baselines on speech recognition (ASR), machine translation (MT) and speech translation (ST) tasks, and sketch out other potential future multimodal uses of our dataset. We hope that by making the dataset available to the research community, this work will foster research and encourage collaboration across the language, speech, and vision communities especially for languages outside the {``}traditionally{''} used high-resourced ones. All data and code are publicly available: [\url{https://github.com/csikasote/bigc}](\url{https://github.com/csikasote/bigc}).", |
