Description: This project collected text and speech corpora for three languages in Kenya: Kiswahili, Dholuo and 3 Luhya dialects (Lumarachi, Logooli and Lubukusu). Primary data was collected from the respective language communities, which included Indigenous stories and narratives from student compositions, native language media stations, and publishers – in order to include genres of texts representative of everyday language use in the communities. A total of 4,442 texts were collected: 2909 for Swahili, 546 texts for Dholuo, 483 texts for Lumarachi, 135 texts for Lubukusu, and 359 texts for Logooli. A total of 1,152 files containing spontaneous speech data were collected, which total to 176 hours, 29 minutes, and 46 seconds: 104 files (19 hours, 10 minutes, 57 seconds) for Swahili, 512 files (99 hours, 3 minutes, 8 seconds) for Dholuo, 138 files (15 hours, 37 minutes, 46 seconds) for Lumarachi, 354 files (30 hours, 11 minutes) for Lubukusu, and annotated 44 files (12 hours, 26 minutes, 55 seconds) for Lulogooli.

Description: This project developed a Part of Speech (POS) Tagged dataset of 2 languages in Kenya: Dholuo and 3 Luhya dialects (Lumarachi, Lulogooli, and Lubukusi). The project tagged approximately 143,000 words, which includes about 50,000 words for Dholuo, 27,900 words for Lumarachi, 34,300 words for Logooli, and 30,900 words for Lubukusu words.

Description: This project produced a speech dataset that includes both read and spontaneous speech recordings, recorded in Kenya with native Swahili speakers, and corresponding transcripts. In total, the dataset includes 27 hours, 31 minutes, 50 seconds of speech data from 26 speakers (19 females and 7 males). The recordings are of the following audio format: .wav, 16 bits, 16kHz, mono and Little Endian. Of the total recordings, 26 hours, 32 minutes, and 37 seconds represent the read speech data while 59 minutes, 13 seconds represent the spontaneous speech recordings. Additionally, this dataset includes a phonelist file containing all the Swahili phones as used by KenCorpus. This phone-list file is crucial, as its contents have been used to create the KenCorpus Swahili lexicon-phone dictionary, which contains all the words in the KenCorpus transcripts with their corresponding pronunciations as per the Swahili phones in the phone-list. The lexicon-phone dictionary contains about 30,000 words.

Description: This project produced a parallel corpus between Swahili and two other Kenya Languages: Dholuo  and 3 Luhya dialects (Lumarachi, Logooli and Lubukusu). A total of about 12,400 sentences were translated to Kiswahili from a sample of Dholuo and Luhya texts (1,500 Dholuo-Kiswahili sentence pairs and 10,900 Luhya-Kiswahili sentence pairs).

Description: This project produced a large Machine Reading Comprehension dataset for the Kiswahili Language. A total of 7,526 Question-Answer (QA) pairs were developed based on 1,445 Swahili story texts. Each text has at least 5 QA pairs, where the questions were written based on the story, and the answers are either a single word or a short text.

Description: This speech dataset for the Ghanian languages Akan (Akuapem Twi, Asante Twi, Fante) and Ga includes 104,000 utterances (speech) across the four dialects/languages with approximately 200 speakers per dialect/language. This amounts to about 148 hours of speech in total. The dataset was developed to support the development of financial applications in native Ghanaian languages to allow illiterate and semi-literate people to fully benefit from digital financial services. Secondly, it aims to answer research questions related to domain-specific vs. general-purpose dataset development, dialects, as well as NLP system development in low resource settings.

Description: This dataset is the first spoken corpus of labelled and unlabeled datasets for Igbo Natural Language Processing (NLP) tasks. It consists of approximately 40 hours of naturally occurring Igbo speech that is representative of all the dialects of Igbo. The dataset lays the foundation for Igbo NLP tasks such as machine translation, tree bank, speech-to-text, automatic POS tagging, digital dictionary, and automatic spelling checker.

Description: Makerere University has created text and speech datasets for low-resourced East African Languages in Uganda, Tanzania, and Kenya. This dataset contains 10,000 parallel sentiment-tagged sentences, 100,000 Kiswahili sentences, 100,000 Luganda sentences, 40,037 Acoli sentences, and 39,999 Lumasaaba sentences. On Common Voice, the text dataset comprises 100,000 Luganda sentences and 100,000 Swahili sentences. The text datasets can be used for building machine translation, next-word predictor/auto-completion, topic modeling and classification, sentiment analysis, and language models. The Luganda and Swahili voice datasets can empower entrepreneurs to innovate around existing gaps in their communities to build systems for visually impaired or physically handicapped people, native language tutors, medical transcription tools, and more. Application developers interested in translation engines, text editors, and text and grammar spelling systems in the East African community will benefit from the datasets.
