This dataset includes scripted and unscripted speech across various domains such as agriculture, health, finance, sports, transport, culture, society, and general topics. It is primarily designed for use in automatic speech recognition (ASR) tasks. Use of this dataset for any form of text-to-speech (TTS), voice cloning, voice synthesis, or any technology intended to replicate or generate human voices is strictly prohibited. These restrictions are in place until further notice. --- You can load a language (e.g., zul) using the 🤗 `datasets` library ```python from datasets import load_dataset # Load isiZulu configuration ds = load_dataset("dsfsi-anv/za-african-next-voices", "zul") ``` ## Available Fields | Field | Description | | --------------- | ---------------------------------------------------- | | `audio` | 48kHz mono `.wav` audio file (automatically decoded) | | `transcript` | Transcribed utterance | | `recorder_uuid` | Unique speaker ID | | `type` | Scripted or unscripted | | `domain` | Thematic domain (e.g., Health, Agriculture, etc.) | | `duration` | Duration of the clip in seconds | | `gender` | Speaker gender (if available) | | `age_range` | Speaker's age group (e.g., 18–29, 30–39) | | `...` ## Splits All data is split into: - `train` (85%) - `dev` (5%) - `dev_test` (5%) - `test` (5%) 🔒 – reserved for future shared tasks/public leaderboards _All splits are **speaker-disjoint** to ensure reproducibility and avoid data leakage._ --- ## License **Creative Commons Attribution 4.0 International (CC BY 4.0)** You are free to use, share, and adapt the data—with proper attribution to the South Africa NextVoices team. ## Intended Use - Training/fine-tuning ASR models - Developing inclusive speech technology for African users - Cross-lingual learning and low-resource transfer - Model evaluation and benchmarking ## ⚠️ Limitations and Ethical Use - Dialectal diversity and regional accents may not be fully covered - The dataset is not intended for surveillance or other harmful use - All use must comply with ethical AI principles --- ## Citations If you use Swivuriso in your work, please cite both of the below: ### Dataset ``` @dataset{za-african-next-voices- 2025, title = {The South African Next Voices Multilingual Speech Dataset}, author = {Vukosi Marivate and Kayode Olaleye and Sitwala Mundia and Nia Zion Van Wyk and Andinda Bakainga and Unarine Netshifhefhe and Mahmooda Milanzie and Hope Tsholofelo Mogale and Chijioke Okorie and Graham Morrissey and Dale Dunbar and Tsosheletso Chidi and Rooweither Mabuya and Andiswa Bukula and Respect Mlambo and Tebogo Macucwa}, url = {https://huggingface.co/datasets/dsfsi-anv/za-african-next-voices/}, url2 = {https://github.com/dsfsi/za-african-next-voices}, url3 = {https://www.dsfsi.co.za/za-african-next-voices/}, publisher = {Data Science for Social Impact Research Group}, year = {2025}, type = {dataset} } ``` ### Research Paper Will be available soon. ``` @dataset{swivuriso2025, title = {Swivuriso: Creating the South African Next Voices Multilingual Speech Dataset}, author = {Vukosi Marivate and Kayode Olaleye and Sitwala Mundia and Nia Zion Van Wyk and Andinda Bakainga and Unarine Netshifhefhe and Mahmooda Milanzie and Hope Tsholofelo Mogale and Chijioke Okorie and Graham Morrissey and Dale Dunbar and Tsosheletso Chidi and Rooweither Mabuya and Andiswa Bukula and Respect Mlambo and Tebogo Macucwa}, url = {TBD}, year = {2025}, } ```
