ARTPARK-IISc/Vaani

VAANI is an India-representative multi-modal multi-lingual dataset. The current version (phase 1- 80 districts, phase 2- 40 districts) contains ~21,500 hours of spontaenous,image-prompted speech by 112.4K speakers across 120 districts, talking about 210K images covering 86 languages. From this audio data, 835 hours of transcribed data(text) is available, spanning almost evenly across the 120 districts.

Project Vaani, by IISc, Bangalore and ARTPARK, is capturing the true diversity of India’s spoken languages to propel language AI technologies for a truly inclusive Digital India. It was started with a vision to boost ML research and application capabilities in all Indian languages. We expect to create data corpora of over 150,000 hours of speech, part of which will be transcribed in local scripts, while ensuring linguistic, educational, urban-rural, age, and gender diversity (among other potential diversity characteristics). These diligently collected and curated datasets of natural speech and text from about 1 million people across all 773 districts of India will be open-sourced. The current version of the dataset that is open-sourced contains is from Phase 1. This unique dataset is also available through prestigious platforms such as Bhashini (under the National Language Translation Mission, MeiTY).

This initiative has been funded by Google.
