Sustainability of the Initiative
We are committed to run this initiative for 10 years
given the size, complexity, and foundational impact of the language technology piece in India
Our core approach would continue to be a focus on
open sourcing datasets, models, and tools
Sustainability of the initiative would be based on donors recognising value generated through the yearly mandates
For each year, we would declare the Initiative's mandate - a set of key goals for datasets, models, and tools
Potential Donors
Govt's funding
Philanthropy
Corporate Research
Potential Donors

Focus on Speech - Our current roadmap
Release a joint speech-to-text model on 12 major
Indian languages in 2021
Create an automated approach to collect parallel
speech and text data from the web by mid 2022
Release efficient, privacy-preserving speech-to-text models for smartphones on 12 major languages by end 2022
