AI4Bharat IndicConformer

What it is

IndicConformer is AI4Bharat's open-source ASR model family targeting India's 22 scheduled languages. Released under permissive licenses with weights on Hugging Face, the models are the natural starting point for any team that needs to self-host Indic STT rather than rely on a commercial API. The same lab also publishes IndicTrans and IndicBERT, so the broader pipeline is reachable. Best fit when the buyer is researchers and indian-language product teams who need open weights for fine-tuning. The honest caveat: conformer architecture is non-streaming by default; english is not in scope. As with any open-weights release, the integrator owns hosting, scaling, and SLA — but the licensing cost is zero and the model can be fine-tuned on in-house audio.
