EchoBharat models — licensing
=============================

This repository redistributes DERIVED weights from several upstream projects under
DIFFERENT licenses. There is no single license covering everything here. Honour each
component's terms separately.

------------------------------
EchoBharat's speech recognition uses models this repository does not contain:

  IndicConformer weights
      AI4Bharat  —  MIT License
  IndicConformer ONNX conversion
      parismitaglobalsolutions/indicconformer-sherpa-onnx  —  Apache License 2.0
      The conversion declares Apache-2.0 although the upstream weights are MIT.
      Anyone using those files should comply with both.

No model in this repository was trained here. Every weight is a quantized re-export of a
published checkpoint, and attribution belongs to the upstream authors named above.
