The models behind this service are published under a licence that asks for credit. This is that credit.
Speech recognition by NVIDIA Parakeet TDT 0.6B v3, © NVIDIA Corporation, used under CC-BY-4.0, which is offered without warranties. Modified: the published checkpoint has been converted to ONNX for inference, and quantised to int8 where a smaller model is served. The weights are otherwise unchanged; there has been no retraining or fine-tuning.
Speaker detection by NVIDIA Streaming Sortformer 4spk v2, © NVIDIA Corporation, used under CC-BY-4.0, which is offered without warranties. Modified: the published checkpoint has been converted to ONNX for inference. The weights are otherwise unchanged; there has been no retraining or fine-tuning.

The typefaces and the code highlighter are copies we serve ourselves, so a page here loads nothing from another host. Each licence travels with its files.

The service is built on open-source libraries, used unmodified. Their licences ask for notices to travel with copies of the software; this is a hosted service, and what leaves the building is a transcript, never a copy of the program, so no further notice is owed here.
A complete inventory is kept, and customers who need one for their own records are welcome to ask.
