@bchinnari Sorry I missed the issue and thanks for the question. No. MarbleNet is using MFCC in vad_infer.py. Pleasev have a look at [model yaml file ](https://github.com/NVIDIA/NeMo/blob/main/examples/asr/conf/marblenet/marblenet_3x2x64.yaml#L58) For [vad_multilingual_marblenet]( https://catalog.ngc.nvidia.com/orgs/nvidia/teams/nemo/models/vad_multilingual_marblenet)...

Hi @bchinnari You can find the processor [here](https://github.com/NVIDIA/NeMo/blob/main/nemo/collections/asr/models/classification_models.py#L137).

@findkim Could you please run code linter and merge the PR? `python setup.py style --fix`
