Perform VAD for my audio with this model
Hello, i want to try the code for test one wav file:
python NeMo/examples/asr/vad_infer.py  --vad_model=vad_marblenet.nemo --dataset=/fullpath/to/manifest/ --out_dir='frame/demo' --time_length=0.63

but i don't know what is /fullpath/to/manifest/ , it is json file ? 
i construct one json file, The contents are as follows：
{"audio_filepath": "/source/c0/speech/data/google_dataset_v2/google_speech_recognition_v2/bird/b65f6015_nohash_0.wav", "duration": 0.63, "label": "infer", "text": "_", "offset": 0}
but get error. 
So, i want to know how to construct /fullpath/to/manifest/ for my one wav file, Thank you for your guidance!
