Can I use shorter training and testing utterances?

[youyou098888]

I notice that both training and testing utterances are 4seconds long and the inference is "the evaluation utterances are first chunked to 4-second segments and processed by the network, with 2-second overlapping between consecutive segments."

If I want to shink the input of the network, Is there any chance I can use them in shorter audio, say 200ms long?
Can I use 4-seconds for training and 200ms for inference?
If not, Can I use 200ms for training and 200ms for inference?

You can try. But I think 200ms may not be a good choice for training/inference, as context is not enough for the neural network to learn/predict.

I notice that both training and testing utterances are 4seconds long and the inference is "the evaluation utterances are first chunked to 4-second segments and processed by the network, with 2-second overlapping between consecutive segments."
