MATLAB: Testing classifying gender on LSTM

Question

I tried to recreate gender classification using LSTM Method for deep learning.

https://www.mathworks.com/help/audio/ug/classify-gender-using-long-short-term-memory-networks.html#GenderIdentificationExample-9

On the example, it show the prediction for all training data.

But I still confused on how to test a random sample .wav file fom the test dataset, so that my matlab can give specific prediction ouput of its gender labels.

I tried to add new line below and use predict, but it didn't work.

prediction = classify(net,sample_feature)

Can anyone explain or provide me link on how to test random file and give specific labels ouput?
