Hi Divya,

Please click the "open this example" button on the top right corner of the example. The "helperExtractAuditoryFeatures" function is a local function to the example. When you click the "open this example" button, the example is opened in a temporary directory and all necessary helper files are placed on path.

Thanks,

Brian

I sense two possible reasons:

1. Deep learning toolbox in not installed. (Type "ver" in the command window, it shows all installed toolboxes)
2. You are using earlier version of MATLAB (prior 2017a)

[Divya Singh]

nope. I have 2019a and have deep learning toolbox installed. is "helperExtractAuditoryFeatures" a built in function?
