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.

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)

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