downloadFolder = matlab.internal.examples.downloadSupportFile("audio","SpeechEmotionRecognition.zip");

showing error:

Error using exist

The first input to exist must be a string scalar or character vector.

Error in matlab.internal.examples.downloadSupportFile (line 38)

if ~exist(localfile,'file')

Error in EmotionRec (line 39)

downloadFolder = matlab.internal.examples.downloadSupportFile("audio","SpeechEmotionRecognition.zip");

[Walter Roberson]

You appear to be using an older version of MATLAB. Use

downloadFolder = matlab.internal.examples.downloadSupportFile('audio','SpeechEmotionRecognition.zip');

Answer 2

[Brian Hemmat]

I can't reproduce this from my end (the download works fine).

Can you print the results of ver?

[EHIJAS KV]

kindly check the link mentioned below, the code of emotion recognition given in mathwork.

Link: https://ch.mathworks.com/help/deeplearning/ug/sequential-feature-selection-for-speech-emotion-recognition.html#mw_rtc_SequentialFeatureSelectionForSpeechEmotionRecognitionExample_245BAD07

the code line: downloadFolder = matlab.internal.examples.downloadSupportFile("audio","SpeechEmotionRecognition.zip"); is not working and the error shown earlier

@EHIJAS KV did you see where @Brian Hemmat said "Can you print the results of ver?"

Why did you not answer him? (Delete your liciense number when you paste it here)
