TrainingSet/English contains no files with standard audio file extensions.
You need to change
ads = audioDatastore(output_dir, ...
'IncludeSubfolders',true, ...
'LabelSource','foldernames');
to explicitly have 'FileExtensions' name/value pair so that it can locate the files with the non-standard extensions.
Possibly TrainingSet/English is empty.

The error is happening on this line:
ads = audioDatastore(output_dir, ...
'IncludeSubfolders',true, ...
'LabelSource','foldernames');
and it happens because output_dir (which, based on your selections, is fullfile(pwd(),'TrainingSet','English')) and/or one or more of its sub-folders contains files whose extensions are not in the set listed under FileExtensions on this page.
You can avoid this error by specifying extensions of the files you want to include in your audioDatastore, e.g.:
ads = audioDatastore(output_dir, ...
'IncludeSubfolders',true, ...
'LabelSource','foldernames', ...
'FileExtensions',{'.wav','.mp4','.wot'});

@Mohammad Sultan
Audio file extensions, specified as a character vector, cell array of character vectors, string scalar, or string array. If you do not specify FileExtensions, then audioDatastore automatically includes all supported file types:
  • .wav
  • .avi
  • .aif
  • .aifc
  • .aiff
  • .mp3
  • .au
  • .snd
  • .mp4
  • .m4a
  • .flac
  • .ogg
  • .mov
  • .opus
