labels_dict is considering files which are not actually labels.

[meetgandhi123]

The labels_dict is considering some folders which are not really useful. By considering all the folders in the Speech_Command_V0.02 folder like the following:

• background_noise
• testing_list.txt
• validation_list.txt.....

The labels index are not just 0-34 but from the range 0-40.

From:

labels_dict=os.listdir(train_audio_path)

output:
labels_dict = ['tree', 'cat', 'go', 'left', 'yes', '.DS_Store', 'sheila', 'learn', 'stop', 'backward', 'seven', 'follow', 'zero', 'three', 'down', 'no', 'up', 'six', 'four', 'nine', 'LICENSE', 'happy', 'validation_list.txt', 'background_noise', 'wow', 'visual', 'house', 'README.md', 'off', 'five', 'dog', 'one', 'eight', 'testing_list.txt', 'on', 'two', 'marvin', 'bird', 'forward', 'right', 'bed']

To:

labels_dict=list(set(labels))
labels_dict = ['tree', 'cat', 'go', 'left', 'yes', 'sheila', 'learn', 'stop', 'backward', 'seven', 'follow', 'zero', 'three', 'down', 'no', 'up', 'six', 'four', 'nine', 'happy', 'wow', 'visual', 'house', 'off', 'five', 'dog', 'one', 'eight', 'on', 'two', 'marvin', 'bird', 'forward', 'right', 'bed']

Hi,

Yes. You are correct. This code does have that issue. When I wrote it I actually removed those files manually at the beginning but never mentioned it in the repository.
