Hi @alvinzulham,
The current anomaly block for audio data was removed some time ago as it doesn’t work well well high-dimensional data.
What I’ll suggest is to create an anomaly class with random sounds/keywords that are not part of your other classes. Once deployed, you can add a check in your embedded application on the predicted label and filter out the anomaly class.
