Web#To load an audio file, you will use tf.audio.decode_wav, which returns the WAV-encoded audio as a Tensor and the sample rate. #A WAV file contains timeseries data with a set number of samples per second. Each sample represents the amplitude of the audio signal at that specific time. WebWe then create the confusion matrix and assign it to the variable cm. T cm = confusion_matrix (y_true=test_labels, y_pred=rounded_predictions) To the confusion matrix, we pass in the true labels test_labels as well as the network's predicted labels …
