Introduction to Deep Learning for Audio Applications (Audio Toolbox)

Learn common tools and workflows to apply deep learning to audio applications.

Classify Sound Using Deep Learning (Audio Toolbox)

Train, validate, and test a simple long short-term memory (LSTM) to classify sounds.

Transfer Learning with Pretrained Audio Networks (Audio Toolbox)

Use transfer learning to retrain YAMNet, a pretrained convolutional neural network (CNN), to classify a new set of audio signals.

Speaker Identification Using Custom SincNet Layer and Deep Learning (Audio Toolbox)

Perform speech recognition using a custom deep learning layer that implements a mel-scale filter bank.

Dereverberate Speech Using Deep Learning Networks (Audio Toolbox)

Train a deep learning model that removes reverberation from speech.

Speech Command Recognition in Simulink (Audio Toolbox)

Detect the presence of speech commands in audio using a Simulink® model.
