Build a speech classification model to distinguish human speech from voicemail messages using CNNs and mel-spectrograms

intermediate Published 27 Apr 2026
Action Steps
  1. Collect a dataset of human speech and voicemail messages
  2. Preprocess audio data using mel-spectrograms
  3. Build a CNN model to classify speech patterns
  4. Train and test the model using the collected dataset
  5. Evaluate the model's performance using metrics such as accuracy and F1-score
