This repository contains all the materials used in my Audio Machine Learning Workshop, designed for students and beginners who want to understand how computers process and analyze audio data.

Unlike many tutorials that jump directly into deep learning, this workshop starts from the very basics:

• What is sound?
• How does a computer "hear" audio?
• How is audio represented as numerical data?
• Why can't we directly use raw audio?
• How do we extract meaningful features?
• How can we build Machine Learning applications using audio?

The workshop combines theory, visual explanations, and hands-on coding to help learners understand the complete workflow of Audio AI.

Follow the complete journey of a recorded voice, from microphone input to machine learning prediction.

Build a strong conceptual foundation before diving into Machine Learning.

Topics include:

• What is sound?
• Audio as digital data
• Waveforms
• Sampling Rate
• Frequency
• Amplitude
• Feature Extraction
• MFCC
• Spectrograms

1. Predicting Audio (Yes / No Classification) - Build your first Audio Machine Learning classifier.

2. Custom Word Activator using Transfer Learning - Learn how to leverage powerful pretrained models for custom keyword detection.

3. Speaker Gender & Accent Identifier - Build an application capable of identifying speaker characteristics from voice recordings. Topics:

   • Speaker classification
   • Gender prediction
   • Accent recognition
   • Audio preprocessing
   • Feature extraction
   • Deep Learning inference

• Python
• Google Colab
• Librosa
• Matplotlib
• Scikit-learn
• PyTorch
• Hugging Face Transformers
• Streamlit

By completing this workshop, you will understand:

• How computers represent sound as numbers
• Audio preprocessing techniques
• Waveform visualization
• Sampling Rate and Frequency
• MFCC feature extraction
• Spectrogram generation
• Classical Machine Learning for audio
• Transfer Learning for audio applications
• Building complete end-to-end audio ML projects

This workshop emphasizes understanding before coding. - Every practical implementation is preceded by visual explanations and intuitive examples so learners understand why each step is necessary before implementing it.

One of the highlights of this workshop is the "Live Journey of My Voice" demonstration, where participants observe the complete transformation of speech into machine learning features.
