Voice Pathology Detection

Graduation project for Ain shams Scientific Computing general program

Table of Contents

Introduction

Our graduation project, Voice Pathology Detection, is a program designed to assess the health of a person's voice and classify voice disorders using both Machine Learning (ML) and Deep Learning (DL) techniques.

The human voice is a powerful tool for communication, but voice disorders can significantly impact a person's ability to communicate effectively. Early detection of voice pathologies is crucial for timely intervention and appropriate treatment. Our project aims to provide a valuable tool for identifying voice disorders by analyzing audio recordings of voice samples.

We leveraged the power of ML and DL algorithms to develop a model capable of distinguishing between healthy and pathological voice characteristics. By utilizing these advanced techniques, we sought to create a reliable and accurate system that could aid in the early diagnosis of voice disorders, potentially improving the quality of life for individuals affected by such conditions.

Throughout the development process, we focused on creating an intuitive and user-friendly interface that allows users to upload audio samples for analysis. The system then performs a comprehensive assessment, providing valuable insights into the health of the voice and identifying any potential voice pathologies.

By combining the fields of ML and DL, our graduation project aims to contribute to the field of voice pathology detection, supporting healthcare professionals and individuals alike in understanding and addressing voice disorders.

System Architecture

Technologies Used

  • Python
  • Librosa
  • Keras
  • TensorFlow
  • Pyqt5
  • Sqlite3
  • NumPy

Dataset

we utilized the Saarbrucken database (SVD) to train and evaluate the model. SVD is german database contains a collection of voice recordings from individuals with and without voice pathologies. It contains audio samples of various durations and different types of voice disorders. Recorded as Sessions

Session Details:

  1. Vowels /i, a, u/ produced at normal, high, and low pitch;
  2. Vowels /i, a, u/ with rising–falling pitch; and
  3. Sentence “Guten Morgen, wie geht es Ihnen?” (“Good morning, how are you?”).
