The Security Voice-code Access software component provides robust access control based on voice recognition technology. With two operation modes, users can choose between a specific pass-code sentence or individual voice fingerprints for secure access. Developed using fingerprint and spectrogram concepts, this software ensures reliable access control for up to 8 users.
- Access is granted only upon speaking a specific pass-code sentence.
- Valid passcodes include "Open middle door", "Unlock the gate", and "Grant me access".
- Access is granted based on individual voice fingerprints.
- Users can select which of the original 8 users are granted access.
- Users can configure access settings, including selecting individuals granted access in Mode 2.
- Initiates voice recording for the pass-code sentence.
- Displays the spectrogram of the spoken voice-code for analysis.
- Provides a summary of analysis results, including:
- A table showing the match percentage of the spoken sentence with each saved passcode sentence.
- A table showing the match percentage of the spoken voice with each of the 8 saved individuals.
- UI element indicating whether access is granted or denied based on algorithm results.
- Python: Programming language used for development.
- NumPy: For numerical operations and array manipulations.
- Matplotlib: For creating visualizations, including spectrogram display.
- SciPy: For scientific computing functions, including signal processing.
- SoundFile: For reading and writing audio files.
This project was supervised by Dr. Tamer Basha & Eng. Abdallah Darwish, who provided invaluable guidance and expertise throughout its development as a part of the Digital Signal Processing course at Cairo University Faculty of Engineering.
