VOICE_GUI Interface Implementation of SOLA-Based Pitch Scaling Algorithm

This project references "SOLA-Based Pitch Scaling Algorithm by Fan Yuhua (Shanghai Jiao Tong University)" and implements the Synchronized Overlap-Add (SOLA) algorithm using MATLAB. The implementation performs pitch scaling while maintaining constant time duration, featuring modular code structure with key functions for audio analysis, frame overlapping, and cross-correlation-based synchronization. The VOICE_GUI interface provides interactive controls for pitch adjustment parameters and real-time audio processing visualization, making it suitable for beginners learning fundamental speech signal processing techniques.
