Log Spectral Amplitude Minimum Mean Square Error Speech Enhancement Algorithm (LSA-MMSE)

The Log Spectral Amplitude Minimum Mean Square Error (LSA-MMSE) speech enhancement algorithm incorporates voice activity detection (VAD) to further improve signal-to-noise ratio (SNR) and delivers excellent noise suppression performance. This algorithm is particularly effective for various types of stationary noise environments.

Processing Noisy Speech with Stationary Noise Using Spectral Subtraction Algorithm

Implementation of spectral subtraction algorithm in MATLAB environment for processing noisy speech containing stationary noise. The original speech file should be named "origin.wmv", while the processed output will be saved as "enhanced.wmv". The provided RAR archive contains pre-processed speech results; users can replace these with their own audio files by placing them in the same directory.
