- Title
Optimized Technique for Speech Noise Elimination Using Traditional Spectrum Subtraction.

- Abstract
The spectrum subtraction is the classical algorithm and the most common technology to eliminate the noise from the speech, which is dealing with broadband noise. It subtracts the Noisy Speech from the noise spectrum estimation, and generates the enhanced speech signal. The traditional spectrum subtraction suppresses this noise and improves the signal to noise ratio. Based on MATLAB, the spectrum subtraction algorithm was implemented, and results of traditional spectrum subtraction were compared with different noise conditions. Simulation shows that the improved form of spectrum subtraction can effectively reduce the background noise and improve signal to noise ratio..
