Enhancing Signal Strength for Real-Time Speech Signal through EMD
Objective
The objectives of this study is to develop a real-time speech enhancement framework using Empirical Mode Decomposition (EMD) to decompose and reconstruct speech signals for improved clarity. Optimize the algorithm by selectively processing intrinsic mode functions (IMFs) to boost signal strength and reduce noise interference. Validate the proposed method through objective performance metrics and real-time testing, comparing its effectiveness against conventional speech enhancement techniques.
Abstract
Empirical Mode Decomposition (EMD) is a practical technique for enhancing signal strength in real-time speech processing by adaptively decomposing non-stationary signals into intrinsic mode functions (IMFs). EMD is particularly useful in applications like speech recognition, voice communication, and hearing aids because it improves the clarity and intelligibility of speech signals by eliminating unwanted distortions and noise. The approach works by iteratively collecting IMFs and reconstructing the signal while preserving important speech features. This technique ultimately improves the quality of speech signal processing and transmission, ensuring a greater signal-to-noise ratio (SNR), reduced interference, and improved real-time performance.
Keywords: Speech Signals, Denoising Algorithm, Empirical Mode Decomposition (EMD), Signal-To-Noise Ratio (SNR).
