Implementation of Speech Enhancement Algorithm on Hardware platform
Manasi Lehekar, Vidya Nitin More · 2022
An attractive study topic that addresses signal Noise is Speech signal. Speech enhancement processes Noisy speech signal to improve the human perception of speech. The purpose of the paper is to effectively ensure speech quality. To enhance the signal's quality, approximate the Noise spectrum's average from the Noisy signal spectrum, Spectral Subtraction speech enhancement algorithm restores the spectrum magnitude for signal. The objective assessment like SNR and PESQ has been calculated using simulations. The better speech quality obtained in results. A TMS320C6713 digital signal processor which seems to be good platform has been chosen to implement the selected algorithm. Real-time implementation is carried out on PC using MATLAB While the embedded implementation is carried out on Texas Instruments TMS320C6713 DSP utilizing Spectrum Digital Incorporation's DSP Starter kit- DSK6713
