Implementation of Speech Enhancement Algorithm and its Wireless Transmission

Speech enhancement is concerned with processing noisy speech signals to improve the human perception of voice signals. The main goal of the speech enhancement algorithm is to reduce or remove the noise from a noisy speech sounding. By subtracting an approximation of the average noise spectrum from the noisy signal spectrum, the spectral subtraction speech enhancement algorithm restores the spectrum magnitude for signals seen in additive noise. This paper's main idea is to implement this algorithm on the TMS320C6713 Digital Signal Processor (DSP) and wireless transmission of the enhanced audio signal. Currently, a large number of the gadgets we use are wireless. As a result, in this study, we have suggested a technique for wirelessly transmitting speech signals utilizing an nRF module. The DSP-enhanced voice signal is input to the Arduino Uno ATmega328P controller using a sound sensor module. Data is down- and up-sampled using the controller, and wireless transmission is accomplished using an nRF module.
