Abstract

Researching on the basic theory of HHT and its application in terms of speech enhancement, with the problem of poor adaptability and flexibility of the hard threshold de-noising algorithm, we present an improved soft threshold HHT speech enhancement algorithm. Through MATLB software simulation to explore the enhanced situation of noisy speech signal in different SNR, the simulation results proved that the definition and speech intelligibility of enhanced speech signal which enhanced by soft threshold HHT is higher. The new method has strong applicability in the field of speech enhancement.
