Abstract
A method for evaluating performance of a speech enhancement algorithm includes: acquiring a first speech signal including noise and a second speech signal including noise, wherein the first speech signal is acquired from a near-end audio acquisition device close to a sound source, the second speech signal is acquired from a far-end audio acquisition device far from the sound source, and the near-end audio acquisition device is closer to the sound source than the far-end audio acquisition device; acquiring a pseudo-pure speech signal based on the first speech signal and the second speech signal, as a reference speech signal; enhancing the second speech signal by using a preset speech enhancement algorithm, to obtain a denoised speech signal to be tested; and acquiring a correlation coefficient between the reference speech signal and the speech signal to be tested, for evaluating the speech enhancement algorithm.
