Embodiment Construction
[0052] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0053] Such as figure 1 As shown, the speech enhancement method based on two-dimensional spectrogram and conditional generative confrontation network provided by this embodiment includes the following steps:
[0054] Step 1, adding different types of noises with different signal-to-noise ratios in the training and testing speech signals to obtain noisy training and testing speech signals, the calculation formula is:
[0055] d(n)=s(n)+v(n)
[0056] Among them, d(n) represents the speech signal after adding noise, s(n) represents the monophonic speech signal, v(n) represents a certain type of noise signal under the specified signal-to-noise ratio, and n represent...
