Embodiment Construction
[0035] like figure 1 As shown, the implementation steps of the complex domain speech enhancement method based on the generated confrontation network in this embodiment include:
[0036] 1) Obtain the voice with noise;
[0037] 2) adopt Cartesian coordinate representation to obtain the real number spectrum R and the imaginary number spectrum I of band noise after adopting Fourier transform of speech;
[0038] 3) Input the noisy real number spectrum R and imaginary number spectrum I into the generator of the pre-trained generative confrontation network, and encode the input IR composed of real number spectrum R and imaginary number spectrum I into a high semantic feature Encoder through the encoder Encoder of the generator IR ; High semantic feature Encoder IR The feature S with global information is output through the generator's self-attention mechanism layer self-attention IR ; Through the decoder Decoder of the generator, the feature S IR The real number spectrum and the...
