Methods, systems, and apparatus, including computer programs encoded on computer storage media relate to a method for acoustic echo cancellation. The system inputs one or more signal representations into an acoustic echo cancellation network comprising one or more network blocks to generate a mask, each network block comprising one or more convolutional blocks, each convolutional block comprising one or more neural networks. The system combines the mask and a near-end audio signal representation to generate an echo-cancelled audio signal representation. The system generates an echo-cancelled audio signal based on the echo-cancelled audio signal representation.

Real-time low-complexity echo cancellation

Methods, systems, and apparatus, including computer programs encoded on computer storage media for generating echo recordings. The system receives, by an autoencoder, an audio signal representation that represents an audio signal and a target echo embedding that comprises information about a target room. The autoencoder comprises an encoder and a decoder. The system generates, by the encoder, a content embedding and an estimated echo embedding. The system generates, by the decoder, an echo recording representation based on the content embedding and the target echo embedding.
