Abstract
A method and an electronic device for training a complex neural model of acoustic echo cancellation (AEC). The method includes: generating an anchor audio pair, a positive audio pair and a negative audio pair according to multiple near-end signals and multiple acoustic echo signals; utilizing the complex neural model to extract an anchor audio feature, a positive audio feature and a negative audio feature from the anchor audio pair, the positive audio pair and the negative pair, respectively; calculating a loss function according to the anchor audio feature, the positive audio feature and the negative audio feature; and tuning at least one parameter of the complex neural model according to the loss function.
