Abstract: The present disclosure relates to a method and system for end-to-end automated speech recognition on a digital platform. Said method comprises: (1) receiving, via a recorder [102], a speech input in a target domain; (2) processing, by a first sub-system [104], the speech input based on a data output from a second sub-system [106] and a pre-trained third sub system [108], wherein the pre-training of the third sub-system [108] is based on a historical audio data in a source domain retrieved from a memory unit [110]; and (3) generating, by the first sub-system [104], a text output for the speech input based on the processing of the first sub-system [104]. The method obtains a low-cost system and method for end-to-end automatic speech recognition with high accuracy.
