Abstract: A speech recognition method includes: obtaining speech information; and determining beginning and ending positions of a candidate speech segment in the speech information by using a weighted finite state transducer (WFST) network. The candidate speech segment is identified as corresponding to a preset keyword. The method also includes clipping the candidate speech segment from the speech information according to the beginning and ending positions of the candidate speech segment; detecting whether the candidate speech segment includes a preset keyword by using a machine learning model; and determining, upon determining that the candidate speech segment comprises the preset keyword, that the speech information comprises the preset keyword.

Abstract: A server system with one or more processors and memory obtains, from a client device, a card image which includes an image of a card, and identifies a card configuration type corresponding to the card in the card image based on a database of stored card configuration types. Each stored card configuration type in the database is associated with layout information regarding respective features and information regions for the stored card configuration type. In accordance with the identified card configuration type, the server system determines one or more information regions of the card image containing respective card information of the card. The server system extracts at least a portion of the card information of the card from the one or more information regions of the card image and transmits, to the client device, at least the extracted portion of the card information.
