The present disclosure provides a method, apparatus for implementing a far-field speech function, system and a storage medium, wherein the method comprises: a speech detecting unit located on a smart device performing speech signal detection in real time; upon detecting an awakening word, the speech detecting unit awakening an algorithm unit located on the smart device and being in a standby state; the speech detecting unit transmitting the obtained speech signal to the algorithm unit so that the algorithm unit performs arithmetic processing for the speech signal in a predetermined manner, and sends a processed speech signal to a control system of the smart device, to complete a corresponding control operation. The solution of the present disclosure can be applied to save energy consumption and improve the acoustic effect, break away from the constraints of the remote controller and facilitate the user's operation.
