Abstract
The present disclosure provides a method, an apparatus and a device for recognizing voice endpoints. In the method of the present disclosure, a start point recognition model and a finish point recognition model are obtained by training a cyclic neural network with a start point training set and a finish point training set, respectively, and a voice start point frame among audio frames is recognized according to each of acoustic features of the audio frames and the start point recognition model, thereby avoiding affecting a delay time of the finish point frame recognition while ensuring the accuracy of the start frame recognition as high as possible; and a voice finish point frame among the audio frames is recognized according to the acoustic features of the audio frames and the finish point recognition model.
