The invention discloses an inter-animal translation method. The method comprises the following steps: step 201, collecting and storing video information of behavior actions of an animal A and audio information of emitted sound through a translator terminal; step 202, sending the image information and the audio information of the translator terminal to a translator cloud; step 203, the translator cloud uses a translation model to identify the video information and the audio information of the animal A, wherein the identification result comprises a first label corresponding to the video information and the audio information of the animal A; step 204, the translator cloud queries in a label database according to the identification result and the animal type B, and sends the video informationand the audio information of the animal B corresponding to the first label back to the translator terminal as translation results; step 205, the translator terminal translates the translation result to the animal B in a video display and sound production mode. By means of the method, translation between animals of different species can be achieved.
