Disclosed is a pet sound service providing method using deep neural network machine learning-based artificial intelligence (AI). The method comprises: a step of allowing a management server to request recording and uploading of a sound for an opinion or emotion of a user′s pet to a pet application running on a user terminal; a step of allowing the pet application to upload the sound data of the user′s pet recorded by the requested opinion or emotion to the management server; a step of allowing the management server to train a deep neural network machine learning-based AI model with the uploaded opinion or emotional sound data; a step of allowing the management server to provide the trained AI model to the pet application; and a step of allowing the pet application to generate the pet sounds corresponding to the user input by using the AI model and output the same through the speaker. Accordingly, by using the deep neural network machine learning-based AI, it is possible to easily reproduce the opinions and feelings the user wants to convey to the pet with sounds which can be understood by the pet.
