Abstract: A method for performing multi-language communication includes receiving an utterance, identifying a language of the received utterance, determining whether the identified language matches a preset reference language, applying, to the received utterance, an interpretation model interpreting the identified language into the reference language when the identified language does not match the reference language, changing, to text, speech data which is outputted in the reference language as a result of applying the interpretation model, generating a response message responding to the text of the speech data, and outputting the response message. Here, the interpretation model may be a deep neural network model generated through machine learning, and the interpretation model may be stored in an edge device or provided through a server in an Internet of things environment through a 5G network.

Abstract: A speech synthesis method and apparatus based on emotion information are disclosed. A speech synthesis method based on emotion information extracts speech synthesis target text from received data and determines whether the received data includes situation explanation information. First metadata corresponding to first emotion information is generated on the basis of the situation explanation information. When the extracted data does not include situation explanation information, second metadata corresponding to second emotion information generated on the basis of semantic analysis and context analysis is generated. One of the first metadata and the second metadata is added to the speech synthesis target text to synthesize speech corresponding to the extracted data. A speech synthesis apparatus of this disclosure may be associated with an artificial intelligence module, drone (unmanned aerial vehicle, UAV), robot, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G services, and the like.
