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: Disclosed is a text-to-speech (TTS) method enabling multiple speakers to be set. The present invention sets speaker information for the multiple characters with respect to a script composed to enable utterance by the multiple characters, and utilizes metadata including the speaker information corresponding to the multiple characters for speech synthesis, thereby realizing an audiobook which allows the multiple speakers to output speech utterance. In addition, the speaker information for the multiple characters may be set through Artificial Intelligence (AI) processing to thereby perform multi-speaker speech synthesis by a TTS device including an AI module.
