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.
