Multilingual text-to-speech synthesis

A system for multilingual text-to-speech synthesis, comprising:

• a memory;
• and
• at least one processor connected to the memory and configured to execute at least one computer-readable program included in the memory,
• wherein the at least one computer-readable program includes instructions for:
• receiving an articulatory feature of a speaker regarding a first language;
• receiving an input text of a second language;
• and
• generating output speech data for the input text of the second language that simulates the speaker's speech by inputting the input text of the second language and the articulatory feature of the speaker regarding the first language to a single artificial neural network multilingual text-to-speech synthesis model,
• wherein the single artificial neural network multilingual text-to-speech synthesis model is generated by learning similarity information between phonemes of the first language and phonemes of the second language based on a first learning data of the first language and a second learning data of the second language, and
• the first learning data does not include a language identifier for the first language, and
• the second learning data does not include a language identifier for the second language.
