Classification: CPC G | IPC G

Claim 14:
15. A non-transitory computer-readable recording medium having recorded thereon a computer program, which, when executed by a server, cause the server to:
receive, from the client device through the communication interface, an input text input by a user,
identify a replacement target text to be replaced from among one or more words included in the input text,
generate a replacement text that is predicted to be uttered for the identified replacement target text by the user and has a phonetic similarity with the identified replacement target text,
generate one or more training text candidates by replacing, within the input text, the replacement target text with the generated replacement text, and
train a natural language understanding (NLU) model by using the input text and the one or more training text candidates as training data,
wherein the processor is further configured to:
convert the replacement target text into a custom wave signal by using a personalized text-to-speech (TTS) model, wherein the personalized TTS model is an artificial intelligence model trained to generate a wave signal from a text by reflecting personalized characteristics including at least one of age, gender, region, dialect, intonation, and pronunciation of the user,
output the custom wave signal, and
generate the replacement text by converting the custom wave signal into an output text using an automatic speech recognition (ASR) model.
