Artificial intelligence (AI)-based voice sampling apparatus and method for providing speech style

An artificial intelligence (AI)-based voice sampling apparatus for providing a speech style, the apparatus comprising:

• a rhyme encoder configured to receive a user's voice to extract a voice sample, and analyze a vocal feature included in the voice sample;
• a text encoder configured to receive text for reflecting the vocal feature;
• a processor configured to classify the vocal feature of the voice sample input to the rhyme encoder according to a label, extract an embedding vector representing the vocal feature from the label, and generate a speech style from the embedding vector and apply the generated speech style to the text;
• and
• a rhyme decoder configured to output synthesized voice data in which the speech style is applied to the text by the processor,
• wherein the rhyme encoder divides the voice sample by a predetermined label and extracts the embedding vector for the label, and
• wherein the processor selects a voice sample closest to a mean value for each vector component of all voice samples in the label, from among a plurality of voice samples input from the user.
