    Abstract: An electronic apparatus and a controlling method thereof are provided. The electronic apparatus includes a microphone; a memory configured to store a text-to-speech (TTS) model and a plurality of evaluation texts; and a processor configured to: obtain a first reference vector of a user speech spoken by a user based the user speech being received through the microphone, generate a plurality of candidate reference vectors based on the first reference vector, obtain a plurality of synthesized sounds by inputting the plurality of candidate reference vectors and the plurality of evaluation texts to the TTS model, identify at least one synthesized sound of the plurality of synthesized sounds based on a similarity between characteristics of the plurality of synthesized sounds and the user speech, and store a second reference vector of the at least one synthesized sound in the memory as a reference vector corresponding to the user for the TTS model.

    Abstract: An electronic device and a controlling method of the electronic device are provided. The electronic device acquires text to respond on a received user's speech, acquires a plurality of pieces of parameter information for determining a style of an output speech corresponding to the text based on information on a type of a plurality of text-to-speech (TTS) databases and the received user's speech, identifies a TTS database corresponding to the plurality of pieces of parameter information among the plurality of TTS databases, identifies a weight set corresponding to the plurality of pieces of parameter information among a plurality of weight sets acquired through a trained artificial intelligence model, adjusts information on the output speech stored in the TTS database based on the weight set, synthesizes the output speech based on the adjusted information on the output speech, and outputs the output speech corresponding to the text.

    Abstract: A method for controlling an electronic device includes obtaining a text, obtaining, by inputting the text into a first neural network model, acoustic feature information corresponding to the text and alignment information in which each frame of the acoustic feature information is matched with each phoneme included in the text, identifying an utterance speed of the acoustic feature information based on the alignment information, identifying a reference utterance speed for each phoneme included in the acoustic feature information based on the text and the acoustic feature information, obtaining utterance speed adjustment information based on the utterance speed of the acoustic feature information and the reference utterance speed for each phoneme, and obtaining, based on the utterance speed adjustment information, speech data corresponding to the text by inputting the acoustic feature information into a second neural network model.
