Abstract: The disclosure relates to an electronic device and a control method thereof. The electronic device includes a memory, and a processor configured to: obtain first feature data for estimating a waveform by inputting acoustic data of a first quality to a first encoder model; and obtain waveform data of a second quality that is a higher quality than the first quality by inputting the first feature data to a decoder model to.

Abstract: A method, performed by an electronic device, of generating a speech signal corresponding to at least one text is provided. The method includes obtaining feature information with respect to a first sample included in the speech signal, based on the at least one text, obtaining condition information related to a condition under which a bunching operation, in which one or more sample values included in the speech signal are obtained, is performed, based on the feature information, configuring one or more bunching blocks for performing the bunching operation, based on the condition information, obtaining the one or more sample values based on the feature information with respect to the first sample by using the one or more bunching blocks, and generating the speech signal based on the obtained one or more sample values.
