Abstract: Disclosed is an electronic device and a control method therefor. The electronic device according to an embodiment includes: memory storing at least one instruction and at least one processor, comprising processing circuitry, individually and/or collectively, configured to execute the at least one instruction, and to: identify a target pitch shift value for shifting a pitch of voice data, divide the identified target pitch shift value into a first pitch shift value and a second pitch shift value, identify a pitch shift embedding value based on the first pitch shift value, obtain second voice data by updating a feature of a pitch of first voice data based on the second pitch shift value, identify a pitch embedding value based on a pitch of the obtained second voice data, and obtain third voice data to which the pitch of the first voice data is shifted based on the pitch shift embedding value and the pitch embedding value.

Abstract: An example electronic device and an example control method thereof are provided. The example electronic device may include: a memory configured to store information about a plurality of intonation templates, which are obtained by training an intonation template generator based on a plurality of voice signals and represent intonations of the plurality of voice signals; and a processor configured to, when a voice signal is received, obtain information about a user’s intention corresponding to the voice signal, obtain first text to respond to the voice signal, based on the voice signal and the information about the user’s intention, identify an intonation template corresponding to the first text based on the information about the plurality of intonation templates by inputting information about the first text to an intonation classifier, obtain intonation information corresponding to the identified intonation template by inputting information about the identified intonation template to the intonation encoder, and obtain an output voice signal corresponding to text by inputting the first text and the intonation information to a voice synthesis module.
