Abstract

An electronic device is provided. The electronic device includes a processor and a memory electrically connected to the processor. The memory stores a super-clustered common acoustic data set and instructions to allow the processor to acquire at least one text, select information associated with a speech into which the acquired text is transformed, when the selected information is first information, select at least one of first paths, load elements of the super-clustered common acoustic data set based on the selected first paths, and generate a first acoustic signal based on the elements of the super-clustered common acoustic data set, and when the selected information is second information, select at least one of second paths, load elements of the super-clustered common acoustic data set based on the at least one second path, and generate a second acoustic signal based on the elements of the super-clustered common acoustic data set.
