Abstract: A method of generating a residual signal performed by an encoder includes identifying an input signal including an audio sample, generating a first residual signal from the input signal using linear predictive coding (LPC), generating a second residual signal having a less information amount than the first residual signal by transforming the first residual signal, transforming the second residual signal into a frequency domain, and generating a third residual signal having a less information amount than the second residual signal from the transformed second residual signal using frequency-domain prediction (FDP) coding.

Abstract: An emotional speech generating method and apparatus capable of adjusting an emotional intensity is disclosed. The emotional speech generating method includes generating emotion groups by grouping weight vectors representing a same emotion into a same emotion group, determining an internal distance between weight vectors included in a same emotion group, determining an external distance between weight vectors included in a same emotion group and weight vectors included in another emotion group, determining a representative weight vector of each of the emotion groups based on the internal distance and the external distance, generating a style embedding by applying the representative weight vector of each of the emotion groups to a style token including prosodic information for expressing an emotion, and generating an emotional speech expressing the emotion using the style embedding.
