11. A computing device including a memory holding instructions executable by a processor to: generate an emotionally neutral representation of a script, the emotionally neutral representation comprising a neutral duration associated with each of a plurality of phonemes; and apply a duration adjustment factor to each neutral duration to generate a transformed duration sequence, the duration adjustment factor being dependent on an emotion type and a linguistic-contextual identity of the corresponding phoneme; generate a neutral fundamental frequency (F 0 ) prediction and a neutral spectrum prediction for each adjusted duration of the transformed duration sequence; and apply an F 0 adjustment factor to each neutral F 0 prediction and a spectrum adjustment factor to each neutral spectrum prediction to generate a transformed representation, each of the F 0 adjustment factor and the spectrum adjustment factor being dependent on the emotion type and the linguistic-contextual identity of the corresponding phoneme.

The device of claim 11 , the memory further holding instructions executable by the processor to: build a phoneme sequence based on a text script; modify the built phoneme sequence to generate a linguistic-contextual feature sequence based on extracted contextual features of the text script; wherein the plurality of phonemes of the neutral duration prediction block corresponds to the linguistic-contextual feature sequence.
