EmoRES-TTS: Residual-Enhanced Vector Steering for Emotional Speech Generation
Emotion-conditioned text-to-speech (TTS) models may fail to express the requested emotion reliably, and improving controllability by additional training is costly in both computation and emotion-labeled speech training data. We therefore study vector steering, a training-free approach that modifies the internal represe...
