Researchers have developed a new text-to-speech system called OscillaTTS that improves the modeling of sharp prosodic transitions and rapid pitch variations in expressive speech. This system introduces an adaptive oscillatory nonlinearity, which allows for controllable periodic modulation while maintaining signal stability. Experiments on the LJSpeech and Emotional Speech Dataset demonstrated consistent improvements in objective and subjective evaluations, indicating better modeling of expressive prosodic dynamics compared to existing methods that use static nonlinearities like the Snake activation function.
