Emotional TTS can be dramatically enhanced by personalizing expression based on individual and cultural perception, leading to more authentic interactions.
Injecting fine-grained non-verbal cues into TTS can almost perfectly convey sadness (98.3%) and significantly boosts expressiveness overall, despite slight naturalness trade-offs.
A single architecture now unlocks both fast GAN-based and diffusion-based neural vocoders, achieving state-of-the-art speed and quality while drastically reducing training time.
