Expressive Speech Synthesis
A speech synthesis technology that achieves fine-grained emotional expression by controlling acoustic features such as pitch, speaking rate, and energy. It can incorporate Global Style Token (GST) or VAE mechanisms to enable smooth transitions within a continuous emotional space.
Timeline (last 90 days)
The development of emotional voice devices is not a linear optimization toward ever-higher emotional expressiveness, but rather requires finding a balance between naturalness and controllability.
For people who have lost their voice, emotional voice systems must infer emotional intent from residual muscle signals, facial movements, or text input in the absence of real-time acoustic input, placing far higher demands on latency and accuracy than typical TTS scenarios.
