Cross-speaker Style Transfer with Prosody Bottleneck in Neural Speech Synthesis

Understand

Cross-speaker style transfer is crucial to the applications of multi-style and expressive speech synthesis at scale.

• It does not require the target speakers to be experts in expressing all styles and to collect corresponding recordings for model training.
• However, the performances of existing style transfer methods are still far behind real application needs.
• The root causes are mainly twofold.
