Target-speaker adaptation in text-to-speech synthesis: a comparison of efficient fine-tuning and zero-shot methods

It is shown that fine-tuning a non-autoregressive architecture, such as ForwardTacotron, achieves speaker-adaptation quality comparable to zero-shot methods, with lower computational complexity but a lower mean opinion score.

Adapting Diffusion-Based Music Synthesis to Speech and Singing Voice Conversion

This work extends musical note-based conditioning to include phonetic posteriorgrams and pitch contours, and reinterpret timbre conditioning as speaker or singer identity via feature-wise linear modulation, and demonstrates that off-the-shelf feature extractors provide effective conditioning signals, enabling large-sca...
