Voicebox and Tacotron2 Zero-Shot Speech Synthesis Quality at Scale on VCTK

This report synthesises findings from 5 peer-reviewed papers addressing the following research question: How does the zero-shot speech synthesis quality (measured by MUSHRA scores) of FlashSpeech scale with larger model sizes compared to autoregressive models like Tacotron2 on the VCTK benchmark. 7 claims were extracted from source literature; 7 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 9.2/10. This report is a machine-generated literature synthesis and does not constitute original research.
