New research suggests separate optimization for TTS model depth and refinement

A new research paper explores the trade-offs between model depth and refinement steps in masked-diffusion text-to-speech (TTS) models. The study found that while refinement steps significantly improve intelligibility, they are less effective at preserving speaker identity compared to increasing model depth. The research suggests that these two computational aspects target different bottlenecks and should be optimized separately, with additional findings indicating that the codec component of the TTS system plays a crucial role in the remaining identity deficit. AI

IMPACT This research suggests that optimizing text-to-speech models requires a nuanced approach, potentially leading to more natural and speaker-preserving voice synthesis technologies.

    Refinement Buys Intelligibility, Search Buys Identity: What Test-Time Compute Buys in Masked-Diffusion TTS

    arXiv:2610.03320v1 Announce Type: new Abstract: Diffusion language models for text-to-speech combine two forms of computation: model depth (parameters) and refinement steps (inference budget). We ask whether they scale equally across capabilities. We train 15 masked-diffusion cod…
