DriftTTS: New Text-to-Speech Model Achieves High Quality Without Distillation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed DriftTTS, a novel few-step text-to-speech model that achieves competitive synthesis quality without relying on distillation from pretrained teachers or adversarial discrimination. The model utilizes a distribution-matching drift objective in a mel-domain feature space, trained using on-policy rollout. On the LJSpeech dataset, DriftTTS demonstrated strong performance with low MCD and WER, and in blind listening tests, it achieved a MOS score comparable to ground truth and superior to Matcha-TTS. AI

IMPACT This research offers a new approach to few-step TTS synthesis, potentially reducing computational requirements and complexity in training.

    DriftTTS: Few-Step Text-to-Speech Without Distillation via Distribution-Matching Drift

    arXiv:2610.03390v1 Announce Type: cross Abstract: Few-step neural text-to-speech models often rely on short- ened diffusion or flow-matching schedules, or on distillation from pretrained multi-step teachers. To avoid these depen- dencies, we present DriftTTS, a few-step mel-spect…
