New method creates compact Hindi TTS model via staged depth-pruning distillation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a method to create a compact Hindi text-to-speech (TTS) model by distilling a larger flow-matching teacher model, IndicF5. This process involves gradually pruning the depth of the transformer blocks while retaining other parameters, and re-fine-tuning at each stage. The resulting smaller models, down to 131 million parameters, achieve a low word-error rate on unseen sentences and can run in real-time on a 6GB laptop GPU. The study also identified and provided a fix for feature and library parity failures that can silently degrade audio quality. AI

IMPACT This research offers a practical recipe for developing efficient TTS models for specific languages, potentially lowering hardware requirements for real-time speech synthesis.

    Staged Depth-Pruning Distillation of a Flow-Matching Text-to-Speech Teacher: A Compact Hindi Speech Synthesizer

    arXiv:2607.18662v1 Announce Type: cross Abstract: We present a practical recipe for building a compact Hindi text-to-speech (TTS) model by distilling a large flow-matching teacher (IndicF5, 337M-parameter DiT) under a severe data budget (~17.6 hours). Training a small model from …
