GrainSpeech model achieves high-quality speech synthesis with minimal parameters

Researchers have developed GrainSpeech, a novel compact speech synthesis model that significantly reduces parameter count while maintaining high quality. By optimizing encoder context and employing a Mel-specific gradient supervision technique, GrainSpeech achieves a 36.0% reduction in pitch prediction error and operates at 17.9x real-time generation speed on microcontrollers. This model, with only 264.8K parameters, rivals larger models in quality with a fraction of their size. AI

IMPACT Enables high-quality, real-time speech synthesis on resource-constrained devices like microcontrollers.

    GrainSpeech: Less Context, More Detail for Compact Speech Synthesis

    arXiv:2609.18856v1 Announce Type: cross Abstract: Compact acoustic models face a challenging quality-capacity trade-off. We investigate two factors in this regime: encoder context and Mel-spectrogram supervision. A receptive-field-scaling study shows that expanding self-attention…
