Suzune S1: 80M Non-Autoregressive Speech Foundation
Acoustic diffusion architecture unifying 12-layer PL-BERT context, continuous AdaLN prosody, and fast iSTFTNet vocoding.
Engineered for real-time edge and cloud deployment. Suzune S1 eliminates the serial latency bottlenecks and stochastic hallucinations of autoregressive audio generation by predicting multi-band STFT magnitude and phase components directly. Achieves 24kHz studio HD audio at RTF 0.018 on GPU and RTF 0.087 on CPU cores with constant ~320MB VRAM.
