Descrição da fonte
First-party CoreML export of Supertonic-3's four non-autoregressive flow-matching graphs, for
on-device iOS / Apple Neural Engine. Built by our own pipeline (speech-models/stmodels): weights
lifted from the ONNX
initializers → PyTorch → (, FP32, iOS18+).

Text/duration use fixed T=128 (relpos attention has T-dependent pad widths — pad/segment text to
128); vocoder + vector-estimator use a dynamic latent-length RangeDim. The host runs the flow-matching
ODE loop (vector_estimator ×total_steps) — the graphs contain no control flow. Assets to drive them:
tts.json, unicode_indexer.json (G2P-free tokenizer table), voice_styles/*.json.
FP32 = parity reference. For ANE residency, use the mixed-precision
Supertonic-3-CoreML-FP16— vocoder + duration FP16, text-encoder + vector-estimator FP32; measured transparent at 47–51 dB mag-STFT SNR.
