Introduction of Supertonic-3-CoreML

Model Details of Supertonic-3-CoreML

SupertonicTTS-3 — CoreML (.mlpackage, iOS)

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 Supertone/supertonic-3 ONNX initializers → PyTorch nn.Module coremltools ( mlprogram , FP32, iOS18+).

Graphs & parity (FP32, vs ONNX Runtime)
Module mlpackage parity max|Δ|
Duration predictor DurationPredictor.mlpackage 7.2e-06 ✓
Vector estimator (ODE denoiser) VectorEstimator.mlpackage 2.5e-03 ✓
Vocoder Vocoder.mlpackage 3.0e-04 ✓
Text encoder TextEncoder.mlpackage mean 2.5e-04 (max 2.5e-2 at isolated positions)

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.
