Kokoro-82M text-to-speech (ONNX, 55 voices)

Browser-ready import artifacts for text-to-speech, produced by SkillSafe's reproducible converter (models/ in skillsafe.ai) from a pinned upstream source. Every byte here is derivable from that source plus the recipe below; nothing was edited by hand.

registry files are parameter files served from models.skillsafe.ai once vetted; bundle files ship inside an app; registry-shared is a runtime library reused by every model of the same architecture.

Verification

Imported as published upstream (no conversion). Each file is pinned by SHA-256 to its source; every ONNX file passed onnx.checker and a CPU smoke run under onnxruntime with zero-filled inputs at the declared shapes:

file	inputs	outputs	ms
onnx/model_fp16.onnx	input_ids[1, 16], style[1, 256], speed[1]	waveform[1, 16800]	103.0
onnx/model_quantized.onnx	input_ids[1, 16], style[1, 256], speed[1]	waveform[1, 17400]	275.9

Use in the browser

import * as ort from "onnxruntime-web";
const session = await ort.InferenceSession.create("https://huggingface.co/skillsafe-ai/kokoro-82m/resolve/main/onnx/model_fp16.onnx", { executionProviders: ["webgpu", "wasm"] });

Contract (onnx/model_fp16.onnx): input input_ids int64 [1, 'sequence_length'], style float32 [1, 256], speed float32 [1] → output waveform float32 [1, 'num_samples']. Opset 20.
