================================================================================ KIMITALK LOCAL SPEECH HELPER — OPEN-SOURCE NOTICE & ACKNOWLEDGEMENTS ================================================================================ Component: LocalSpeechHelper.app (Speech Output Add-On for KimiTalk) Version: See helper-metadata.json (helper_version) Vendor: KIMIKON e.U., Vienna, Austria Mirror: https://updates.kimikon.cc/kimitalk/speech-helper//NOTICE.txt Date: 2026-05-26 — license hygiene pass Copyright (c) 2024-2026 KIMIKON e.U., Vienna, Austria. This Helper bundles open-source software and consumes local model caches prepared by KimiTalk. In the ordinary release path, KimiTalk prepares those caches from KIMIKON's `models.kimikon.cc` mirror, verifies SHA-256 checksums, then starts the Helper in offline runtime mode. Upstream repository names remain documented below for provenance and license attribution. Full license texts live in the adjacent LICENSES/ directory. This file applies ONLY to the LocalSpeechHelper.app DMG. The main KimiTalk.app bundle has its own NOTICE / Acknowledgements view inside the app. ================================================================================ PART 1 — BUNDLED SOFTWARE IN LocalSpeechHelper.app ================================================================================ The Helper is a Python-based subprocess launched by KimiTalk. The following components are bundled (statically copied) into the .app: -------------------------------------------------------------------------------- 1.1 Python Software Foundation Runtime PSF License v2 -------------------------------------------------------------------------------- Copyright (c) 2001-2026 Python Software Foundation. All Rights Reserved. Python is licensed under the PSF License v2, with additional licenses for bundled components (OpenSSL, zlib, libffi, expat). See LICENSES/PSF-Python.txt for the full license text stack. -------------------------------------------------------------------------------- 1.2 PyTorch (torch) BSD 3-Clause -------------------------------------------------------------------------------- Copyright (c) 2016-present, Meta Platforms, Inc. and affiliates. Additional copyrights: Idiap Research Institute, DeepMind, NEC Labs, NYU, Google, Kakao Brain, Cruise LLC, Tri Dao, Arm Limited, and PyTorch contributors. The bundled PyTorch wheel includes libiomp5 (Intel OpenMP runtime) under the Apache License 2.0 with LLVM Exception. See LICENSES/BSD-3-Clause.txt and LICENSES/Apache-2.0-FULL.txt. -------------------------------------------------------------------------------- 1.3 torchaudio BSD 2-Clause -------------------------------------------------------------------------------- Copyright (c) 2017 Facebook, Inc. See LICENSES/BSD-2-Clause.txt. -------------------------------------------------------------------------------- 1.4 Additional BSD/Apache Python dependencies -------------------------------------------------------------------------------- - numpy — BSD 3-Clause - scipy — BSD 3-Clause - soundfile — BSD 3-Clause (Python wrapper) - huggingface-hub — Apache License 2.0 - transformers — Apache License 2.0 - tokenizers — Apache License 2.0 - safetensors — Apache License 2.0 - mlx (Apple) — MIT License - mlx-lm — MIT License - librosa — ISC License (compatible with BSD/Apache) Full text references in LICENSES/Apache-2.0-FULL.txt, BSD-2-Clause.txt, BSD-3-Clause.txt. -------------------------------------------------------------------------------- 1.5 libsndfile LGPL-2.1+ -------------------------------------------------------------------------------- Copyright (c) 1999-2024 Erik de Castro Lopo and the libsndfile contributors. libsndfile is the native C library underlying the python-soundfile module. It is dynamically loaded by the Python soundfile wheel via CFFI. LICENSE: GNU Lesser General Public License, version 2.1 or later. See LICENSES/LGPL-2.1-FULL.txt for the full license text. SOURCE-OFFER (LGPL-2.1 § 6): KIMIKON e.U. provides, upon written request to legal@kimikon.cc, the unmodified libsndfile source corresponding to the bundled version, for a fee not exceeding the cost of physical distribution. Please include the LocalSpeechHelper version (visible in the helper-metadata.json / KimiTalk About dialog) so we can ship the exact matching source. -------------------------------------------------------------------------------- 1.6 AudioSeal (Meta, facebookresearch/audioseal) MIT License -------------------------------------------------------------------------------- Copyright (c) 2024 Meta Platforms, Inc. and affiliates. STATUS: ACTIVE (Phase 19, Helper v0.6.0). AudioSeal is bundled with this Helper as ONNX models in Resources/Models/ (generator + detector, 16-bit payload). The Helper invokes AudioSeal embed and detect via the provenance.* NDJSON subcommands. C2PA belongs to this Local Speech Helper: the Helper bundles c2pa-python and the native c2pa-rs library shipped inside that wheel, and invokes them through the same provenance channel. See sections 1.7 below, LICENSES/Apache-2.0-FULL.txt, and LICENSES/c2pa-python-MIT.txt. Phase 19 migrated the heavy provenance runtime (libc2pa_c.dylib and AudioSeal ONNX models) out of the KimiTalk main app into this Helper, so the main DMG stays small. Helper-backed AI-audio export requires this provenance runtime and fails closed if mandatory AudioSeal/C2PA provenance cannot be created. See LICENSES/AudioSeal-MIT.txt. -------------------------------------------------------------------------------- 1.7 C2PA / c2pa-python / c2pa-rs Apache 2.0 OR MIT -------------------------------------------------------------------------------- c2pa-python is the official Python binding for the C2PA Content Authenticity SDK. It wraps and bundles the native c2pa-rs library used for C2PA signing and verification. STATUS: ACTIVE (Helper provenance runtime). KimiTalk.app does not link or bundle libc2pa. Helper-backed AI-audio export uses this Helper process for C2PA manifests; export fails closed if mandatory C2PA provenance cannot be created. See LICENSES/Apache-2.0-FULL.txt and LICENSES/c2pa-python-MIT.txt. ================================================================================ PART 2 — RUNTIME-PREPARED MODEL WEIGHTS (KIMIKON/R2 mirror, not bundled in DMG) ================================================================================ Model weights are NOT bundled in this DMG. For release models, KimiTalk prepares them into the local cache from the KIMIKON/R2 mirror at `models.kimikon.cc` and verifies every manifest/file with SHA-256 before the Helper loads them. Licenses and required notices are reproduced here because KIMIKON e.U. orchestrates model preparation and documents the upstream model sources. -------------------------------------------------------------------------------- 2.1 hexgrad / Kokoro-82M Apache License 2.0 -------------------------------------------------------------------------------- Copyright (c) 2024 hexgrad and Kokoro contributors.
