# Third-party notices

Anuvani-Diarization's code is licensed under MIT OR Apache-2.0 (`LICENSE-MIT`, `LICENSE-APACHE`). It contains, ports
or links work by others, listed here with their licences. The model weights have their own licences, set by the
models they derive from (see the model card): the segmentation network is a fine-tuned derivative of
`BUT-FIT/diarizen-wavlm-large-s80-md-v2` and is CC BY-NC 4.0 (non-commercial); the PLDA model (BUT Speech@FIT) and
the speaker-embedding network (`pyannote/wespeaker-voxceleb-resnet34-LM`) are CC BY 4.0.

## Code copied or adapted into this project

| Upstream | Licence | Where | Licence text |
|---|---|---|---|
| DiariZen (BUT Speech@FIT), commit 844f555 | MIT | the segmentation network's code, verbatim (`python/anuvani_diar/nn/seg/`; also the frozen release's `hf_port_poc/anuvani_diar_net/`); its VBx and clustering set-up, ported to Rust (`crates/diar-core`) | `LICENSES/third_party/DiariZen-MIT.txt` |
| torchaudio 2.1.1 (Facebook, Inc.) | BSD-2-Clause | `kaldi.py` (fbank) and `resample.py`, verbatim; the wav2vec2 building blocks inside DiariZen's code | `LICENSES/third_party/torchaudio-BSD-2-Clause.txt` |
| pyannote.audio 3.1.1, DiariZen's fork (CNRS) | MIT | the voiceprint network's fbank, forward and statistics pooling (`voiceprint.py`); window reconstruction and masks, ported to Rust | `LICENSES/third_party/pyannote-audio-MIT.txt` |
| WeSpeaker (Shuai Wang), via pyannote.audio | Apache-2.0 | the voiceprint network's ResNet34 (`voiceprint.py`) | `LICENSES/third_party/Apache-2.0.txt` |
| VBx (BUT Speech@FIT), via DiariZen's `diarizen/clustering/VBx.py` | Apache-2.0 | variational Bayes clustering, ported to Rust (`crates/diar-core/src/vbx.rs`) | `LICENSES/third_party/Apache-2.0.txt` |
| SciPy 1.15.3 (SciPy Developers) | BSD-3-Clause | centroid-linkage AHC and pairwise distances, reimplemented in Rust to give SciPy's exact results | `LICENSES/third_party/scipy-LICENSE.txt` |
| NumPy 1.26.4 (NumPy Developers) | BSD-3-Clause | numerical behaviour reproduced in Rust; its OpenBLAS build is bundled (below) | `LICENSES/third_party/numpy-LICENSE.txt` |
| python-soundfile 0.14.0 (Bastian Bechtold) | BSD-3-Clause | the sequence of libsndfile calls `sf.read` makes, reproduced in Rust (`crates/diar-audio`) | `LICENSES/third_party/soundfile-LICENSE.txt` |

## Native libraries bundled in the wheel

Copied unchanged from the numpy 1.26.4 and soundfile 0.14.0 wheels, each checked by sha256 when it loads; their
licence texts are in the wheel (`anuvani_diar/_libs/LICENSES/`, index in its README.txt):

| Library | Licence |
|---|---|
| OpenBLAS 0.3.23.dev (numpy 1.26.4's build) | BSD-3-Clause |
| libgfortran 5 | GPL-3.0 with the GCC Runtime Library Exception 3.1 |
| libquadmath 0 | LGPL-2.1-or-later |
| libsndfile 1.2.2, with FLAC 1.4.3, Ogg 1.3, Vorbis 1.3.7, Opus 1.4, mpg123 1.32.3, LAME 3.100 | LGPL-2.1-or-later (libsndfile, mpg123, LAME); BSD-3-Clause (FLAC, Ogg, Vorbis, Opus) |

libsndfile is LGPL: `ANUVANI_DIAR_SNDFILE` (with `ANUVANI_DIAR_SNDFILE_UNCHECKED=1`) runs the engine with another
build of it (`docs/WHEEL.md`). The source of the LGPL libraries (libsndfile with its codecs and the script that built
it; libquadmath, as the GCC source package it was built from) is in the model repository's `third_party_sources/`,
whose README traces each binary to its source.

## Container images the serving kit builds

`triton_inference/` builds two images on the user's machine; they are not distributed here. The Triton image starts
from `nvcr.io/nvidia/tritonserver:24.10-py3` (NVIDIA Deep Learning Container License) and installs PyTorch and
torchaudio 2.1.1 (BSD-3-Clause and BSD-2-Clause) and NVIDIA's cuBLAS and NVRTC wheels (NVIDIA proprietary licence);
the service image starts from `ubuntu:22.04` and installs FastAPI and Pydantic (MIT), Starlette and Uvicorn
(BSD-3-Clause) and python-multipart (Apache-2.0) (`triton_inference/service/requirements.txt`).
