Brieflee speech and speaker model files: licence notice
Published 6 October 2026 at https://brieflee.ai/models/LICENSE.txt

The files under https://brieflee.ai/models/ are downloaded by the Brieflee
phone app and the Brieflee desktop app and run on your own device. They are of
two kinds, and the two kinds carry different terms.

1. Brieflee's own models

   The files whose names carry "brieflee" (for example
   ggml-small-brieflee-6-q8_0.bin and ggml-base-brieflee-2-q8_0.bin) are
   Brieflee's fine-tuned speech models. They were built from OpenAI's Whisper
   weights and trained further on publicly available recordings only, never
   on a customer's meeting. Copyright (c) Xtreme IT Services, trading as
   Brieflee. They are licensed to you, not sold, for use with your Brieflee
   account, the Brieflee apps and the Brieflee service, under the Terms of
   Service at https://brieflee.ai/terms. You may not copy them elsewhere,
   redistribute them, use them in another product, or extract, de-quantise or
   train from them. The MIT notice for the Whisper weights they are built from
   is reproduced below and continues to apply to that part.

2. Open-source models served under their own licences

   These files keep the licence their authors gave them. The Brieflee terms in
   part 1 do not apply to them and nothing in this notice narrows the rights
   those licences give you.

   - ggml-tiny-q5_1.bin, ggml-base-q5_1.bin, ggml-small-q5_1.bin,
     ggml-small-q8_0.bin: OpenAI's Whisper weights (MIT licence,
     Copyright (c) 2022 OpenAI), converted to the ggml file format with
     whisper.cpp (MIT licence, Copyright (c) The ggml authors).

   - pyannote-segmentation-3-0.onnx: pyannote speaker segmentation 3.0
     (MIT licence, Copyright (c) CNRS), as released in ONNX form by the
     sherpa-onnx project.

   - wespeaker-resnet34-lm-gm.onnx: the WeSpeaker ResNet34-LM speaker
     embedding model, trained on VoxCeleb by the WeSpeaker project and released
     under the Creative Commons Attribution 4.0 International licence
     (https://creativecommons.org/licenses/by/4.0/), as released in ONNX form
     by the sherpa-onnx project. Brieflee added one metadata entry
     (feature_normalize_type) and changed nothing else.
