Acknowledgements
Built on the work of others
Saywind is built on open models and open-source software. These are the credits and licences that ship with the app, in full.
SAYWIND ACKNOWLEDGEMENTS Saywind is made by Peiser Apcar Ltd. It is built on the work below, with thanks. Each item keeps its own licence, and nothing in Saywind's own terms limits the rights those licences give you. SPEECH MODELS Saywind downloads these models to your Mac the first time each is needed. They are not built into the app. Parakeet Ultra, by Moondream: a post-trained version of Parakeet TDT 0.6B v3. https://huggingface.co/moondream/parakeet-ultra Parakeet TDT 0.6B v3, by NVIDIA. https://huggingface.co/nvidia/parakeet-tdt-0.6b-v3 Parakeet TDT 0.6B v2, by NVIDIA. https://huggingface.co/nvidia/parakeet-tdt-0.6b-v2 Parakeet TDT-CTC 110M, by NVIDIA. Saywind uses it to spot the words in your dictionary. https://huggingface.co/nvidia/parakeet-tdt_ctc-110m All four are licensed under Creative Commons Attribution 4.0 International (CC BY 4.0): https://creativecommons.org/licenses/by/4.0/ Changes: each model was converted to Core ML by FluidInference. The conversions store some weights in compressed form (Parakeet Ultra's encoder, for example, uses 8-bit integers), and the 110M conversion keeps only the model's CTC output. Saywind uses these conversions as published: https://huggingface.co/FluidInference/parakeet-ultra-coreml https://huggingface.co/FluidInference/parakeet-tdt-0.6b-v3-coreml https://huggingface.co/FluidInference/parakeet-tdt-0.6b-v2-coreml https://huggingface.co/FluidInference/parakeet-ctc-110m-coreml The models are provided as they are, without warranties, as sections 5 and 6 of the CC BY 4.0 licence describe. SOFTWARE FluidAudio 0.17.7, by FluidInference. Apache License 2.0. https://github.com/FluidInference/FluidAudio Saywind compiles in the whole of FluidAudio, including parts it never uses, such as text-to-speech, speaker separation, and Japanese, Spanish and French text handling. FluidAudio contains the following third-party work. Licence texts follow at the end. fastcluster, by Daniel Müllner and Google Inc. BSD 2-clause licence. VBx speaker clustering, by BUT Speech@FIT. Apache License 2.0. https://github.com/BUTSpeechFIT/VBx misaki, by hexgrad. Apache License 2.0. FluidAudio ports parts of it to Swift, including misaki's versions of cutlet, by Paul O'Leary McCann (MIT), and Convert-Numbers-to-Japanese, by David Wilson (MIT). https://github.com/hexgrad/misaki https://github.com/polm/cutlet https://github.com/Greatdane/Convert-Numbers-to-Japanese kokoro-coreml, by laishere, and kokoro-coreml, by mattmireles. Both Apache License 2.0. FluidAudio's Kokoro text-to-speech code is derived from or draws on them; the notice for the second is reproduced below. https://github.com/laishere/kokoro-coreml https://github.com/mattmireles/kokoro-coreml Code adapted from or modelled on: NVIDIA NeMo, by NVIDIA. Apache License 2.0. https://github.com/NVIDIA/NeMo FunASR. MIT. https://github.com/modelscope/FunASR LocalVQE, by localai-org. Apache License 2.0. https://github.com/localai-org/LocalVQE Supertonic, by Supertone Inc. MIT. https://github.com/supertone-inc/supertonic Credited for completeness, although Saywind never downloads them: the data that FluidAudio's text-to-speech features would download, including the UniDic dictionary, by the UniDic Consortium (BSD licence), word lists from ipa-dict, by dohliam (MIT), and the CharsiuG2P model, by jzhu (MIT). FluidAudio's optional NeMo text-processing engine is left out of Saywind's build, so it is not included. ================================================================================ Apache License 2.0 Applies to FluidAudio, VBx (Copyright 2021-2024 BUT Speech@FIT), misaki, both kokoro-coreml projects, NVIDIA NeMo and LocalVQE. ================================================================================ Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.

Source: https://github.com/mattmireles/kokoro-coreml Source revision: a3f1ff27b1d8683efa9976704b46cb1d96da1a4b Model: https://huggingface.co/mattmireles/kokoro-coreml Model revision: 9183566f294ca3f31a63fd2767cf5848bfebfd50 Modifications by FluidInference: verify convolution and linear parameters against our checkpoint export, replace differing folded style-projection biases and inverse-STFT kernels, add provenance metadata, and integrate with our existing front end, masked decoder, and deterministic native source DSP. For the Mandarin variant, transfer all convolution/linear parameters, Snake activation scales and folded reciprocals from the separate v1.1-zh checkpoint. See generator-provenance.json beside generated models for every changed constant. fast_pipeline.py and the native source/STFT stage also draw architectural inspiration from the same project. The source excitation retains this toolkit's deterministic CoreMLSineGenV2 semantics. Retain this notice and mattmireles-LICENSE when distributing adapted artifacts.
