16. Piper TTS and the components inside its release archive
| Repository | github.com/rhasspy/piper — release 2023.11.14-2 |
| License | MIT License (Piper itself) |
| Used for | On-device text-to-speech (Read Aloud, and AI voice output in NotesXML) on Windows and Linux. Voice models are downloaded on demand and verified against pinned SHA-256 digests. Not present on Android, which uses the platform speech engine. |
| Shipped as | The official, unmodified release archives, pinned by SHA-256: piper_linux_x86_64.tar.gz (a50cb45f…225992) and piper_windows_amd64.zip (f3c58906…1efcea). Both were opened and listed on 14 September 2026; the components below are what they contain. |
The Piper release archive contains more than the Piper engine. NotesXML and NotesXML Local redistribute the whole archive unmodified, so every component in it is credited here, and one of them — eSpeak NG — is licensed under the GNU GPL, which carries obligations we meet below.
| piper-phonemize 1.2.0 | github.com/rhasspy/piper-phonemize — MIT License. Copyright © 2023 Michael Hansen. Text-to-phoneme conversion for the Piper engine (libpiper_phonemize / piper_phonemize.dll). |
| eSpeak NG | github.com/espeak-ng/espeak-ng — GNU General Public License v3.0 or later (full licence text). Copyright © 2005–2014 Jonathan Duddington (eSpeak); © 2015–2024 Reece H. Dunn and the eSpeak NG contributors. The 1.52 development snapshot bundled by Piper (libespeak-ng.so.1.52.0.1 / espeak-ng.dll and the espeak-ng-data directory). Used by Piper solely for text phonemization. |
| ONNX Runtime 1.14.1 | github.com/microsoft/onnxruntime (Microsoft) — MIT License. The inference engine that runs the Piper voice models. |
| Tashkeel model | github.com/mush42/libtashkeel — MIT License. Copyright © 2023 Musharraf. An Arabic diacritization model shipped inside piper-phonemize as libtashkeel_model.ort; NotesXML offers no Arabic voice, so it ships unused. |
Your rights under the GPL, and the corresponding source
eSpeak NG is free software: you may use, study, modify and redistribute it under the terms of the GNU GPL version 3 or, at your option, any later version. NotesXML does not modify eSpeak NG, does not link against it and does not call it; it is used only by the separate piper program, which NotesXML runs as an independent process. The GPL applies to eSpeak NG and to the Piper binaries that link it; it does not extend to NotesXML’s own code.
Corresponding source (GPL v3 §6). The complete corresponding source code for the components inside the Piper archive is offered from this page, the same place NotesXML itself is downloaded from:
A note on the eSpeak NG revision: piper-phonemize’s 1.2.0 build script fetched the rhasspy fork’s master branch at build time rather than a fixed commit. The archive above is that fork at the commit the project subsequently pinned, which is the closest identifiable corresponding source for the November 2023 binaries; the fork’s history is public if you wish to compare revisions.
Written offer. In addition to the downloads above, IWV Digital Solutions LLC will supply the corresponding source for the eSpeak NG, piper-phonemize and Piper binaries it distributes, on request, for no more than the cost of physically performing the distribution, for a period of at least three years from the date of distribution and for as long as support is offered for the version of NotesXML in question. Write to legal@iwvdigitalsolutions.com.
The same notices, including the full GPL text, ship inside every NotesXML and NotesXML Local desktop package as THIRD_PARTY_NOTICES.txt (Help → About → Open Source Licenses).
17. Microsoft Visual C++ Runtime (app-local)
| Provider | Microsoft Corporation |
| Components | vcruntime140.dll, vcruntime140_1.dll, msvcp140.dll (from the Microsoft Visual C++ Redistributable, deployed app-locally beside each bundled engine) |
| License | Redistributed under the Microsoft Visual Studio license terms for REDIST-listed files |
| Used for | C/C++ runtime support for the bundled Windows inference engines (llama-server, whisper, Piper), so AI, dictation and read-aloud features work on every Windows PC without requiring a separate Visual C++ Redistributable installation (added in Beta 5.142.58) |
AI Models
NotesXML downloads AI models on demand from Hugging Face. Each model has its own license:
| Model | Provider | License |
|---|
| LFM2.5 VL 1.6B (vision-capable) — free tier, recommended default | Liquid AI | LFM Open License v1.0 — see the note below |
| Ministral 3 3B Instruct (vision-capable) — free tier | Mistral AI | Apache License 2.0 |
| Gemma 4 E2B (vision-capable) | Google DeepMind | Apache License 2.0 |
| LFM2.5 VL 3B (vision-capable) | Liquid AI | LFM Open License v1.0 |
| Gemma 4 E4B (vision-capable) | Google DeepMind | Apache License 2.0 |
| Ministral 3 8B Instruct (vision-capable) | Mistral AI | Apache License 2.0 |
| Mellum2 12B-A2.5B Instruct (MoE; coding) | JetBrains s.r.o. | Apache License 2.0 |
| Gemma 4 12B (vision-capable) | Google DeepMind | Apache License 2.0 |
| Ministral 3 14B Instruct (vision-capable) | Mistral AI | Apache License 2.0 |
| GPT-OSS 20B (MoE) — desktop only | OpenAI | Apache License 2.0 |
| Devstral Small 2 24B (coding; vision-capable) | Mistral AI | Apache License 2.0 |
| Gemma 4 26B-A4B MoE (vision-capable) — desktop only | Google DeepMind | Apache License 2.0 |
| Muse Glimmer 30B (vision-capable) — desktop only | Meta Superintelligence Labs | Apache License 2.0 |
| Nemotron 3.5 Lightning 30B-A3B (MoE) — desktop only | NVIDIA Corporation | OpenMDW License Agreement v1.1 |
| Gemma 4 31B (Dense) (vision-capable) — desktop only | Google DeepMind | Apache License 2.0 |
| Laguna XS 2.1 33B-A3B (MoE; coding) — desktop only | Poolside AI | OpenMDW License Agreement v1.1 |
AI models are not bundled with NotesXML. They are downloaded separately at the user's request and stored on the user's device. Users are responsible for compliance with each model provider's license terms (links to provider terms are available on each model's Hugging Face model card).
LFM2.5 VL licence — please read if you use NotesXML at work. LFM2.5 VL 1.6B is the recommended default model and is available on the free tier. It is published by Liquid AI under the LFM Open License v1.0, which permits personal use freely, and permits commercial use only by organisations with annual revenue under US $10 million. If your organisation is above that threshold, you will need a separate licence from Liquid AI to use this model commercially, or you can select any other model in the catalog — Ministral 3 3B is also on the free tier, is also vision-capable, and is Apache 2.0 licensed with no revenue condition. NotesXML shows this condition on the model's entry in the AI Models window before you download it. This licence applies to the model only; it places no conditions on NotesXML itself or on the notes you create.
Two models use the OpenMDW License. Nemotron 3.5 Lightning 30B-A3B (NVIDIA) and Laguna XS 2.1 33B-A3B (Poolside AI) are published under the OpenMDW License Agreement, version 1.1 rather than Apache 2.0. OpenMDW is a permissive open model licence covering weights, code and documentation together; it imposes no revenue condition. Both are desktop-only models and neither is on the free tier.
Models retired from the catalog. Llama 3.2 1B Instruct was removed in NotesXML 5.181.4; Llama 3.2 3B Instruct and Phi-4 Mini were removed in the 2026-08-12 catalog revision; LFM2 VL 3B was replaced by its successor LFM2.5 VL 3B in NotesXML 5.188.0. Gemma 4 E2B was removed in 5.181.4 and reinstated in 5.198.33; it appears in the table above. If you downloaded a retired model under an earlier version it remains on your device and continues to work, and it remains governed by the licence listed for its provider.
