# QLA Voice – Third-Party Notices QLA Voice (the Chrome/Edge extension and the Excel add-in) includes the third-party software listed below. These notices must accompany every distribution: the store package, the hosted add-in files and the IT package. Texts marked **verbatim** were copied from each component's official source on 1 October 2026 (URL given). This file is the source of `THIRD-PARTY-NOTICES.txt`, which ships with both products (`npm run notices`). The speech model's training data isn't publicly documented (see below). ## Modification notice (Apache-2.0 §4(b)) `vendor/vosk.js` in the **browser extension** is a modified copy of vosk-browser 0.0.8's `dist/vosk.js`. QLA Voice's build (`scripts/build-extension.js`) changes its embedded web worker so that: - the speech model is kept in memory instead of IndexedDB; - the model URL is used as an absolute URL. The Excel add-in ships the file unmodified. The speech model `vosk-model-small-en-us-0.15` is redistributed **repackaged**. It was downloaded as a zip from alphacephei.com and re-archived as `models/vosk-model-small-en-us-0.15.tar.gz`, with its top folder renamed `model`. The model files themselves are unchanged. ## Summary | Component | Version | Licence | Ships in | |---|---|---|---| | vosk-browser (with Vosk API, Kaldi, OpenFst, CLAPACK/clapack-wasm, zlib, libarchive, Emscripten, musl; see its NOTICE) | 0.0.8 | Apache-2.0, plus the component licences in its NOTICE | Extension, add-in | | libarchive (inside the WebAssembly) | 3.5.1 | BSD-2-Clause; compress filter BSD-3-Clause (UC Regents) | Extension, add-in | | libf2c (inside the WebAssembly, via clapack-wasm) | – | AT&T / Lucent / Bellcore permissive notice | Extension, add-in | | libc++ / libc++abi (inside the WebAssembly) | – | Apache-2.0 WITH LLVM-exception (no notice required for compiled binaries) | Extension, add-in | | uuid | 9.0.0 | MIT | Extension, add-in | | JavaScript MD5 (blueimp, inside uuid) | – | MIT | Extension, add-in | | JavaScript MD5 (Paul Johnston, basis of the above) | 2.2 | BSD-3-Clause + RSA MD5 identification | Extension, add-in | | SHA-1 (adapted from Chris Veness, inside uuid) | – | MIT | Extension, add-in | | tslib (inside vosk.js) | – | 0BSD (no conditions) | Extension, add-in | | Speech model vosk-model-small-en-us-0.15 | 0.15 | Apache-2.0, as listed in the licence column of https://alphacephei.com/vosk/models; the training data used to build it isn't publicly documented (see below) | Extension, add-in | | Office.js | – | Microsoft terms; loaded from Microsoft's CDN, **not redistributed** | Add-in (by reference) | --- ## vosk-browser NOTICE (verbatim) Source: https://raw.githubusercontent.com/ccoreilly/vosk-browser/v0.0.8/NOTICE (fetched 2026-10-01; identical to master; the npm package doesn't include it). - The NOTICE's OpenFst section reproduces the OpenFst COPYING it was written for (v1.2.7 era); the WebAssembly contains OpenFst 1.8.0, also Apache-2.0. - Emscripten is dual-licensed MIT OR University of Illinois/NCSA; QLA Voice relies on the MIT option. ``` Vosk-Browser Copyright 2020-2022 Ciaran O'Reilly The Initial Developer of the the WASM bindings (https://github.com/dtreskunov/tiny-kaldi) for the VOSK API is Denis Treskunov (https://github.com/dtreskunov).

Each individual file in this distribution should have a clear copyright/licensing statement at the beginning of the file. If any do not, please let me know and I will rectify it. The following is intended to summarize the copyright status of the individual files; the actual statements in the files are controlling. * Except as listed below, all C sources (including .c and .h files) and documentation files are subject to the copyright notice reproduced at the bottom of this file. * The following source files are also subject in whole or in part to a 3-clause UC Regents copyright; please read the individual source files for details: libarchive/archive_read_support_filter_compress.c libarchive/archive_write_add_filter_compress.c libarchive/mtree.5 * The following source files are in the public domain: libarchive/archive_getdate.c * The following source files are triple-licensed with the ability to choose from CC0 1.0 Universal, OpenSSL or Apache 2.0 licenses: libarchive/archive_blake2.h libarchive/archive_blake2_impl.h libarchive/archive_blake2s_ref.c libarchive/archive_blake2sp_ref.c * The build files---including Makefiles, configure scripts, and auxiliary scripts used as part of the compile process---have widely varying licensing terms. Please check individual files before distributing them to see if those restrictions apply to you. I intend for all new source code to use the license below and hope over time to replace code with other licenses with new implementations that do use the license below. The varying licensing of the build scripts seems to be an unavoidable mess. Copyright (c) 2003-2018 All rights reserved.
