+LICENCE FLAG (not a blocker): eSpeak NG is GPL-3.0-or-later.
+
+When MISAKI_G2P_ESPEAK is ON and libespeak-ng is found, misaki_g2p links
+eSpeak NG 1.52.0 (https://github.com/espeak-ng/espeak-ng, tarball sha256
+bb4338102ff3b49a81423da8a1a158b420124b055b60fa76cfb4b18677130a23) and reads its
+English data (phontab, phonindex, phondata, intonations, en_dict, lang/gmw/en,
+lang/gmw/en-US). A binary that links libespeak-ng is a combined work under the
+GPL-3.0-or-later: distributing it requires the corresponding source and the GPL
+terms for the whole work. eSpeak NG is used only for words outside misaki's
+lexicon, exactly as misaki's EspeakFallback did when Paradee's training data
+was made.
+
+Built with MISAKI_G2P_ESPEAK=OFF (or without libespeak-ng present), no GPL code
+is linked; misaki_g2p_fallback_kind() then returns 0 and unknown words are
+spelled out with the lexicon's letter pronunciations. Output for those words
+then differs from what Paradee was trained on.
+
+Other flags:
+- tests/corpus/wikitext_heldout_200.txt: the first 200 sentences of
+  paradee training/data/wikitext_sents.json (WikiText-103, from Wikipedia,
+  CC-BY-SA-3.0, share-alike). Test data only.
+- num2words (LGPL-2.1) is used only by tests/compare_misaki.py to run the
+  Python reference; no num2words code is copied.

+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          excluding those notices that do not pertain to any part of

+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
