5
+ Creative Commons Corporation ("Creative Commons") is not a law firm and
6
+ does not provide legal services or legal advice. Distribution of
7
+ Creative Commons public licenses does not create a lawyer-client or
8
+ other relationship. Creative Commons makes its licenses and related
9
+ information available on an "as-is" basis. Creative Commons gives no
10

14
+
15
+ Using Creative Commons Public Licenses
16
+
17
+ Creative Commons public licenses provide a standard set of terms and
18
+ conditions that creators and other rights holders may use to share
19
+ original works of authorship and other material subject to copyright
20
+ and certain other rights specified in the public license below. The
21
+ following considerations are for informational purposes only, are not
22
+ exhaustive, and do not form part of our licenses.
23
+
24
+ Considerations for licensors: Our public licenses are
25
+ intended for use by those authorized to give the public
26
+ permission to use material in ways otherwise restricted by
27
+ copyright and certain other rights. Our licenses are
28
+ irrevocable. Licensors should read and understand the terms
29
+ and conditions of the license they choose before applying it.
30
+ Licensors should also secure all rights necessary before
31
+ applying our licenses so that the public can reuse the
32
+ material as expected. Licensors should clearly mark any
33
+ material not subject to the license. This includes other CC-
34
+ licensed material, or material used under an exception or
35
+ limitation to copyright. More considerations for licensors:
36
+ wiki.creativecommons.org/Considerations_for_licensors
37
+
38
+ Considerations for the public: By using one of our public
39
+ licenses, a licensor grants the public permission to use the
40
+ licensed material under specified terms and conditions. If
41
+ the licensor's permission is not necessary for any reason--for
42
+ example, because of any applicable exception or limitation to
43
+ copyright--then that use is not regulated by the license. Our
44
+ licenses grant only permissions under copyright and certain
45
+ other rights that a licensor has authority to grant. Use of
46
+ the licensed material may still be restricted for other
47
+ reasons, including because others have copyright or other
48
+ rights in the material. A licensor may make special requests,
49
+ such as asking that all changes be marked or described.
50
+ Although not required by our licenses, you are encouraged to
51
+ respect those requests where reasonable. More considerations
52
+ for the public:

+ categorized. For purposes of this Public License, the rights
96
+ specified in Section 2(b)(1)-(2) are not Copyright and Similar
97
+ Rights.
98
+
99
+ e. Effective Technological Measures means those measures that, in the
100
+ absence of proper authority, may not be circumvented under laws
101

+ process that requires permission under the Licensed Rights, such
127
+ as reproduction, public display, public performance, distribution,
128
+ dissemination, communication, or importation, and to make material
129
+ available to the public including in ways that members of the
130
+ public may access the material from a place and at a time
131
+ individually chosen by them.
132
+
133
+ l. Sui Generis Database Rights means rights other than copyright

+ as amended and/or succeeded, as well as other essentially
137
+ equivalent rights anywhere in the world.
138
+
139
+ m. You means the individual or entity exercising the Licensed Rights
140
+ under this Public License. Your has a corresponding meaning.
141
+
142
+
143
+ Section 2 -- Scope.
144
+
145
+ a. License grant.
146
+
147
+ 1. Subject to the terms and conditions of this Public License,
148
+ the Licensor hereby grants You a worldwide, royalty-free,
149
+ non-sublicensable, non-exclusive, irrevocable license to
150
+ exercise the Licensed Rights in the Licensed Material to:
151
+
152
+ a. reproduce and Share the Licensed Material, in whole or
153
+ in part; and
154
+
155
+ b. produce, reproduce, and Share Adapted Material.
156
+
157
+ 2. Exceptions and Limitations. For the avoidance of doubt, where
158
+ Exceptions and Limitations apply to Your use, this Public
159
+ License does not apply, and You do not need to comply with
160
+ its terms and conditions.
161
+
162
+ 3. Term. The term of this Public License is specified in Section
163
+ 6(a).
164
+
165
+ 4. Media and formats; technical modifications allowed. The
166
+ Licensor authorizes You to exercise the Licensed Rights in
167
+ all media and formats whether now known or hereafter created,
168
+ and to make technical modifications necessary to do so. The
169
+ Licensor waives and/or agrees not to assert any right or
170
+ authority to forbid You from making technical modifications
171
+ necessary to exercise the Licensed Rights, including
172
+ technical modifications necessary to circumvent Effective
173
+ Technological Measures. For purposes of this Public License,
174
+ simply making modifications authorized by this Section 2(a)
175
+ (4) never produces Adapted Material.
176
+
177
+ 5. Downstream recipients.
178
+
179
+ a. Offer from the Licensor -- Licensed Material. Every
180
+ recipient of the Licensed Material automatically
181
+ receives an offer from the Licensor to exercise the
182
+ Licensed Rights under the terms and conditions of this
183
+ Public License.
184
+
185
+ b. Additional offer from the Licensor -- Adapted Material.
186
+ Every recipient of Adapted Material from You
187
+ automatically receives an offer from the Licensor to
188
+ exercise the Licensed Rights in the Adapted Material
189
+ under the conditions of the Adapter's License You apply.
190
+
191
+ c. No downstream restrictions. You may not offer or impose
192
+ any additional or different terms or conditions on, or
193
+ apply any Effective Technological Measures to, the
194
+ Licensed Material if doing so restricts exercise of the
195
+ Licensed Rights by any recipient of the Licensed
196
+ Material.
197
+
198
+ 6. No endorsement. Nothing in this Public License constitutes or
199
+ may be construed as permission to assert or imply that You
200
+ are, or that Your use of the Licensed Material is, connected
201
+ with, or sponsored, endorsed, or granted official status by,
202
+ the Licensor or others designated to receive attribution as
203
+ provided in Section 3(a)(1)(A)(i).
204
+
205
+ b. Other rights.
206
+
207
+ 1. Moral rights, such as the right of integrity, are not
208
+ licensed under this Public License, nor are publicity,
209
+ privacy, and/or other similar personality rights; however, to
210
+ the extent possible, the Licensor waives and/or agrees not to
211
+ assert any such rights held by the Licensor to the limited
212
+ extent necessary to allow You to exercise the Licensed
213
+ Rights, but not otherwise.
214
+
215
+ 2. Patent and trademark rights are not licensed under this
216
+ Public License.
217
+
218
+ 3. To the extent possible, the Licensor waives any right to
219
+ collect royalties from You for the exercise of the Licensed
220
+ Rights, whether directly or through a collecting society
221
+ under any voluntary or waivable statutory or compulsory
222
+ licensing scheme. In all other cases the Licensor expressly
223
+ reserves any right to collect such royalties.
224
+
225
+
226
+ Section 3 -- License Conditions.
227
+
228
+ Your exercise of the Licensed Rights is expressly made subject to the
229
+ following conditions.
230
+
231
+ a. Attribution.
232
+
233
+ 1. If You Share the Licensed Material (including in modified
234
+ form), You must:
235
+
236
+ a. retain the following if it is supplied by the Licensor
237
+ with the Licensed Material:
238
+
239
+ i. identification of the creator(s) of the Licensed
240
+ Material and any others designated to receive
241
+ attribution, in any reasonable manner requested by
242
+ the Licensor (including by pseudonym if
243
+ designated);
244
+
245
+ ii. a copyright notice;
246
+
247
+ iii. a notice that refers to this Public License;
248
+
249
+ iv. a notice that refers to the disclaimer of
250
+ warranties;
251
+
252
+ v. a URI or hyperlink to the Licensed Material to the
253
+ extent reasonably practicable;
254
+
255
+ b. indicate if You modified the Licensed Material and
256
+ retain an indication of any previous modifications; and
257
+
258
+ c. indicate the Licensed Material is licensed under this
259
+ Public License, and include the text of, or the URI or
260
+ hyperlink to, this Public License.
261
+
262
+ 2. You may satisfy the conditions in Section 3(a)(1) in any
263
+ reasonable manner based on the medium, means, and context in
264
+ which You Share the Licensed Material. For example, it may be
265
+ reasonable to satisfy the conditions by providing a URI or
266
+ hyperlink to a resource that includes the required
267
+ information.
268
+
269
+ 3. If requested by the Licensor, You must remove any of the
270
+ information required by Section 3(a)(1)(A) to the extent
271
+ reasonably practicable.
272
+
273
+ b. ShareAlike.
274
+
275
+ In addition to the conditions in Section 3(a), if You Share
276
+ Adapted Material You produce, the following conditions also apply.
277
+
278
+ 1. The Adapter's License You apply must be a Creative Commons
279
+ license with the same License Elements, this version or
280
+ later, or a BY-SA Compatible License.
281
+
282
+ 2. You must include the text of, or the URI or hyperlink to, the
283
+ Adapter's License You apply. You may satisfy this condition
284
+ in any reasonable manner based on the medium, means, and
285
+ context in which You Share Adapted Material.
286
+
287
+ 3. You may not offer or impose any additional or different terms
288
+ or conditions on, or apply any Effective Technological
289
+ Measures to, Adapted Material that restrict exercise of the
290
+ rights granted under the Adapter's License You apply.
291
+
292
+
293
+ Section 4 -- Sui Generis Database Rights.
294
+
295
+ Where the Licensed Rights include Sui Generis Database Rights that
296
+ apply to Your use of the Licensed Material:
297
+
298
+ a. for the avoidance of doubt, Section 2(a)(1) grants You the right
299
+ to extract, reuse, reproduce, and Share all or a substantial
300
+ portion of the contents of the database;
301
+
302
+ b. if You include all or a substantial portion of the database
303
+ contents in a database in which You have Sui Generis Database
304
+ Rights, then the database in which You have Sui Generis Database
305
+ Rights (but not its individual contents) is Adapted Material,
306
+ including for purposes of Section 3(b); and
307
+
308
+ c. You must comply with the conditions in Section 3(a) if You Share
309
+ all or a substantial portion of the contents of the database.
310
+
311
+ For the avoidance of doubt, this Section 4 supplements and does not
312
+ replace Your obligations under this Public License where the Licensed
313
+ Rights include other Copyright and Similar Rights.
314
+
315
+
316
+ Section 5 -- Disclaimer of Warranties and Limitation of Liability.
317
+
318
+ a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
319
+ EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
320
+ AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
321
+ ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
322
+ IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
323
+ WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
324
+ PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
325
+ ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
326
+ KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
327
+ ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
328
+
329
+ b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
330
+ TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
331
+ NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
332
+ INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
333
+ COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
334
+ USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
335
+ ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
336
+ DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
337
+ IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
338
+
339
+ c. The disclaimer of warranties and limitation of liability provided
340
+ above shall be interpreted in a manner that, to the extent
341
+ possible, most closely approximates an absolute disclaimer and
342
+ waiver of all liability.
343
+
344
+
345
+ Section 6 -- Term and Termination.
346
+
347
+ a. This Public License applies for the term of the Copyright and
348
+ Similar Rights licensed here. However, if You fail to comply with
349
+ this Public License, then Your rights under this Public License
350
+ terminate automatically.
351
+
352
+ b. Where Your right to use the Licensed Material has terminated under
353
+ Section 6(a), it reinstates:
354
+
355
+ 1. automatically as of the date the violation is cured, provided
356
+ it is cured within 30 days of Your discovery of the
357
+ violation; or
358
+
359
+ 2. upon express reinstatement by the Licensor.
360
+
361
+ For the avoidance of doubt, this Section 6(b) does not affect any
362
+ right the Licensor may have to seek remedies for Your violations
363
+ of this Public License.
364
+
365
+ c. For the avoidance of doubt, the Licensor may also offer the
366
+ Licensed Material under separate terms or conditions or stop
367
+ distributing the Licensed Material at any time; however, doing so
368
+ will not terminate this Public License.
369
+
370
+ d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
371
+ License.
372
+
373
+
374
+ Section 7 -- Other Terms and Conditions.
375
+
376
+ a. The Licensor shall not be bound by any additional or different
377
+ terms or conditions communicated by You unless expressly agreed.
378
+
379
+ b. Any arrangements, understandings, or agreements regarding the
380
+ Licensed Material not stated herein are separate from and
381
+ independent of the terms and conditions of this Public License.
382
+
383
+
384
+ Section 8 -- Interpretation.
385
+
386
+ a. For the avoidance of doubt, this Public License does not, and
387
+ shall not be interpreted to, reduce, limit, restrict, or impose
388
+ conditions on any use of the Licensed Material that could lawfully
389
+ be made without permission under this Public License.
390
+
391
+ b. To the extent possible, if any provision of this Public License is
392
+ deemed unenforceable, it shall be automatically reformed to the
393
+ minimum extent necessary to make it enforceable. If the provision
394
+ cannot be reformed, it shall be severed from this Public License
395
+ without affecting the enforceability of the remaining terms and
396
+ conditions.
397
+
398
+ c. No term or condition of this Public License will be waived and no
399
+ failure to comply consented to unless expressly agreed to by the
400
+ Licensor.
401
+
402
+ d. Nothing in this Public License constitutes or may be interpreted
403
+ as a limitation upon, or waiver of, any privileges and immunities
404
+ that apply to the Licensor or You, including from the legal
405
+ processes of any jurisdiction or authority.

71

72
+ ## ONNX depthwise execution
73
+
74
+ The sherpa-onnx INT8 package includes a deterministic graph optimization of r3.
75
+ Twenty-four nine-tap depthwise integer convolutions are evaluated using centered
76
+ FP32 convolution and cast back to INT32 before the original dequantization.
77
+ The original quantized tensors, zero points, scales, tokenizer and TDT interface
78
+ are retained. No model training or new inference dependency is introduced.
79
+
80
+ Each centered input and weight lies between -255 and 255. A nine-tap partial
81
+ sum has magnitude at most 585,225, within FP32's exact integer range. Recorded
82
+ operator and complete-encoder comparisons using ONNX Runtime 1.27.0 produce
83
+ bit-identical outputs. The optimizer and its conversion evidence are available
84
+ in [Orukeet's repository](https://github.com/Oruk-AI/orukeet/tree/main/evidence/speed20260910).
85
+ The model weight license remains CC BY-SA 4.0.

+ # Orukeet v0.1.0 INT8 — sherpa-onnx layout, loose files
2
+
3
+ The same four runtime files as `onnx/sherpa-onnx-orukeet-v0.1.0-int8.tar.bz2`, stored
4
+ uncompressed so that clients which cannot extract `tar.bz2` can fetch them directly.
5
+
6
+ **Nothing here is modified.** Every file is byte-identical to the archive member of the
7
+ same name; the SHA-256 digests below are the ones published in `onnx/manifest.json`.
8
+
9
+ | File | Bytes | SHA-256 |
10
+ |:--|--:|:--|
11
+ | `encoder.int8.onnx` | 653,182,378 | `7b55f2a504a20a8e462899f5befd45f4a1784948d76ed0127902d9cf39405487` |

16
+
17
+ Total: 671,619,800 bytes, matching the archive's extracted size.
18
+
19
+ ## Why this directory exists
20
+
21
+ iOS has no `tar` and no bzip2 decompressor in this project's dependency set, so the
22
+ published `.tar.bz2` cannot be unpacked on device. Fetching the members individually
23
+ removes the need for an extraction step and for the temporary double allocation that
24
+ extraction would require.
25
+
26
+ `onnx/combined-v0.1.0-int8/` is **not** a substitute: its `decoder_joint-model.int8.onnx`
27
+ fuses the decoder and joiner into one graph for Parakeet-compatible Rust engines, and
28
+ sherpa-onnx's offline transducer loader requires them separate. Its
29
+ `encoder-model.int8.onnx`, `vocab.txt` and `bpe.vocab` are, however, the same bytes as
30
+ the corresponding files here.
31
+
32
+ ## Use
33
+
34
+ Identical to the archive — see `onnx/README.md`. Point sherpa-onnx's offline transducer
35
+ loader at the four files:
36
+
37
+ ```python
38
+ recognizer = sherpa_onnx.OfflineRecognizer.from_transducer(
39
+ encoder="encoder.int8.onnx",
40
+ decoder="decoder.int8.onnx",
41
+ joiner="joiner.int8.onnx",
42
+ tokens="tokens.txt",
43
+ model_type="nemo_transducer",
44
+ sample_rate=16000,
45
+ feature_dim=128,
46
+ decoding_method="greedy_search",
47
+ )
48
+ ```
49
+
50
+ The encoder's `url` metadata (`https://huggingface.co/oruk/orukeet#parakeet-tdt-v3`) is
51
+ preserved, as the upstream export instructions require.
52
+
