TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||||
|
|
||||||
|
1. Definitions.
|
||||||
|
|
||||||
|
"License" shall mean the terms and conditions for use, reproduction,
|
||||||
|
and distribution as defined by Sections 1 through 9 of this document.
|
||||||
|
|
||||||
|
"Licensor" shall mean the copyright owner or entity authorized by
|
||||||
|
the copyright owner that is granting the License.
|
||||||
|
|
||||||
|
"Legal Entity" shall mean the union of the acting entity and all
|
||||||
|
other entities that control, are controlled by, or are under common
|
||||||
|
control with that entity. For the purposes of this definition,
|
||||||
|
"control" means (i) the power, direct or indirect, to cause the
|
||||||
|
direction or management of such entity, whether by contract or
|
||||||
|
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||||
|
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||||
|
|
||||||
|
"You" (or "Your") shall mean an individual or Legal Entity
|
||||||
|
exercising permissions granted by this License.
|
||||||
|
|
||||||
|
"Source" form shall mean the preferred form for making modifications,
|
||||||
|
including but not limited to software source code, documentation
|
||||||
|
source, and configuration files.
|
||||||
|
|
||||||
|
"Object" form shall mean any form resulting from mechanical
|
||||||
|
transformation or translation of a Source form, including but
|
||||||
|
not limited to compiled object code, generated documentation,
|
||||||
|
and conversions to other media types.
|
||||||
|
|
||||||
|
"Work" shall mean the work of authorship, whether in Source or
|
||||||
|
Object form, made available under the License, as indicated by a
|
||||||
|
copyright notice that is included in or attached to the work
|
||||||
|
(an example is provided in the Appendix below).
|
||||||
|
|
||||||
|
"Derivative Works" shall mean any work, whether in Source or Object
|
||||||
|
form, that is based on (or derived from) the Work and for which the
|
||||||
|
editorial revisions, annotations, elaborations, or other modifications
|
||||||
|
represent, as a whole, an original work of authorship. For the purposes
|
||||||
|
of this License, Derivative Works shall not include works that remain
|
||||||
|
separable from, or merely link (or bind by name) to the interfaces of,
|
||||||
|
the Work and Derivative Works thereof.
|
||||||
|
|
||||||
|
"Contribution" shall mean any work of authorship, including
|
||||||
|
the original version of the Work and any modifications or additions
|
||||||
|
to that Work or Derivative Works thereof, that is intentionally
|
||||||
|
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||||
|
or by an individual or Legal Entity authorized to submit on behalf of
|
||||||
|
the copyright owner. For the purposes of this definition, "submitted"
|
||||||
|
means any form of electronic, verbal, or written communication sent
|
||||||
|
to the Licensor or its representatives, including but not limited to
|
||||||
|
communication on electronic mailing lists, source code control systems,
|
||||||
|
and issue tracking systems that are managed by, or on behalf of, the
|
||||||
|
Licensor for the purpose of discussing and improving the Work, but
|
||||||
|
excluding communication that is conspicuously marked or otherwise
|
||||||
|
designated in writing by the copyright owner as "Not a Contribution."
|
||||||
|
|
||||||
|
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||||
|
on behalf of whom a Contribution has been received by Licensor and
|
||||||
|
subsequently incorporated within the Work.
|
||||||
|
|
||||||
|
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
copyright license to reproduce, prepare Derivative Works of,
|
||||||
|
publicly display, publicly perform, sublicense, and distribute the
|
||||||
|
Work and such Derivative Works in Source or Object form.
|
||||||
|
|
||||||
|
3. Grant of Patent License. Subject to the terms and conditions of
|
||||||
|
this License, each Contributor hereby grants to You a perpetual,
|
||||||
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||||
|
(except as stated in this section) patent license to make, have made,
|
||||||
|
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||||
|
where such license applies only to those patent claims licensable
|
||||||
|
by such Contributor that are necessarily infringed by their
|
||||||
|
Contribution(s) alone or by combination of their Contribution(s)
|
||||||
|
with the Work to which such Contribution(s) was submitted. If You
|
||||||
|
institute patent litigation against any entity (including a
|
||||||
|
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||||
|
or a Contribution incorporated within the Work constitutes direct
|
||||||
|
or contributory patent infringement, then any patent licenses
|
||||||
|
granted to You under this License for that Work shall terminate
|
||||||
|
as of the date such litigation is filed.
|
||||||
|
|
||||||
|
4. Redistribution. You may reproduce and distribute copies of the
|
||||||
|
Work or Derivative Works thereof in any medium, with or without
|
||||||
|
modifications, and in Source or Object form, provided that You
|
||||||
|
meet the following conditions:
|
||||||
|
|
||||||
|
(a) You must give any other recipients of the Work or
|
||||||
|
Derivative Works a copy of this License; and
|
||||||
|
|
||||||
|
(b) You must cause any modified files to carry prominent notices
|
||||||
|
stating that You changed the files; and
|
||||||
|
|
||||||
|
(c) You must retain, in the Source form of any Derivative Works
|
||||||
|
that You distribute, all copyright, patent, trademark, and
|
||||||
|
attribution notices from the Source form of the Work,
|
||||||
|
excluding those notices that do not pertain to any part of
|
||||||
|
the Derivative Works; and
|
||||||
|
|
||||||
|
(d) If the Work includes a "NOTICE" text file as part of its
|
||||||
|
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
|
||||||
|
documentation, if provided along with the Derivative Works; 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
|
||||||
|
implied, including, without limitation, any warranties or conditions
|
||||||
|
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||||
|
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
|

# Common Questions for a Commercial Application
|
||||||
|
|
||||||
|
You are looking for a way to put Snowboy in a commercial application. We have compiled a large collection of common questions from our customers all over the world in various industries.
|
||||||
|
|
||||||
|
|
||||||
|
## Universal models (paid) vs. personal models (free)
|
||||||
|
|
||||||
|
Personal models:
|
||||||
|
|
||||||
|
* are the models you downloaded from https://snowboy.kitt.ai or using our `/train` SaaS API.
|
||||||
|
* are good for quick demos
|
||||||
|
* are built with only 3 voice samples
|
||||||
|
* are not noise robust and you'll get a lot of false alarms in real environment
|
||||||
|
* only work on your own voice or a very similar voice, thus is speaker dependent
|
||||||
|
* are free
|
||||||
|
|
||||||
|
Universal models:
|
||||||
|
|
||||||
|
* are built using a lot more voice samples (at least thousands)
|
||||||
|
* take effort to collect those voice samples
|
||||||
|
* take a lot of GPU time to train
|
||||||
|
* are more robust against noise
|
||||||
|
* are mostly speaker independent (with challenges on children's voice and accents)
|
||||||
|
* cannot be built by yourself using the web interface or the SaaS API
|
||||||
|
* cost you money
|
||||||
|
|
||||||
|
### FAQ for universal & personal models
|
||||||
|
|
||||||
|
Q: **If I record multiple times on snowboy.kitt.ai, can I improve the personal models?**
|
||||||
|
A: No. Personal models only take 3 voice samples to build. Each time you record new voices, the previous samples are overwritten and not used in your current model.
|
||||||
|
|
||||||
|
|
||||||
|
Q: **How can I get a universal model for free?**
|
||||||
|
A: The *one and only* way: Ask 500 people to log in to snowboy.kitt.ai, contribute their voice samples to a particular hotword, then ask us to build a universal model for that hotword.
|
||||||
|
|
||||||
|
Q: **Can I use your API to collect voices from 500 people and increment the sample counter from snowboy.kitt.ai?**
|
||||||
|
A: No. The [SaaS](https://github.com/kitt-ai/snowboy#hotword-as-a-service) API is separate from the website.
|
||||||
|
|
||||||
|
Q: **How long does it take to get a universal model?**
|
||||||
|
A: Usually a month.
|
||||||
|
|
||||||
|
## Licensing
|
||||||
|
|
||||||
|
|
||||||
|
### Explain your license again?
|
||||||
|
|
||||||
|
Everything on Snowboy's GitHub repo is Apache licensed, including various sample applications and wrapper codes, though the Snowboy library is binary code compiled against different platforms.
|
||||||
|
|
||||||
|
With that said, if you built an application from https://github.com/kitt-ai/snowboy or personal models downloaded from https://snowboy.kitt.ai, you don't need to pay a penny.
|
||||||
|
|
||||||
|
If you want to use a universal model with your own customized hotword, you'll need an **evaluation license** and a **commercial license**.
|
||||||
|
|
||||||
|
### Evaluation license
|
||||||
|
|
||||||
|
Each hotword is different. When you train a universal model with your own hotword, nobody can guarantee that it works on your system without any flaws. Thus you'll need to get an evaluation license first to test whether your universal model works for you.
|
||||||
|
|
||||||
|
An evaluation license:
|
||||||
|
|
||||||
|
* gives you a 90 day window to evaluate the universal model we build for you
|
||||||
|
* costs you money
|
||||||
|
|
||||||
|
**Warning: an evaluation license will expire after 90 days. Make sure you don't use the model with evaluation license in production systems.** Get a commercial license from us for your production system.
|
||||||
|
|
||||||
|
#### Evaluation license FAQ
|
||||||
|
|
||||||
|
Q: **How much does it cost?**
|
||||||
|
A: A few thousand dollars.
|
||||||
|
|
||||||
|
Q: **Can I get a discount as a {startup, student, NGO}?**
|
||||||
|
A: No. Our pricing is already at least half of what others charge.
|
||||||
|
|
||||||
|
Q: **How can you make sure your universal model works for me?**
|
||||||
|
A: We simply can't. However we have a few sample universal models from our GitHub [repo](https://github.com/Kitt-AI/snowboy/tree/master/resources), including "alexa.umdl", "snowboy.umdl", and "smart_mirror.umdl". The "alexa.umdl" model is enhanced with a lot more data and is not a typical case. So pay attention to test "snowboy.umdl" and "smart_mirror.umdl". They offer similar performance to your model.
|
||||||
|
|
||||||
|
|
||||||
|
### Commercial license
|
||||||
|
|
||||||
|
After evaluation, if you feel want to go with Snowboy, you'll need a commercial license to deploy it. We usually charge a flat fee per unit of hardware you sell.
|
||||||
|
|
||||||
|
#### Commercial license FAQ
|
||||||
|
|
||||||
|
Q: **Is it a one-time license or subscription-based license?**
|
||||||
|
A: It's a perpetual license for each device. Since the Snowboy library runs *offline* on your device, you can run it forever without worrying about any broken and dependent web services.
|
||||||
|
|
||||||
|
Q: **What's your pricing structure?**
|
||||||
|
A: We have tiered pricing depending on your volume. We charge less if you sell more.
|
||||||
|
|
||||||
|
Q: **Can you give me one example?**
|
||||||
|
A: For instance, if your product is a talking robot with a $300 price tag, and you sell at least 100,000 units per year, we'll probably charge you $1 per unit once you go over 100,000 units. If your product is a smart speaker with a $30 price tag, we won't charge you $1, but you'll have to sell a lot more to make the business sense to us.
|
||||||
|
|
||||||
|
Q: **I plan to sell 1000 units a year, can I license your software for $1 per unit?**
|
||||||
|
A: No. In that way we only make $1000 a year, which is not worth the amount of time we put on your hotword.
|
||||||
|
|
||||||
|
Q: **I make a cellphone app, not a hardware product, what's the pricing structure?**
|
||||||
|
A: Depends on how you generate revenue. For instance, if your app is priced at $1.99, we'll collect cents per paid user, assuming you have a large user base. If you only have 2000 paid users, we'll make a revenue of less than a hundred dollars and it won't make sense to us.
|
||||||
|
|
||||||
|
|
||||||
|
### What's the process of getting a license?
|
||||||
|
|
||||||
|
1. Make sure Snowboy can run on your system
|
||||||
|
2. Reach out to us with your hotword name, commercial application, and target market
|
||||||
|
3. Discuss with us about **commercial license** fee to make sure our pricing fits your budget
|
||||||
|
4. Sign an evaluation contract, pay 50% of invoice
|
||||||
|
5. We'll train a universal model for you and give you an **evaluation license** of 90 days
|
||||||
|
6. Test the model and discuss how we can improve it
|
||||||
|
7. If you decide to go with it, get a commercial license from us
|
||||||
|
|
||||||
|
## General Questions
|
||||||
|
|
||||||
|
### What language does Snowboy support?
|
||||||
|
|
||||||
|
We support North American English and Chinese the best. We can deal with a bit of Indian accents as well. For other languages, we'll need to first listen to your hotword (please send us a few .wav voice samples) before we can engage.
|
||||||
|
|
||||||
|
### How many voice samples do you need?
|
||||||
|
|
||||||
|
Usually 1500 voice samples from 500 people to get started. The more the better. If your hotword is in English, we can collect the voice samples for you. Otherwise you'll need to collect it yourself and send to us.
|
||||||
|
|
||||||
|
### What's the format on voice samples?
|
||||||
|
|
||||||
|
16000Hz sample rate, 16 bit integer, mono channel, .wav files.
|
||||||
|
|
||||||
|
### Does Snowboy do: AEC, VAD, Noise Suppression, Beam Forming?
|
||||||
|
|
||||||
|
Snowboy has a weak support for VAD and noise suppression, as we found some customers would use Snowboy without a microphone array. Snowboy is not a audio frontend processing toolkit thus does not support AEC and beam forming.
|
||||||
|
|
||||||
|
If your application wants to support far-field speech, i.e., verbal communication at least 3 feet away, you'll need a microphone array to enhance incoming speech and reduce noise. Please do not reply on Snowboy to do everything.
|
||||||
|
|
||||||
|
### Can you compile Snowboy for my platform?
|
||||||
|
|
||||||
|
If your platform is not listed [here](https://github.com/Kitt-AI/snowboy/tree/master/lib), and you want to get a commercial license from us, please contact us with your toolchain, hardware chip, RAM, OS, GCC/G++ version. Depending on the effort, we might charge an NRE fee for cross compiling.

# Snowboy Demo on Android
|
||||||
|
|
||||||
|
Note:
|
||||||
|
|
||||||
|
1. supported building platforms are Android Studio running on Mac OS X or Ubuntu. Windows is not supported.
|
||||||
|
2. supported target CPU is ARMv7 (32bit) and ARMv8 (64bit) (most Android phones run on ARM CPUs)
|
||||||
|
3. we have prepared an Android app which can be installed and run out of box: [SnowboyAlexaDemo.apk](https://github.com/Kitt-AI/snowboy/raw/master/resources/alexa/SnowboyAlexaDemo.apk) (please uninstall any previous one first if you installed this app before).
|
||||||
|
|
||||||
|
## General Workflow
|
||||||
|
|
||||||
|
1. Install `swig`. For Mac, do `brew install swig`; for Ubuntu, do `sudo apt-get install swig3.0`. Make sure your `swig` version is at least `3.0.10`. You'll also need `wget` to download files.
|
||||||
|
|
||||||
|
2. Go to `swig/Android` and build swig wrappers for Snowboy:
|
||||||
|
|
||||||
|
cd swig/Android
|
||||||
|
make
|
||||||
|
|
||||||
|
To make for ARMv8 64bit:
|
||||||
|
|
||||||
|
make BIT=64
|
||||||
|
|
||||||
|
Ths will generate a cross-compiled library for ARM:
|
||||||
|
|
||||||
|
jniLibs/
|
||||||
|
├── arm64-v8a
|
||||||
|
│ └── libsnowboy-detect-android.so
|
||||||
|
└── armeabi-v7a
|
||||||
|
└── libsnowboy-detect-android.so
|
||||||
|
|
||||||
|
and a few Java wrapper files:
|
||||||
|
|
||||||
|
java
|
||||||
|
└── ai
|
||||||
|
└── kitt
|
||||||
|
└── snowboy
|
||||||
|
├── SnowboyDetect.java
|
||||||
|
├── snowboy.java
|
||||||
|
└── snowboyJNI.java
|
||||||
|
|
||||||
|
The generated `.so` and `.java` files are hyperlinked to the `examples/Android/SnowboyAlexaDemo` folder.
|
||||||
|
|
||||||
|
3. Use Android Studio to open the project in `examples/Android/SnowboyAlexaDemo` and run it.
|
||||||
|
|
||||||
|
Screenshot (say "Alexa" after clicking "Start"):
|
||||||
|
|
||||||
|
<img src="https://s3-us-west-2.amazonaws.com/kittai-cdn/Snowboy/SnowboyAlexaDemo-Andriod.jpeg" alt="Android Alexa Demo" width=300 />
|
||||||
|
|
||||||
|
|
||||||
|
Don't forget to disable the "debug" option when releasing your Android App!
|
||||||
|
|
||||||
|
Note: If you need to copy the Android demo to another folder, please use the `-RL` option of `cp` to replace the relative symbol links with real files:
|
||||||
|
|
||||||
|
cp -RL SnowboyAlexaDemo Other_Folder
|
||||||
|
|
||||||
|
Note: The sample app will save/overwrite all audio to a file (`recording.pcm`). Make sure you do not leave it on for a long time.
|
||||||
|
|
||||||
|
## Useful Code Snippets
|
||||||
|
|
||||||
|
|
||||||
|
To initialize Snowboy detector in Java:
|
||||||
|
|
||||||
|
# Assume you put the model related files under /sdcard/snowboy/
|
||||||
|
SnowboyDetect snowboyDetector = new SnowboyDetect("/sdcard/snowboy/common.res",
|
||||||
|
"/sdcard/snowboy/snowboy.umdl");
|
||||||
|
snowboyDetector.SetSensitivity("0.45"); // Sensitivity for each hotword
|
||||||
|
snowboyDetector.SetAudioGain(2.0); // Audio gain for detection
|
||||||
|
|
||||||
|
To run hotword detection in Java:
|
||||||
|
|
||||||
|
int result = snowboyDetector.RunDetection(buffer, buffer.length); // buffer is a short array.
|
||||||
|
|
||||||
|
You may want to play with the frequency of the calls to `RunDetection()`, which controls the CPU usage and the detection latency.
|
||||||
|
|
||||||
|
|
||||||
|
## Common Asks
|
||||||
|
|
||||||
|
The following issues have been fixed pushed to `master`.
|
||||||
|
|
||||||
|
- [x] softfloating point support with OpenBlas
|
||||||
|
- [x] upgrade NDK version to newer than r11c
|
||||||
|
- [x] NDK toolchain building: remove `--stl=libc++` option
