This is a nuget-based wrapper for libvosk library
See demo folder for example how to use the library. You can simply run
"dotnet run" to run the demo. Make sure you unpacked the model and the
test file.
See the nuget folder for the sources of the wrapper. Run build.sh to
build nuget package.
Note we only support win64 and linux64 for now. No support for win32
since it is a little bit painful to load the libraries depending on
architecture. In theory we can add OSX some time or even Android.

<title>Vosk Speech Recognition Toolkit</title>
<description>Vosk is an offline open source speech recognition toolkit. It enables speech recognition models for 20+ languages and dialects - English, Indian English, German, French, Spanish, Portuguese, Chinese, Russian, Turkish, Vietnamese, Italian, Dutch, Catalan, Arabic, Greek, Farsi, Filipino, Ukrainian, Kazakh, Swedish, Japanese, Esperanto, Hindi, Czech. More to come.
Vosk models are small (50 Mb) but provide continuous large vocabulary transcription, zero-latency response with streaming API, reconfigurable vocabulary and speaker identification.
Speech recognition bindings implemented for various programming languages like Python, Java, Node.JS, C#, C++ and others.
Vosk supplies speech recognition for chatbots, smart home appliances, virtual assistants. It can also create subtitles for movies, transcription for lectures and interviews.
Vosk scales from small devices like Raspberry Pi or Android smartphone to big clusters.</description>

manner that imitates the Python example of [test_gpu_batch.py](../python/example/test_gpu_batch.py).
Note that the `libvosk.so` must be in the library path. This was successfully tested on

# Maintenance
To maintain this module, please ensure the following.
1. Kotlin version is kept up to date.
This will be found in the plugins block of the [build.gradle.kts](./build.gradle.kts).
Ensure both multiplatform and serialization have the same value.
2. Ensure dependencies are up to date
3. Ensure that the android min & target sdks are up to date.

# vosk-api-kotlin
The vosk-api wrapped using Kotlin Multiplatform.
## Usage
The following are ways to use this wrapper.
### JVM
For Java & Android targets.
```kotlin
dependencoes {
val voskVersion = "0.4.0-alpha0"
// Generic
implementation("com.alphacephei:vosk-api-kotlin:$voskVersion")
// Android
implementation("com.alphacephei:vosk-api-kotlin-android:$voskVersion")
}
```
## Building
To build this project, follow the following steps.
1. Install `libvosk`.
This can be done from [source][source install] (parent monorepo)
or [downloaded][download].
2. Download a [Vosk model](https://alphacephei.com/vosk/models) to use.
- It is suggested to use a small model to speed up tests.
3. Once both are downloaded and placed into a proper location (hopefully following UNIX specification).
Set the following environment variables:
- `VOSK_MODEL` to the path of the model.
- `VOSK_PATH` to the path of `libvosk`.
These are used by the various tests to operate.
4. Now that the required steps are complete, one can run `./gradlew build`.
## Kotlin/Native
Currently, the native target is disabled due to a lack of vosk-api packaging on platforms.
Further worsened by the fact that installing the vosk-api on Linux systems is a chore.
First, either install from [source][source install]
or [download][download] and install into the proper unix directories as expected in
[libvosk.def](./src/nativeInterop/cinterop/libvosk.def).
To enable development for Kotlin/Native, do either for the following.
- Add `NATIVE_EXPERIMENT=true` to your environment.
- Go into [build.gradle.kts](./build.gradle.kts) & find `enableNative` & set the right side to true.
Afterwards, when syncing the project, the native source sets will become available to work on.
It is suggested to run `cinteropLibvoskNative` to generate the Kotlin C bindings to work with.
## Future
- Possibly target Kotlin/JS
- Possibly target Kotlin/Objective-C (?)
