# Go bindings for Whisper
This package provides Go bindings for whisper.cpp. They have been tested on:
* Darwin (OS X) 12.6 on x64_64
* Debian Linux on arm64
* Fedora Linux on x86_64
The "low level" bindings are in the `bindings/go` directory and there is a more
Go-style package in the `bindings/go/pkg/whisper` directory. The most simple usage
is as follows:
```go
import (
"github.com/ggerganov/whisper.cpp/bindings/go/pkg/whisper"
)
func main() {
var modelpath string // Path to the model
var samples []float32 // Samples to process
// Load the model
model, err := whisper.New(modelpath)
if err != nil {
panic(err)
}
defer model.Close()
// Process samples
context, err := model.NewContext()
if err != nil {
panic(err)
}
if err := context.Process(samples, nil); err != nil {
return err
}
// Print out the results
for {
segment, err := context.NextSegment()
if err != nil {
break
}
fmt.Printf("[%6s->%6s] %s\n", segment.Start, segment.End, segment.Text)
}
}
```
## Building & Testing
In order to build, you need to have the Go compiler installed. You can get it from [here](https://golang.org/dl/). Run the tests with:
```bash
git clone https://github.com/ggerganov/whisper.cpp.git
cd whisper.cpp/bindings/go
make test
```
This will compile a static `libwhisper.a` in a `build` folder, download a model file, then run the tests. To build the examples:
```bash
make examples
```
The examples are placed in the `build` directory. Once built, you can download all the models with the following command:
```bash
./build/go-model-download -out models
```
And you can then test a model against samples with the following command:
```bash
./build/go-whisper -model models/ggml-tiny.en.bin samples/jfk.wav
```
