# 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
|
||||
```
|
||||
|
||||
## Using the bindings
|
||||
|
||||
To use the bindings in your own software,
|
||||
|
||||
1. Import `github.com/ggerganov/whisper.cpp/bindings/go/pkg/whisper` (or `github.com/ggerganov/whisper.cpp/bindings/go` into your package;
|
||||
2. Compile `libwhisper.a` (you can use `make whisper` in the `bindings/go` directory);
|
||||
3. Link your go binary against whisper by setting the environment variables `C_INCLUDE_PATH` and `LIBRARY_PATH`
|
||||
to point to the `whisper.h` file directory and `libwhisper.a` file directory respectively.
|
||||
|
||||
Look at the `Makefile` in the `bindings/go` directory for an example.

# whisper.cpp
|
||||
|
||||
Node.js package for Whisper speech recognition
|
||||
|
||||
Package: https://www.npmjs.com/package/whisper.cpp
|
||||
|
||||
## Details
|
||||
|
||||
The performance is comparable to when running `whisper.cpp` in the browser via WASM.
|
||||
|
||||
The API is currently very rudimentary: [bindings/javascript/emscripten.cpp](/bindings/javascript/emscripten.cpp)
|
||||
|
||||
For sample usage check [tests/test-whisper.js](/tests/test-whisper.js)
|
||||
|
||||
## Package building + test
|
||||
|
||||
```bash
|
||||
# load emscripten
|
||||
source /path/to/emsdk/emsdk_env.sh
|
||||
|
||||
# clone repo
|
||||
git clone https://github.com/ggerganov/whisper.cpp
|
||||
cd whisper.cpp
|
||||
|
||||
# grab base.en model
|
||||
./models/download-ggml-model.sh base.en
|
||||
|
||||
# prepare PCM sample for testing
|
||||
ffmpeg -i samples/jfk.wav -f f32le -acodec pcm_f32le samples/jfk.pcmf32
|
||||
|
||||
# build
|
||||
mkdir build-em && cd build-em
|
||||
emcmake cmake .. && make -j
|
||||
|
||||
# run test
|
||||
node --experimental-wasm-threads --experimental-wasm-simd ../tests/test-whisper.js
|
||||
|
||||
# publish npm package
|
||||
make publish-npm
|
||||
```
|
||||
|
||||
## Sample run
|
||||
|
||||
```java
|
||||
$ node --experimental-wasm-threads --experimental-wasm-simd ../tests/test-whisper.js

# addon
|
||||
|
||||
This is an addon demo that can **perform whisper model reasoning in `node` and `electron` environments**, based on [cmake-js](https://github.com/cmake-js/cmake-js).
|
||||
It can be used as a reference for using the whisper.cpp project in other node projects.
|
||||
|
||||
## Install
|
||||
|
||||
```shell
|
||||
npm install
|
||||
```
|
||||
|
||||
## Compile
|
||||
|
||||
Make sure it is in the project root directory and compiled with make-js.
|
||||
|
||||
```shell
|
||||
npx cmake-js compile -T whisper-addon -B Release
|
||||
```
|
||||
|
||||
For Electron addon and cmake-js options, you can see [cmake-js](https://github.com/cmake-js/cmake-js) and make very few configuration changes.
|
||||
|
||||
> Such as appointing special cmake path:
|
||||
> ```shell
|
||||
> npx cmake-js compile -c 'xxx/cmake' -T whisper-addon -B Release
|
||||
> ```
|
||||
|
||||
## Run
|
||||
|
||||
```shell
|
||||
cd examples/addon.node
|
||||
|
||||
node index.js --language='language' --model='model-path' --fname_inp='file-path'
|
||||
```
|
||||
|
||||
Because this is a simple Demo, only the above parameters are set in the node environment.
|
||||
|
||||
Other parameters can also be specified in the node environment.

# bench
|
||||
|
||||
A very basic tool for benchmarking the inference performance on your device. The tool simply runs the Encoder part of
|
||||
the transformer on some random audio data and records the execution time. This way we can have an objective comparison
|
||||
of the performance of the model for various setups.
|
||||
|
||||
Benchmark results are tracked in the following Github issue: https://github.com/ggerganov/whisper.cpp/issues/89
|
||||
|

```bash
|

# build the bench tool

# command
|
||||
|
||||
This is a basic Voice Assistant example that accepts voice commands from the microphone.
|
||||
More info is available in [issue #171](https://github.com/ggerganov/whisper.cpp/issues/171).
|
||||
|
||||
```bash
|
||||
# Run with default arguments and small model
|
||||
./command -m ./models/ggml-small.en.bin -t 8
|
||||
|
||||
# On Raspberry Pi, use tiny or base models + "-ac 768" for better performance
|
||||
./command -m ./models/ggml-tiny.en.bin -ac 768 -t 3 -c 0
|
||||
```
|
||||

||||

|
||||
|
||||
Web version: [examples/command.wasm](/examples/command.wasm)
|
||||
|
||||
## Guided mode
|
||||
|
||||
"Guided mode" allows you to specify a list of commands (i.e. strings) and the transcription will be guided to classify your command into one from the list. This can be useful in situations where a device is listening only for a small subset of commands.
|
||||
|
||||
Initial tests show that this approach might be extremely efficient in terms of performance, since it integrates very well with the "partial Encoder" idea from #137.
|
||||
|
||||
```bash
|
||||
# Run in guided mode, the list of allowed commands is in commands.txt
|
||||
./command -m ./models/ggml-base.en.bin -cmd ./examples/command/commands.txt
|
||||
|
||||
# On Raspberry Pi, in guided mode you can use "-ac 128" for extra performance
|
||||
./command -m ./models/ggml-tiny.en.bin -cmd ./examples/command/commands.txt -ac 128 -t 3 -c 0
|
||||
```
|
||||
|
||||
https://user-images.githubusercontent.com/1991296/207435352-8fc4ed3f-bde5-4555-9b8b-aeeb76bee969.mp4
|
||||
|
||||
|
||||
## Building
|
||||
|
||||
The `command` tool depends on SDL2 library to capture audio from the microphone. You can build it like this:
|
||||
|
||||
```bash
|
||||
# Install SDL2 on Linux
|
||||
sudo apt-get install libsdl2-dev
|
||||
|
||||
# Install SDL2 on Mac OS
|
||||
brew install sdl2
|
||||
|
||||
make command
|
||||
```

# stream
|
||||
|
||||
This is a naive example of performing real-time inference on audio from your microphone.
|
||||
The `stream` tool samples the audio every half a second and runs the transcription continously.
|
||||
More info is available in [issue #10](https://github.com/ggerganov/whisper.cpp/issues/10).
|
||||
|
||||
```java
|
||||
./stream -m ./models/ggml-base.en.bin -t 8 --step 500 --length 5000
|
||||
```
|
||||
|
||||
https://user-images.githubusercontent.com/1991296/194935793-76afede7-cfa8-48d8-a80f-28ba83be7d09.mp4
|
||||
|
||||
## Sliding window mode with VAD
|
||||
|
||||
Setting the `--step` argument to `0` enables the sliding window mode:
|
||||
|
||||
```java
|
||||
./stream -m ./models/ggml-small.en.bin -t 6 --step 0 --length 30000 -vth 0.6
|
||||
```
|
||||
|
||||
In this mode, the tool will transcribe only after some speech activity is detected. A very
|
||||
basic VAD detector is used, but in theory a more sophisticated approach can be added. The
|
||||
`-vth` argument determines the VAD threshold - higher values will make it detect silence more often.
|
||||
It's best to tune it to the specific use case, but a value around `0.6` should be OK in general.
|
||||
When silence is detected, it will transcribe the last `--length` milliseconds of audio and output
|
||||
a transcription block that is suitable for parsing.
|
||||
|
||||
## Building
|
||||
|
||||
The `stream` tool depends on SDL2 library to capture audio from the microphone. You can build it like this:
|
||||
|
||||
```bash
|
||||
# Install SDL2 on Linux
|
||||
sudo apt-get install libsdl2-dev
|
||||
|
||||
# Install SDL2 on Mac OS
|
||||
brew install sdl2
|
||||
|
||||
make stream
|
||||
```
|
||||
|
||||
## Web version
|
||||
|
||||
This tool can also run in the browser: [examples/stream.wasm](/examples/stream.wasm)

Talk with an Artificial Intelligence in your browser:
|
||||
|
||||
[https://user-images.githubusercontent.com/1991296/203411580-fedb4839-05e4-4474-8364-aaf1e9a9b615.mp4](https://user-images.githubusercontent.com/1991296/203845553-f7b44e13-9a15-4fc8-b518-ae8f4c6770fe.mp4)
|
||||
|
||||
Online demo: https://whisper.ggerganov.com/talk/
|
||||
|
||||
Terminal version: [examples/talk](/examples/talk)
|
||||
|
||||
## How it works?
|
||||
|
||||
This demo leverages 2 modern neural network models to create a high-quality voice chat directly in your browser:
|
||||
|
||||
- [OpenAI's Whisper](https://github.com/openai/whisper) speech recognition model is used to process your voice and understand what you are saying
|
||||
- Upon receiving some voice input, the AI generates a text response using [OpenAI's GPT-2](https://github.com/openai/gpt-2) language model
|
||||
- The AI then vocalizes the response using the browser's [Web Speech API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Speech_API)
|
||||
|
||||
The web page does the processing locally on your machine. The processing of these heavy neural network models in the
|
||||
browser is possible by implementing them efficiently in C/C++ and using the browser's WebAssembly SIMD capabilities for
|
||||
extra performance:
|
||||
|
||||
- The Whisper C++ implementation is here: [whisper.h](/whisper.h) / [whisper.cpp](/whisper.cpp)
|
||||
- The GPT-2 C++ implementation is here: [gpt-2.h](gpt-2.h) / [gpt-2.cpp](gpt-2.cpp)
|
||||
- Both models use a custom tensor library implemented in C: [ggml.h](/ggml.h) / [ggml.c](/ggml.c)
|
||||
- The HTML/JS layer is here: [index-tmpl.html](index-tmpl.html)
|
||||
- The Emscripten bridge between C/C++ and JS is here: [emscripten.cpp](emscripten.cpp)
|
||||
|
||||
In order to run the models, the web page first needs to download the model data which is about ~350 MB. The model data
|
||||
is then cached in your browser's cache and can be reused in future visits without downloading it again.
|
||||
|
||||
## Requirements
|
||||
|
||||
In order to run this demo efficiently, you need to have the following:
|
||||
|
||||
- Latest Chrome or Firefox browser (Safari is not supported)
|
||||
- Run this on a desktop or laptop with modern CPU (a mobile phone will likely not be good enough)
|
||||
- Speak phrases that are no longer than 10 seconds - this is the audio context of the AI
|
||||
- The web-page uses about 1.8GB of RAM
|
||||
|
||||
Notice that this demo is using the smallest GPT-2 model, so the generated text responses are not always very good.
|
||||
Also, the prompting strategy can likely be improved to achieve better results.
|
||||
|
||||
The demo is quite computationally heavy, so you need a fast CPU. It's not usual to run these transformer models in a
|
||||
browser. Typically, they run on powerful GPUs.
|
||||
|
||||
Currently, mobile browsers do not support the Fixed-width SIMD WebAssembly capability, so you cannot run this demo
|
||||
on a phone or a tablet. Hopefully, in the near future this will become supported.
|
||||
|
||||
## Todo
|
||||
|
||||
- Better UI (contributions are welcome)
|
||||
- Better GPT-2 prompting
|
||||
|
||||

<b>Talk - GPT-2 meets Whisper in WebAssembly</b>
|

<br><br>
|
||||
|
||||
Talk with an Artificial Intelligence in your browser. This demo uses:
|
||||
|
||||
<ul>
|
||||
<li><a href="https://github.com/ggerganov/whisper.cpp">OpenAI's Whisper</a> to listen to you as you speak in the microphone</li>
|
||||
<li><a href="https://github.com/ggerganov/whisper.cpp/tree/master/examples/talk.wasm">OpenAI's GPT-2</a> to generate text responses</li>
|
||||
<li><a href="https://developer.mozilla.org/en-US/docs/Web/API/Web_Speech_API">Web Speech API</a> to vocalize the responses through your speakers</li>
|
||||
</ul>
|
||||
|
||||
All of this runs <b>locally in your browser</b> using WebAssembly.<br>
|
||||

<b>Troubleshooting</b>
|
||||
|
||||
<br><br>
|
||||
|
||||
The page does some heavy computations, so make sure:
|
||||
|
||||
<ul>
|
||||
<li>To use a modern web browser (e.g. Chrome, Firefox)</li>
|
||||
<li>To use a fast desktop or laptop computer (i.e. not a mobile phone)</li>
|
||||
<li>Your browser supports WASM <a href="https://webassembly.org/roadmap/">Fixed-width SIMD</a></li>
|
||||
</ul>
|
||||
|
||||
Note that these neural network models were not meant to be used in a browser, so the performance and <br>
|
||||
quality of the results may not be optimal. If you have any questions or suggestions, checkout the following
