# whisper.wasm
|
|
|
|
Inference of [OpenAI's Whisper ASR model](https://github.com/openai/whisper) inside the browser
|
|
|
|
This example uses a WebAssembly (WASM) port of the [whisper.cpp](https://github.com/ggerganov/whisper.cpp)
|
|
implementation of the transformer to run the inference inside a web page. The audio data does not leave your computer -
|
|
it is processed locally on your machine. The performance is not great but you should be able to achieve x2 or x3
|
|
real-time for the `tiny` and `base` models on a modern CPU and browser (i.e. transcribe a 60 seconds audio in about
|
|
~20-30 seconds).
|
|
|
|
This WASM port utilizes [WASM SIMD 128-bit intrinsics](https://emcc.zcopy.site/docs/porting/simd/) so you have to make
|
|
sure that [your browser supports them](https://webassembly.org/roadmap/).
|
|
|
|
The example is capable of running all models up to size `small` inclusive. Beyond that, the memory requirements and
|
|
performance are unsatisfactory. The implementation currently support only the `Greedy` sampling strategy. Both
|
|
transcription and translation are supported.
|
|
|
|
Since the model data is quite big (74MB for the `tiny` model) you need to manually load the model into the web-page.
|
|
|
|
The example supports both loading audio from a file and recording audio from the microphone. The maximum length of the
|
|
audio is limited to 120 seconds.

## Live demo
|
|
|
|
Link: https://ggerganov.github.io/whisper.cpp/
|
|
|
|
|
|
|
|
## Build instructions
|
|
|
|
```bash (v3.1.2)
|
|
# build using Emscripten
|
|
git clone https://github.com/ggerganov/whisper.cpp
|
|
cd whisper.cpp
|
|
mkdir build-em && cd build-em
|
|
emcmake cmake ..
|
|
make -j
|
|
```
|
|
The example can then be started by running a local HTTP server:
|
|
```console
|
|
python3 examples/server.py
|
|
```
|
|
And then opening a browser to the following URL:
|
|
http://localhost:8000/whisper.wasm
|
|
|
|
To run the example in a different server, you need to copy the following files
|
|
to the server's HTTP path:
|
|
```
|
|
# copy the produced page to your HTTP path
|
|
cp bin/whisper.wasm/* /path/to/html/
|
|
cp bin/libmain.worker.js /path/to/html/
|
|
```
