# whisper.cpp

> Port of OpenAI's Whisper model in C/C++ for speech-to-text inference

A repository containing a port of the Whisper ASR model, optimized with the `ggml` library to transcribe audio files into text. Primarily useful for developers who need a lightweight and performant solution for integrating speech recognition capabilities.

## Quick start

First clone the repository:

```bash
git clone https://github.com/ggml-org/whisper.cpp.git
```

Navigate into the directory:

```
cd whisper.cpp
```

Then, download one of the Whisper [models](models/README.md) converted in [`ggml` format](#ggml-format). For example:

```bash
sh ./models/download-ggml-model.sh base.en
```

Now build the [whisper-cli](examples/cli) example and transcribe an audio file like this:

```bash
````
