## Notebook
If you wish to try this on Colab, you can do it in [here](https://colab.research.google.com/github/jhj0517/Whisper-WebUI/blob/master/notebook/whisper-webui.ipynb)!

# Feature
- Select the Whisper implementation you want to use between :
   - [openai/whisper](https://github.com/openai/whisper)
   - [SYSTRAN/faster-whisper](https://github.com/SYSTRAN/faster-whisper) (used by default)
   - [Vaibhavs10/insanely-fast-whisper](https://github.com/Vaibhavs10/insanely-fast-whisper)
- Generate subtitles from various sources, including :
  - Files
  - Youtube
  - Microphone
- Currently supported subtitle formats : 
  - SRT
  - WebVTT
  - txt ( only text file without timeline )
- Speech to Text Translation 
  - From other languages to English. ( This is Whisper's end-to-end speech-to-text translation feature )
- Text to Text Translation
  - Translate subtitle files using Facebook NLLB models
  - Translate subtitle files using DeepL API
- Pre-processing audio input with [Silero VAD](https://github.com/snakers4/silero-vad).
- Pre-processing audio input to separate BGM with [UVR](https://github.com/Anjok07/ultimatevocalremovergui). 
- Post-processing with speaker diarization using the [pyannote](https://huggingface.co/pyannote/speaker-diarization-3.1) model.
   - To download the pyannote model, you need to have a Huggingface token and manually accept their terms in the pages below.

# Installation and Running

- ## Running with Pinokio

The app is able to run with [Pinokio](https://github.com/pinokiocomputer/pinokio).

1. Install [Pinokio Software](https://program.pinokio.computer/#/?id=install).
2. Open the software and search for Whisper-WebUI and install it.
3. Start the Whisper-WebUI and connect to the `http://localhost:7860`.

- ## Running with Docker 

1. Install and launch [Docker-Desktop](https://www.docker.com/products/docker-desktop/).

2. Git clone the repository

```sh
git clone https://github.com/jhj0517/Whisper-WebUI.git
```

3. Build the image ( Image is about 7GB~ )

```sh
docker compose build 
```

4. Run the container 

```sh
docker compose up
```

5. Connect to the WebUI with your browser at `http://localhost:7860`

If needed, update the [`docker-compose.yaml`](https://github.com/jhj0517/Whisper-WebUI/blob/master/docker-compose.yaml) to match your environment.

- ## Run Locally

### Prerequisite
To run this WebUI, you need to have `git`, `3.10 <= python <= 3.12`, `FFmpeg`. <br>
And if you're not using an Nvida GPU, or using a different `CUDA` version than 12.4,  edit the [`requirements.txt`](https://github.com/jhj0517/Whisper-WebUI/blob/master/requirements.txt) to match your environment.

Please follow the links below to install the necessary software:
- git : [https://git-scm.com/downloads](https://git-scm.com/downloads)
- python : [https://www.python.org/downloads/](https://www.python.org/downloads/) **`3.10 ~ 3.12` is recommended.** 
- FFmpeg :  [https://ffmpeg.org/download.html](https://ffmpeg.org/download.html)
- CUDA : [https://developer.nvidia.com/cuda-downloads](https://developer.nvidia.com/cuda-downloads)

After installing FFmpeg, **make sure to add the `FFmpeg/bin` folder to your system PATH!**

### Automatic Installation

1. git clone this repository
```shell
git clone https://github.com/jhj0517/Whisper-WebUI.git
```
2. Run `install.bat` or `install.sh` to install dependencies. (It will create a `venv` directory and install dependencies there.)
3. Start WebUI with `start-webui.bat` or `start-webui.sh` (It will run `python app.py` after activating the venv)

And you can also run the project with command line arguments if you like to, see [wiki](https://github.com/jhj0517/Whisper-WebUI/wiki/Command-Line-Arguments) for a guide to arguments.

# VRAM Usages
This project is integrated with [faster-whisper](https://github.com/guillaumekln/faster-whisper) by default for better VRAM usage and transcription speed.

According to faster-whisper, the efficiency of the optimized whisper model is as follows: 
| Implementation    | Precision | Beam size | Time  | Max. GPU memory | Max. CPU memory |
|-------------------|-----------|-----------|-------|-----------------|-----------------|
| openai/whisper    | fp16      | 5         | 4m30s | 11325MB         | 9439MB          |
| faster-whisper    | fp16      | 5         | 54s   | 4755MB          | 3244MB          |

If you want to use an implementation other than faster-whisper, use `--whisper_type` arg and the repository name.<br>
Read [wiki](https://github.com/jhj0517/Whisper-WebUI/wiki/Command-Line-Arguments) for more info about CLI args.

## Available models
This is Whisper's original VRAM usage table for models.

|  Size  | Parameters | English-only model | Multilingual model | Required VRAM | Relative speed |
|:------:|:----------:|:------------------:|:------------------:|:-------------:|:--------------:|
|  tiny  |    39 M    |     `tiny.en`      |       `tiny`       |     ~1 GB     |      ~32x      |
|  base  |    74 M    |     `base.en`      |       `base`       |     ~1 GB     |      ~16x      |
| small  |   244 M    |     `small.en`     |      `small`       |     ~2 GB     |      ~6x       |
| medium |   769 M    |    `medium.en`     |      `medium`      |     ~5 GB     |      ~2x       |
| large  |   1550 M   |        N/A         |      `large`       |    ~10 GB     |       1x       |


`.en` models are for English only, and the cool thing is that you can use the `Translate to English` option from the "large" models!

## TODO🗓

- [x] Add DeepL API translation
- [x] Add NLLB Model translation
- [x] Integrate with faster-whisper
- [x] Integrate with insanely-fast-whisper
- [x] Integrate with whisperX ( Only speaker diarization part )
- [x] Add background music separation pre-processing with [UVR](https://github.com/Anjok07/ultimatevocalremovergui)  
- [ ] Add fast api script
- [ ] Support real-time transcription for microphone

### Translation 🌐
Any PRs translating Japanese, Spanish, French, German, Chinese, or any other language into [translation.yaml](https://github.com/jhj0517/Whisper-WebUI/blob/master/configs/translation.yaml) would be greatly appreciated!
