Installation and Running

On Windows OS

Prerequisite

To run this WebUI, you need to have git, python version 3.8 ~ 3.10, CUDA version above 12.0 and FFmpeg.

Please follow the links below to install the necessary software:

CUDA : https://developer.nvidia.com/cuda-downloads
git : https://git-scm.com/downloads
python : https://www.python.org/downloads/ ( If your python version is too new, torch will not install properly.)
FFmpeg : https://ffmpeg.org/download.html

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

Automatic Installation

If you have satisfied the prerequisites listed above, you are now ready to start Whisper-WebUI.

Run Install.bat from Windows Explorer as a regular, non-administrator user.
After installation, run the start-webui.bat.
Open your web browser and go to http://localhost:7860

( If you're running another Web-UI, it will be hosted on a different port , such as localhost:7861, localhost:7862, and so on )

And you can also run the project with command line arguments if you like by running user-start-webui.bat, see wiki for a guide to arguments.

Docker ( On Other OS )

Build the image

docker build -t whisper-webui:latest .

Run the container with commands

For bash :

docker run --gpus all -d \
-v /path/to/models:/Whisper-WebUI/models \
-v /path/to/outputs:/Whisper-WebUI/outputs \
-p 7860:7860 \
-it \
whisper-webui:latest --server_name 0.0.0.0 --server_port 7860

For PowerShell:

docker run --gpus all -d `
-v /path/to/models:/Whisper-WebUI/models `
-v /path/to/outputs:/Whisper-WebUI/outputs `
-p 7860:7860 `
-it `
whisper-webui:latest --server_name 0.0.0.0 --server_port 7860

VRAM Usages

This project is integrated with 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 the original Open AI whisper implementation instead of optimized whisper, you can set the command line argument --disable_faster_whisper to True. See the wiki for more information.

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!
