Model Files

The OpenAI Whisper models that have been converted to work in burn are available in the whisper-burn space on Hugging Face. You can find them at https://huggingface.co/Gadersd/whisper-burn.

If you have a custom fine-tuned model you can easily convert it to burn's format. Here is an example of converting OpenAI's tiny en model. The tinygrad dependency of the dump.py script should be installed from source not with pip.

# Download the tiny_en tokenizer
wget https://huggingface.co/Gadersd/whisper-burn/resolve/main/tiny_en/tokenizer.json

cd python
wget https://openaipublic.azureedge.net/main/whisper/models/d3dd57d32accea0b295c96e26691aa14d8822fac7d9d27d5dc00b4ca2826dd03/tiny.en.pt
python3 dump.py tiny.en.pt tiny_en
mv tiny_en ../
cd ../
cargo run --release --bin convert tiny_en

However, if you want to convert a model from HuggingFace an extra conversion step is needed.

# Download the repo and convert it to .pt
python3 python/convert_huggingface_model.py openai/whisper-tiny tiny.pt

# Now it can be dumped
python3 python/dump.py tiny.pt tiny
cargo run --release --bin convert tiny

# Don't forget the tokenizer
wget https://huggingface.co/openai/whisper-tiny/resolve/main/tokenizer.json

1. Clone the Repository

Clone the repository to your local machine using the following command:

git clone https://github.com/Gadersd/whisper-burn.git

Then, navigate to the project folder:

cd whisper-burn

2. Download Whisper Tiny English Model

Use the following commands to download the Whisper tiny English model:

wget https://huggingface.co/Gadersd/whisper-burn/resolve/main/tiny_en/tiny_en.cfg
wget https://huggingface.co/Gadersd/whisper-burn/resolve/main/tiny_en/tiny_en.mpk.gz
wget https://huggingface.co/Gadersd/whisper-burn/resolve/main/tiny_en/tokenizer.json

3. Run the Application

Requirements

• The audio file must be have a sample rate of 16k and be single-channel.
• sox. For Mac brew install sox

sox audio.wav -r 16000 -c 1 audio16k.wav

Now transcribe.

# with tch backend (default)
cargo run --release --bin transcribe tiny_en audio16k.wav en transcription.txt

# or with wgpu backend (may be unstable for large models)
cargo run --release --features wgpu-backend --bin transcribe tiny_en audio16k.wav en transcription.txt

This usage assumes that "audio16k.wav" is the audio file you want to transcribe, and "tiny_en" is the model to use. Please adjust according to your specific needs.

Enjoy using Whisper Burn!
