# `ScrAIbe: Streamlined Conversation Recording with Automated Intelligence Based Environment`

`ScrAIbe` is a state-of-the-art,  [PyTorch](https://pytorch.org/) based multilingual speech-to-text framework to generate fully automated transcriptions. 

Beyond transcription, ScrAIbe supports advanced functions, such as speaker diarization and speaker recognition.

Designed as a comprehensive AI toolkit, it uses multiple AI models:

- [whisper](https://github.com/openai/whisper): A general-purpose speech recognition model.
- [payannote-audio](https://github.com/pyannote/pyannote-audio): An open-source toolkit for speaker diarization.

The framework utilizes a PyanNet-inspired pipeline with the `Pyannote` library for speaker diarization and `VoxCeleb` for speaker embedding.

During post-diarization, each audio segment is processed by the OpenAI `Whisper` model, in a transformer encoder-decoder structure. Initially, a CNN mitigates noise and enhances speech. Before transcription, `VoxLingua` dentifies the language segment, facilitating Whisper's role in both transcription and text translation.

The following graphic illustates the whole pipeline:

## Install `ScrAIbe` : 

The following command will pull and install the latest commit from this repository, along with its Python dependencies.

    pip install git+https://github.com/JSchmie/autotranscript.git

- **Python version**: Python 3.8
- **PyTorch version**: Python 1.11.0
- **CUDA version**: Cuda-toolkit 11.3.1


Important: For the `Pyannote` model you need to be granted access in Hugging Face.
Check the [Pyannote model page](https://huggingface.co/pyannote/speaker-diarization) to get access to the model.

Additionally, you need to generate a [Hugging Face token](https://huggingface.co/docs/hub/security-tokens). 

## Usage 

We've developed ScrAIbe with several access points to cater to diverse user needs.

### Python usage

It enables full control over the functionalities as well as process customization.

Some usage examples:

- Usage of `AutoTranscribe`, core of the transcription system, for performing trancription and diarization of audio files.

```python
from scraibe import AutoTranscribe

model = AutoTranscribe()

text = model.transcribe("audio.wav")

print(f"Transcription: \n{text}")

```
- Usage of `Diariser`, responsible for identifying
and segmenting individual speakers from a given audio file.
 
```python
 from scraibe import Diariser

model = Diariser.load_model()

diarisation_output  = model.diarization("audio.wav")

```
- Usage of `Transcriber`, for transcribing audio files and saving the transcription afterwards.

```python
 from scraibe import Transcriber

transcriber = Transcriber.load_model()

transcript  = transcriber.transcribe("audio.wav")

transcriber.save_transcript(transcript, "path/to/save.txt")

```


Refer to [whisper](https://github.com/openai/whisper) and [payannote-audio](https://github.com/pyannote/pyannote-audio) for further options.

### Command-line usage

You can also run ScrAIbe in a [Gradio App](https://github.com/gradio-app/gradio)  interface using the following command-line:

	scraibe audio.wav

Some example of important functionalities are:

-  `--task`: Task to be performed, either transcription, diarization or translation into English. Default is transcription.
- `--hf-token`: Personal `Hugging Face` token.
- `--server-name`: Name of the Web Server. If empty 127.0.0.1 or 0.0.0.0 will be used.
-  `--port`: To run the Gradio app. The default is 7860.

- `--whisper-model-name`: Name of the [whisper](https://github.com/openai/whisper) model to be used. Default is `medium`.


Run the following to view all available options:
		
	scraibe -h

### Running a Docker container

After you have installed Docker, you can execute the following commands in the terminal.

```
sudo docker build . --build-arg="hf_token=[enter your HuggingFace token] " -t [image name] 

sudo docker run -it  -p 7860:7860  --name [container name][image name]  --hf_token [enter your HuggingFace token] --start_server

```
 `-p`: Flag for connecting the container interal port to the port on your local machine.
 `--hf_token`: Flag for entering your personal HuggingFace token in the container.
 `--start_server`: Command to start the Gradio App.

Then click the following link to run the app:

http://0.0.0.0:7860

- Enabling GPU usage

```
sudo docker run -it  -p 7860:7860 --gpus all  --name [container name][image name]  --hf_token [enter your HuggingFace token] --start_server
```

## Contributions

We are happy for any interest in contributing and about feedback: In order to do that, create an issue with your feedback or feel free to contact us.

## Roadmap

The following milestones are planned for further releases of ScrAIbe:

- Model quantization   
Quantization to empower memory and computational efficiency.

- Model fine-tuning  
In order to be able to cover a variety of linguistic phenomena.

For example, currently ScrAIbe is able to transcribe word by word, but ignores filler words or speech pauses. 
These phenomena can be addressed by fine-tuning with the corresponding data.

- Implementation of LLMs   
One example is the implementation of a summarization or extraction model, which enables ScrAIbe to automatically summarize or retrieve the key information out of a generated transcription, which could be the minutes of a meeting.

- Executable for Windows
