wscribe is yet another easy to use front-end for whisper specifically for transcription. It aims to be modular so that it can support multiple audio sources, processing backends and inference interfaces. It can run both on CPU and GPU based on the processing backend. Once transcript is generated, editing/correction/visualization of the transcript can be done manually with the wscribe-editor.

It was created at sochara because we have a large volume of audio recordings that need to be transcribed and eventually archived. Another important need was that we needed to verify and manually edit the generated transcript, I could not find any open-source tool that checked all the boxes. Suggested workflow is generating word-level transcript(only supported in json export) and then editing the transcript with the wscribe-editor.

Currently, it supports the following. Check roadmap for upcoming support.

• Processing backend: faster-whisper
• Audio sources: Local files (Audio/Video)
• Inference interfaces: Python CLI
• File exports: JSON, SRT, WebVTT

These instructions were tested on NixOS:Python3.10 and ArchLinux:Python3.10 but should work for any other OS, if you face any installation issues please feel free to create issues. I’ll try to put out a docker image sometime.

• WSCRIBE_MODELS_DIR : Path to the directory where whisper models should be downloaded to.

export WSCRIBE_MODELS_DIR=$XDG_DATA_HOME/whisper-models # example

• Recommended way for downloading the models is to use the helper script, it’ll download the models to WSCRIBE_MODELS_DIR.

  cd /tmp # temporary script, only needed to download the models
  curl https://raw.githubusercontent.com/geekodour/wscribe/main/scripts/fw_dw_hf_wo_lfs.sh
  chmod u+x fw_dw_hf_wo_lfs.sh
  ./fw_dw_hf_wo_lfs.sh tiny # other models: tiny, small, medium and large-v2
      

You can download the models directly from here using git lfs, make sure you download/copy them to WSCRIBE_MODELS_DIR

Assuming you already have a working python>=3.10 setup

pip install wscribe

• [X] faster-whisper
• [ ] whisper.cpp
• [ ] WhisperX, diarization is something to look forward to

• [ ] Add support for diarization
• [ ] Add translation
• [ ] Add VAD/other de-noising stuff etc.
• [ ] Add local llm integration with llama.cpp or something similar for summary and othe possible things. It can be also used to generate more accurate transcript. Whisper mostly generates sort of a subtitle, for converting subtitle into transcription we need to group the subtitle. This can be done in various ways. Eg. By speaker if diarization is supported, by time chunks etc. By using LLMs or maybe other NLP techniques we’ll also be able to do this with things like break in dialogue etc. Have to explore.

• [-] Python CLI
  • [X] Basic CLI
