vosk-cli

This python package serves as an Vosk interface for Opencast. It allows to generate subtitles (WebVVT files) from Video and Audio sources via Vosk.

Installation

1. Install vosk-cli

Clone this project and run

python setup.py install

2. Install dependencies

  • FFmpeg
  • pip install -r requirements.txt

3. Download the language model

Go to https://alphacephei.com/vosk/models and download at least the English language model.

Unzip the folder of the language model into /usr/share/vosk/language/***, and rename the folder from *** to eng for example. Please use 3 digit language codes for the directory name. The default and fallback language directory of vosk-cli is eng. The directory name should match the workflow operation field language-code.

Now you are able to run vosk-cli -i <input_file_path> -o <output_file_path> -l <3_digit_language_code>.
