How to Detect and Censor Profanities

This is an example of how you can use AssemblyAI's Profanity Filter feature to automatically detect profanities and replace them in your audio file.

Quick Setup

• Download project files by running git clone https://github.com/AssemblyAI/profanity-filter-demo.git
• Navigate to the project folder
• Create a new virtual environment
• Activate the new virtual environment and run pip install -r requirements.txt to install project dependencies
• Run the application using the streamlit run profanity_filter.py

How it Works

The YouTube video from the link you submitted is downloaded and then uploaded to AssemblyAI's servers for transcription with filter_profanity set to true. When the transcript is complete, a regex search for all words that start with a letter followed by asterisks identifies the timestamps in the original audio with profanity. The original audio is removed and replaced with the censor of the user's choice.

Main Dependencies
