monkeyplug 2.0.1

monkeyplug is a little script to mute profanity in audio files.

monkeyplug

monkeyplug is a little script to mute profanity in audio files (intended for podcasts, but YMMV) in a few simple steps:

1. The user provides a local audio file (or a URL pointing to an audio file which is downloaded)
2. Either Whisper (GitHub) or the Vosk-API is used to recognize speech in the audio file
3. Each recognized word is checked against a list of profanity or other words you'd like muted
4. ffmpeg is used to create a cleaned audio file, muting the objectional words

You can then use your favorite media player to play the cleaned audio file.

If provided a video file for input, monkeyplug will attempt to process the audio stream from the file and remultiplex it, copying the original video stream.

monkeyplug is part of a family of projects with similar goals:

• 📼 cleanvid for video files (using SRT-formatted subtitles)
• 🎤 monkeyplug for audio and video files (using either Whisper or the Vosk-API for speech recognition)
• 📕 montag for ebooks

Installation

Using pip, to install the latest release from PyPI:

python3 -m pip install -U monkeyplug

Or to install directly from GitHub:

python3 -m pip install -U 'git+https://github.com/mmguero/monkeyplug'

Prerequisites

monkeyplug requires:

• FFmpeg
• Python 3
  • mutagen
  • a speech recognition library, either of:
    • Whisper
    • vosk-api with a VOSK compatible model

To install FFmpeg, use your operating system's package manager or install binaries from ffmpeg.org. The Python dependencies will be installed automatically if you are using pip to install monkeyplug, except for vosk or openai-whisper; as monkeyplug can work with both speech recognition engines, there is not a hard installation requirement for either until runtime.

• VOSK
  • oci.guero.top/monkeyplug:vosk-small
  • oci.guero.top/monkeyplug:vosk-large
• Whisper
  • oci.guero.top/monkeyplug:whisper-tiny.en
