Manim Voiceover

Manim Voiceover is a Manim plugin for all things voiceover:

Add voiceovers to Manim videos directly in Python without having to use a video editor.
Record voiceovers with your microphone during rendering with a simple command line interface.
Develop animations with auto-generated AI voices from various free and proprietary services.
Per-word timing of animations, i.e. trigger animations at specific words in the voiceover, even for the recordings. This works thanks to OpenAI Whisper.

Here is a demo:

Currently supported TTS services (aside from the CLI that allows you to records your own voice):

Installation

Manim Voiceover can use machine translation services like DeepL to translate voiceovers into other languages. Check out the docs for more details.
