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):

• Azure Text to Speech (Recommended for AI voices)
• Coqui TTS
• gTTS
• pyttsx3
