Manim Speech

Manim plugin for adding speech to videos.

Special thanks to osolmaz and others who worked on Manim Voiceover, which Manim Speech is heavily based on.

Installation

Manim Speech can be installed via pip using the following command:

pip install "manim_speech[*optional_dependency_sets*]"

Where *optional_dependency_sets* is a list of optional dependency sets for Manim Speech.

Features

• Adding AI-generated voiceovers to Manim animations.
• Translating text between languages.

Services

Note: Translating to Traditional Chinese (zh_tw) using the DeepL service requires the chinese optional dependency set to be installed.

Usage Examples

Creating a basic scene with a voiceover with Manim Speech:

import manim
import manim_speech
from manim_speech.services import openai as openai_service

class MeaningOfLife(manim_speech.VoiceoverScene):
    def construct(self) -> None:
        self.set_tts_service(openai_service.OpenAITTSService())
        self.set_stt_service(openai_service.OpenAISTTService())

        with self.voiceover("What is the meaning of life?") as speech_data:
            txt = manim.Text("The meaning of life is 42.")
            self.play(manim.Write(txt), run_time=speech_data.duration)
            self.wait_for_voiceover()
            self.play(manim.FadeOut(txt))

The same scene, but translated into Traditional Chinese:

import manim
import manim_speech
from manim_speech.services import openai as openai_service
from manim_speech.services import deepl as deepl_service

class MeaningOfLife(manim_speech.VoiceoverScene, manim_speech.TranslationScene):
    def construct(self) -> None:
        self.set_tts_service(openai_service.OpenAITTSService())
        self.set_stt_service(openai_service.OpenAISTTService())
        self.set_translation_service(deepl_service.DeepLTranslationService())

        self.translate(__file__, "meaning_of_life", "en", "zh_tw")
        _ = self._

        with self.voiceover(_("What is the meaning of life?")) as speech_data:
            txt = manim.Text(_("The meaning of life is 42."))
            self.play(manim.Write(txt), run_time=speech_data.duration)
            self.wait_for_voiceover()
            self.play(manim.FadeOut(txt))
