How to do Free AI Dubbing Locally

 This video is a step-by-step tutorial to show you how to do local dubbing with AI by using Elevan Labs free credit.

Code:

#export ELEVENLABS_API_KEY="<>"

#pip install elevenlabs

#pip install python-dotenv

import os

from typing import Optional

from dotenv import load_dotenv

from dubbing_utils import download_dubbed_file, wait_for_dubbing_completion

from elevenlabs.client import ElevenLabs

    response = client.dubbing.dub_a_video_or_an_audio_file(

        mode="automatic",

        num_speakers=1,

        watermark=True,

    )

    dubbing_id = response.dubbing_id
