How to Use Synthesia.io to Create AI Videos with Talking Avatars

 

Professional Video Creation Without a Camera or Studio

Synthesia.io is a market-leading platform that lets you generate AI videos using lifelike avatars who speak your script in over 120 languages. It’s widely used by businesses, marketers, educators, and content creators to produce tutorials, product demos, training videos, and more — without needing cameras, actors, or editors.


Step 1: Create an Account

Visit the website at synthesia.io.
Click “Create a Free Demo Video” or “Get Started.”
You’ll be prompted to sign up with an email and password, or request access to business plans.

After you log in, you'll enter the dashboard where you can start your first AI video project.


Step 2: Choose a Video Template or Start from Scratch

Once inside, click “New Video.”
You can:

  • Select from professionally designed templates (for training, onboarding, marketing, and more)

  • Or create a video from a blank canvas

Templates help you save time and maintain consistent branding.


Step 3: Write or Paste Your Script

Type or paste your video script in the text box provided.
This is what the AI avatar will say in the final video.

Synthesia supports 120+ languages and a variety of accents and tones, making it easy to localize content for global audiences.


Step 4: Choose an AI Avatar and Voice

Select from 100+ photorealistic avatars — men and women of different ethnicities, ages, and styles.
You can also choose an avatar that aligns with your brand or message.

Next, select a voice:

  • Choose male or female voiceovers

  • Pick from a wide range of tones (friendly, formal, energetic, etc.)

  • Adjust speech speed and pronunciation

You also have the option to create a custom avatar or upload your own voice if you prefer more personalization.


Step 5: Customize the Scene

Use the built-in visual editor to:

  • Add your own text, images, or logos

  • Change the background or use branded color palettes

  • Add slide transitions and animations

  • Insert background music or sounds

  • Control subtitle display

Synthesia’s drag-and-drop editor is simple to use, even for those without any video editing experience.


Step 6: Generate and Export the Video

After finalizing your scenes and avatar script, click “Generate Video.”
Rendering usually takes just a few minutes.
Once complete, you can preview and download your video in MP4 format, ready to publish on your website, YouTube, social media, or internal platforms.
