Personal Avatars are animated using an advanced form of looping technology called auto-alignment, which understands the difference between when an avatar is talking and when it is silent, and coordinates the body movements in a way that is more responsive to the content of the script.

We’ve reused the same technology powering our Expressive Avatars to achieve better lip-sync and a more natural voice compared to other custom AI avatars.

Personal Avatars also come paired with your cloned voice which allows your avatar to communicate in over 30 languages.

Voice isolation

When recording or uploading a footage for your Personal Avatar, Synthesia isolates your voice and removes background noise in order to ensure optimal voice quality.

Create a Personal Avatar

To create a Personal Avatar:

1. Add footage of yourself that will be used to generate your avatar in one of two ways:
   1. Record yourself using your webcam
   2. Upload a video of yourself directly
2. Record a consent video to acknowledge that Synthesia has the right to create your personal avatar
3. Submit your recording, and your avatar will be ready in 24 hours

🚧

The consent video must be recorded live, and it must be the same person in the Personal Avatar creation footage.

You cannot upload a pre-recorded consent video; it must be recorded live, even when uploading pre-recorded footage to create your Personal Avatar.

Supported languages

The supported languages for recording yourself are:

Arabic, Bulgarian, Croatian, Czech, Danish, Dutch, English, Filipino, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Malay, Mandarin (Simplified/Traditional), Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Tamil, Turkish, Ukrainian, Vietnamese.

Whether you record yourself in-app or upload pre-recorded footage, you'll be prompted to choose a default language for your Personal Avatar. Your voice will be cloned during the Personal Avatar creation process, and you'll be able to use your Personal Avatar in any of the supported languages listed above.

Length

Record yourself in any of the supported languages, speaking as though you're having a natural conversation about anything. What you’re saying while recording should have a clear beginning and end. This is a good opportunity to talk about a recent trip or event, or share your favourite anecdote. The more expressive you are, the better your Personal Avatar will be, but don't forget to include pauses while you're speaking. You should pause for a split second every 2-3 sentences, and between 3-5 seconds when you're switching topics.

To upload pre-recorded footage:

1. Click on + Create avatar in the Avatar page
2. Select Personal Avatar
3. Watch the overview video with the best practice then click Next
4. Select Upload
5. Upload your pre-recorded footage

8. Submit your recording

Personal Avatar guidelines

To ensure your Personal Avatar looks and performs its best, follow these guidelines when recording your footage. These guidelines are applicable to both in-app recordings and pre-recorded footage uploads.

📹 Camera setup

Device

Use your webcam or an external device hooked up to your computer to capture your performance.

If you’re recording yourself using an external device such as your smartphone or a DLSR:

• Plug the device into your computer and select it in the dropdown menu when setting up your recording environment.
• Keep the camera as still as possible to achieve the best results. A tripod helps, but you can use a stack of books if you don't have one available.

Lighting

Opt for natural light from a window, or a strong light source.

• If you're using a professional lighting setup, softbox lighting works best.
• Avoid harsh or top-down lighting.
• Ensure that the lighting in your background is natural and consistent.

Angle

A front facing camera angle is recommended, but you can try varying the degrees for a more interesting angle.

Framing

• Frame yourself from the waist-up if you'll be recording yourself while standing up.
• Frame yourself from just below your chest if you'll be recording yourself while sitting down.
• Make sure the camera is aligned with your eye level–but just slightly above your eye level is alright, too.
• Make sure that you're the only person in the foreground of the video. Synthesia can only create a personal avatar of one person at a time.

👂Audio

Audio for creating your voice clone is captured at the same time as your video footage, so it’s important that the audio from your footage is clear and audible.

Make sure you're in a quiet environment without too much background or ambient noise.

Recording indoors

A condenser microphone in a quiet room will provide excellent sound quality for your voice cloning. However, your laptop microphone will also do a great job as long as you're in a quiet environment.

Recording outdoors

A lavalier microphone is the best choice due to its portability and ability to capture clear audio from the speaker. Look for one with good noise-canceling features to minimise background sounds.

📘

If you're on an Enterprise plan, you can create a custom voice in a controlled environment after creating your personal avatar to use in your Synthesia videos.

🖼️ Background

• Try to avoid backgrounds that might blend into your Personal Avatar.
• Add a plant or two, or include a single-color art piece in the background to add some flair to your scene. The background impacts the emotional tone of your videos and set the mood for your audience.
• Include some light and unobtrusive movement in the background, such as a colleague working at their desk. This will add depth to your scene and make your Personal Avatar look even more natural.

🎙️Performance

Movement

• Avoid sudden and/or extreme movements. Holding a prop like a pen, book, or mug can help you minimize extreme movements.
• Don't cover your face with your hands or any props you might be holding, and avoid resting your forearms on the table (if you're sitting at one).
• Maintain eye contact with the camera.
• Sitting or standing still while recording will capture the best results, but you can incorporate some subtle movement for more natural and dynamic results.

Speech

• Speak naturally and clearly.
• Take a breath in-between paragraphs and close your mouth when you breathe or pause.
• Be expressive and happy for a more engaging personal avatar.

Deleting a Personal Avatar

It's easy to delete your own Personal Avatars and voices yourself, so feel free to experiment while creating them.

To delete a Personal Avatar:

1. Navigate to the Avatars page from the Assets section.

2. Find your Personal Avatar in the My Avatars section.

3. Click on the 3-dot button in the top-right corner of the Personal Avatar and select Delete from the drop-down menu

   

4. A dialog prompting you to confirm your decision will appear. Type "DELETE" in the text field and submit your confirmation to delete the Personal Avatar.

❗️

This will permanently delete the Personal Avatar and all data associated with it.

This action cannot be undone.

Privacy and security

Our platform uses encrypted data transmission and secure storage on AWS to protect your personal information and ensure that your Personal Avatar is protected from misuse.

We always obtain consent before generating an AI avatar and give avatar owners full control over their avatar's usage, including the ability to request that their data be deleted from our platform at any time.
