AI Talking Avatar: Make Any Photo Talk with Lip-Synced Speech

An AI talking avatar is a video in which a still photo of a face speaks an audio track, with the mouth, jaw, eyes and head moving in time with the words. On VdoBloom you upload one portrait and one audio file, pick a model, and the tool renders a lip-synced talking video in your browser. No camera, studio or on-screen talent is involved.

Is it free? New accounts get 10 free credits, which covers a short test of about three seconds on Kling Avatar Standard. Real clips are priced by the length of your audio: 32 credits for 10 seconds on Kling Avatar Standard, 15 credits for up to 12 seconds on Infinitalk at 480p. The exact price appears once your audio is uploaded, before anything is charged. The Lite pack is 300 credits for $19.50 one-time (credits never expire) or $15 a month.

The tab is built for faceless YouTube and TikTok channels, course and training narration, spokesperson-style ads, product explainers and personal video messages: any time you need a person on screen speaking a recorded script without filming one.

How it works

  1. 1

    Choose a model

    Kling Avatar Standard or Pro for long voice-overs (up to 5 minutes), Omnihuman 1.5 for short expressive clips, Infinitalk or WAN Speech-to-Video for budget 480p/720p renders, or Video Lip Sync to re-sync an existing video.

  2. 2

    Upload the portrait

    A clear, front-facing photo in JPEG, PNG or WebP, up to 10 MB. Video Lip Sync takes a source video (MP4, MOV or MKV, up to 500 MB) instead of a photo.

  3. 3

    Upload the audio

    MP3, WAV, AAC or OGG up to 100 MB. The tool measures its length and shows the credit price for that exact clip.

  4. 4

    Describe the delivery (optional)

    A short prompt such as "the woman speaks warmly and nods" steers expression and head motion. It is required for the Kling models and optional for the rest (up to 5,000 characters).

  5. 5

    Generate and download

    The finished clip lands in My Creations. If a job fails, the credits are refunded automatically.

Why use this tool

  • Six talking-avatar engines on one page

    Kling AI Avatar 2.0 Standard (720p) and Pro (1080p), Omnihuman 1.5, Infinitalk, WAN 2.2 Speech-to-Video Turbo and Volcengine Video Lip Sync. Switch engines without re-uploading anything.

  • Long-form audio

    Both Kling Avatar models accept audio up to 5 minutes, long enough for a full lesson segment or explainer in a single render.

  • Billed by the second you actually upload

    The price is computed from the measured length of your audio, not a fixed bucket, so a 14-second line costs less than a 30-second one.

  • Works with any face you have the rights to

    Your own selfie, a consenting colleague, an AI-generated character or an illustrated mascot with a clear face.

  • Re-sync existing footage

    Video Lip Sync swaps the speech on a clip you already filmed, with Lite (faster) and Basic (higher quality) modes.

  • Automatic refunds

    Failed renders return their credits on their own; there is nothing to request.

How much does a talking avatar video cost?

Worked prices for common audio lengths. A dash means the model does not accept audio that long.

  • A full 5-minute voice-over is 954 credits on Kling Avatar Standard and 1,910 on Kling Avatar Pro.
  • Credits from one-time packs never expire; subscription credits reset each billing cycle.
  • Free-tier results carry a VdoBloom watermark; any paid plan or credit pack removes it.

Can I make a photo talk with AI for free?

Partly. Every new account receives 10 free credits, enough for a short test: about 3 seconds of audio on Kling Avatar Standard or Video Lip Sync. Infinitalk and WAN have a 15-credit minimum per clip, so they need a credit pack. Free-tier output plays with a watermark. For regular use the Lite pack (300 credits for $19.50 one-time) covers about 4 minutes of 480p Infinitalk audio or about 90 seconds on Kling Avatar Standard.

I have a script, not an audio file. What do I do?

This tab animates audio you supply; it does not read text aloud. You have two routes. The AI Course Presenter tab takes a typed script, generates the voice-over for you and then animates the photo with Kling Avatar, Omnihuman or Infinitalk, all in one job. Or create the narration yourself in Text to Speech, download it, and upload it here, which gives you the full six-model choice.

What people use AI talking avatars for

The common thread is needing a speaking face without a shoot. Typical uses on this tab:

  • Faceless YouTube and TikTok channels that want a consistent host.
  • Course lessons and internal training narrated by the same presenter every time.
  • Spokesperson-style product ads and UGC-style testimonials (with a consenting face).
  • Explainers and onboarding videos for apps and websites.
  • Multilingual versions: record or generate the line in another language and re-render the same face.
  • Personal greetings and announcements from a profile photo.
  • Bringing an illustrated mascot or AI character to life for a brand account.

Tips for a natural-looking talking photo

Lip-sync engines map mouth shapes onto the face they see, so the input photo matters more than any setting.

  • Use a sharp, front-facing portrait with the mouth closed or relaxed and both eyes visible.
  • Even, soft lighting beats dramatic shadows; avoid hands, hair or microphones covering the mouth.
  • Leave some headroom and shoulders in the frame so head motion does not crop awkwardly.
  • Clean audio with one speaker and no music bed gives the tightest lip-sync. Trim silence at the start.
  • Start with a 10-second line on a budget model, then render the final take on Kling Pro or Omnihuman.
  • Keep the delivery prompt short and physical: tone, nods, smiles. Do not describe a new scene.

Limits: what the avatar tool does not do

Knowing the edges saves credits.

  • No built-in voices on this tab: you upload audio (use the Course Presenter tab for script-to-video).
  • One face per render; it does not animate group photos as a conversation.
  • Maximum audio: 5 minutes on Kling, 2 minutes on Infinitalk and WAN, 60 seconds on Omnihuman and Video Lip Sync. Longer audio is refused before you are charged.
  • It animates the face and head; it does not generate a new body performance, background or camera move.
  • Explicit images are blocked by content moderation, and you need the consent of any real person whose face or voice you use.

Frequently asked questions

How do I make a photo talk with AI?

Open the AI Talking Avatar tab, upload a clear front-facing portrait, upload the audio you want it to say (MP3, WAV, AAC or OGG), pick a model and generate. The AI lip-syncs the face to the audio and adds natural expression and head movement. The finished video is saved to My Creations.

Is there a free AI talking avatar generator?

VdoBloom gives every new account 10 free credits, which is enough for roughly a 3-second test on Kling Avatar Standard. Free results carry a watermark. Longer clips need credits: 10 seconds of audio costs 32 credits on Kling Avatar Standard or 15 credits on Infinitalk at 480p.

How much does an AI talking avatar video cost?

It depends on the model and the audio length. Per 30 seconds of audio: 36 credits on Infinitalk 480p, 96 on Kling Avatar Standard, 191 on Kling Avatar Pro and 324 on Omnihuman 1.5. The Lite pack is 300 credits for $19.50 one-time or $15 a month, and the exact price is shown before you confirm.

How long can a talking avatar video be?

Up to 5 minutes of audio on Kling AI Avatar Standard and Pro, 2 minutes on Infinitalk and WAN Speech-to-Video, and 60 seconds on Omnihuman 1.5 and Video Lip Sync. For longer scripts, split the narration into parts and render each one with the same photo.

Can I type a script instead of uploading audio?

Not on this tab, which animates audio you provide. Use the AI Course Presenter tab to go from a typed script straight to a talking video, or create the voice in Text to Speech and upload the file here.

Can I use my own face as the avatar?

Yes. Upload your own portrait and the avatar will look like you and deliver any audio you give it, which is useful for scaling personal content without recording each video. You can also use photos of other people if you have their consent, in line with VdoBloom's content policy.

Can I make a cartoon, mascot or AI character talk?

Yes, as long as the image has a recognisable face with a visible mouth. Illustrated characters, 3D mascots and AI-generated portraits all work; results are most convincing when the face is front-facing and not heavily stylised around the mouth.

Will the talking avatar look fake?

Realism depends mostly on the input. A sharp, evenly lit, front-facing photo and clean single-voice audio give the most natural lip-sync. Kling Avatar Pro renders at 1080p and Omnihuman 1.5 focuses on expressive motion; budget models at 480p are best for drafts.

What is the difference between a talking avatar and lip sync?

A talking avatar starts from a still photo and generates all the motion. Lip sync starts from an existing video and only changes the mouth to match new audio. This tab covers both: the photo models create a talking avatar, and Video Lip Sync re-voices footage you already have.

Can I use AI avatar videos in ads?

You can use the videos you create in your own marketing, provided you have the rights to the face and the audio. Do not use a real person's likeness or voice without their permission, and follow each ad platform's rules on AI-generated or synthetic media disclosure.
