How to Make Two People Sing Together with AI

Search "AI duet" and you'll find two very different tools: one generates AI vocal harmonies, the other merges two photos into one scene where both people lip-sync together. This is the second kind.

What "Two People Singing Together" Actually Means Here

Duet Karaoke Mode is one of three Karaoke Modes on singingphoto.ai, alongside Solo (one photo) and Pet Karaoke (animal photos). With Duet, you upload two separate photos, say, one of you and one of a friend, or two photos of family members who've never actually stood in the same room, and the AI merges them into a single scene, then lip-syncs both faces to the same song at once.
That's an important distinction to get right before you start: this doesn't add a second vocal track, doesn't generate harmonies, and doesn't "clone" anyone's singing voice. It takes the song's audio as-is and animates two faces to move along with it inside one composited scene. If what you actually want is an AI-generated harmony or a backing vocal added to a track, that's a different category of tool entirely, and this walkthrough won't get you there.

Before You Start

You'll need two photos and one song. The two photos should each show a face clearly: a straight-on or near-straight-on selfie or portrait works better than a group shot, side profile, or a photo where the face is partly obscured. The song can be one you already have, or one made with an AI music tool; singingphoto.ai handles the lip-sync side, not the songwriting.
The one non-negotiable part: both photos need to be yours to use, a photo of yourself, a photo of a friend or family member who's given you the go-ahead, or one you otherwise hold the rights to. Don't use a photo of someone who hasn't agreed to be turned into a singing video, and don't use a stranger's photo pulled from the internet. That boundary applies to both people in the duet, not just the one uploading.
It's also worth deciding where you're planning to share the finished video before you start, since that shapes how tightly you'll want both faces framed in the source photos. Something headed to TikTok, Instagram Reels, or a group chat is usually watched small and vertical, so faces that read clearly at a glance matter more than they would for a video meant to play on a bigger screen.

How to Make a Duet Video With singingphoto.ai

  1. Step 1

    Select Duet Karaoke Mode

    From the three Karaoke Modes, choose Duet rather than Solo or Pet Karaoke. This tells the tool you're merging two photos into one scene rather than animating a single subject.
  2. Step 2

    Upload both photos

    Add the first photo, then the second. Each one should be a clear, mostly front-facing shot of one person (or one pet, if you're pairing a person with an animal). You can reuse a photo you've uploaded before through Asset Management instead of uploading it again from scratch.
  3. Step 3

    Choose the song

    Bring in the audio both subjects will lip-sync to. This is the shared soundtrack for the whole scene: both faces sync to the same song, not two separate parts.
  4. Step 4

    Pick a stage preset, or build a custom scene

    Instant Stage Presets (Studio, Jazz Club, Home, Bar, Supercar, Fisheye) give the merged duet a one-click backdrop with no prompt needed. If none of the six fits what you're picturing, Custom Scene Editing lets you write a prompt describing the stage, lighting, camera, setting, or atmosphere instead, layered on top of what the presets offer rather than replacing them.
  5. Step 5

    Generate and review

    Let the AI render the composite. Since two separate faces are being merged and synced at once, it's worth a full watch-through before exporting, mainly to check both faces read clearly in the finished frame.
  6. Step 6

    Export

    Download the finished video in HD, with no watermark and no paid tier gating any part of the export. That's true of every mode on singingphoto.ai, not a duet-specific perk.

A Few Things That Help a Duet Look Right

The steps above will get you a finished video, but a few habits noticeably improve how convincing the merge looks:
  • Match the framing roughly between the two photos. If one photo is a tight close-up and the other is a waist-up shot, the size mismatch tends to show once they're placed in the same scene. General guidance on merging photos with AI confirms this pattern, photos with similar perspective and scale avoid the "obviously pasted in" look.
  • Similar lighting direction helps more than people expect. A photo lit from the left paired with one lit from the right can read as mismatched once they share a frame. General AI image-blending guidance points at consistent lighting and tone as one of the biggest factors in a believable blend.
  • Higher-resolution source photos hold up better. A blurry or heavily compressed photo has less detail for the AI to work with once it's merged and animated next to a second, clearer face.
  • A face that's mostly unobstructed works best. Sunglasses, a hand near the mouth, or a hat shadowing the eyes gives the model less to lip-sync against.
If you want the deeper version of this, specifically how to pick, crop, and prep the two source photos for the cleanest possible merge, the sibling guide how to create AI duet videos from two photos goes further into that mechanics-first territory. This post is the "what is Duet mode and how do I start" version; that one is the "how do I get the merge itself to look clean" version.

Ideas for Who to Duet With

A few common, low-effort starting points, using generic scenarios rather than any real named person:
  • A couple doing a duet of the song from their wedding or first date.
  • Two friends recreating a duet from a movie or musical.
  • A parent and a now-grown kid singing a song from the kid's childhood.
  • Two coworkers doing a joke duet for a team celebration.
  • A person and their pet, using Duet mode's cross-species pairing rather than Pet Karaoke alone.

Common Questions

Is this the same as an AI vocal-harmony or AI cover generator?
No. Duet Karaoke Mode merges two photos into one visual scene and lip-syncs both faces to the same song. It doesn't generate a second vocal part, a harmony, or an AI-sung cover. If you're looking for AI-generated harmonies, that's a different kind of tool.
Do both people need to send in their own photo?
Yes, functionally. Duet mode needs two separate photos to merge. Both need to be photos you have the rights to use: your own, or a friend's or family member's with their permission.
Can I duet with a pet instead of a person?
Yes. Duet mode merges any two photos, so a person-and-pet pairing works the same way as a person-and-person pairing. If you only want a pet singing solo, Pet Karaoke is the more direct mode for that.
Is Duet Karaoke Mode free?
Yes. HD export, no watermark, and private generation are free across every mode on singingphoto.ai, including Duet. There's no paid tier gating any of it.
