⚠️ Never update this OBS. The OBS Real-Time Deduplicator is a special build of OBS Studio with the deduplication tools built in. If OBS shows “New update available”, click Skip Version — never Update Now: updating replaces it with standard OBS and removes the Deduplicator. To stop the prompt: Settings → General → untick “Automatically check for updates on startup”.

3 Major AI Semi-Unmanned Livestream Setup Solutions - Operating Details

1. Real-Scene Livestream + Co-Host Voice Driving

1. Livestream Room Scene

A real-scene livestream is one broadcast in an actual physical setting; this real scene can be a green-screen person, a built set, or a natural real-world environment.

For a real-scene AI livestream, note that the system's Co-Host Voice Driving feature should be used during the stream, with a real person chiming in periodically (every 3-5 minutes is recommended) to ensure the room's audio has variation.

For Douyin, Real-Scene (real person on camera) + Co-Host Voice Driving is the top recommendation.

2. Setup Plans for Different Scenes

2.1 Green Screen Person

In the digital human system, set the livestream type to Real Scene; Livestream Companion goes live using a real camera, with only the real person in the room, acting as the co-host.Codex Image 16 Sept 2026, 18_08_16.png

  • Note! If the background is a video, the video must undergo deduplication

Below is the method for video deduplication: Attachment 1: Video Deduplication Tutorial

2.2 Natural Real-World Scene

A natural real-world scene, as the name suggests, means Livestream Companion goes live using the computer's real camera, with the livestream room set in a natural environment.

To avoid being flagged as a non-real-person livestream or pre-recorded playback due to a static picture or lack of interaction — which could lead to a ban — here are some setup suggestions to ensure the picture has movement and increase authenticity:

  • Swinging clocks/balance ornaments: such as a Newton's cradle, perpetual motion device, or clock.
  • Wind-driven devices: such as a small fan blowing a wind chime, light fabric strips, or dried flower branches.
  • A small desktop fountain: flowing water ripples provide continuous dynamic movement.
  • A humidifier/aroma diffuser: choose a model with a fine, gentle mist output — the slowly rising white vapor greatly enhances the liveliness and atmosphere of the scene.

Below are examples of real-scene setups for different types of livestream rooms:Codex Image 16 Sept 2026, 18_21_43.png

3. Setup Method

  • Select "Real-Scene Livestream" as the livestream typeCodex Image 16 Sept 2026, 18_42_23.png
  • Setting up a real-scene livestream room follows the same process as a digital human livestream (both require setting up scripts, interaction, etc.); the only difference is that a real-scene livestream does not require selecting a host avatar. Once the digital human system has finished setting up the livestream room, save and publish, then click Go Live Now.Codex Image 16 Sept 2026, 18_43_11.png
  • If you have a capture card, set the control console's audio to the capture card's audio; if you don't have a capture card, set the control console's audio to the virtual sound card.

Capture card audio device names usually start with "UGREEN" or "HDMI."

  • In Livestream Companion, add the computer's real camera, and select the virtual sound card or capture card audio for the audio source (matching the control console's audio selection).

3.1 Voice Driving

Voice Driving refers to a real person being able to take over the audio at any time during the livestream, allowing the room to output the real person's voice in real time.

Note! Voice Driving can only be used with the V5 avatar — the V2 and V3 avatars cannot use the Voice Driving feature.

Preparation: plug headphones or a microphone into the computer, open the sound settings in the bottom-right corner of the computer, and set the sound input device to the microphone (the input device name recognized varies by computer — check what name your computer recognizes for the microphone device).Codex Image 16 Sept 2026, 18_46_18.png

At the same time, open the computer's sound settings and turn off the microphone monitoring feature. The steps are as follows:Codex Image 16 Sept 2026, 18_47_00.png

Codex Image 16 Sept 2026, 18_49_19.png

Note! Be sure to plug in the microphone before launching the digital human system!! Make sure only one microphone is connected — if multiple microphones are present, turn off the audio for the other microphones!

3.2 Co-Host Voice Driving

In the top-left corner of the control console, click Voice Driving, and in the pop-up window select Co-Host Driving. For the Monitor Microphone option, select the microphone device plugged into the computer. The real person's voice is fed into the livestream room through the microphone, the system recognizes the real voice in real time, and the AI voice automatically "closes its mouth to yield the floor."

After going live, click the "Co-Host Driving" button once and click Confirm — the audio status is monitored automatically throughout the entire livestream, with no other action needed.Codex Image 16 Sept 2026, 18_49_53.png

2. Digital Human + Real-Person Co-Host Real-Time Driving

Digital Human Host + Real-Person Co-Host

Take the image below as an example: the woman on the left is the digital human host, and the man on the right is the real-person co-host. In Livestream Companion, add a real camera, with the real person sitting in front of it. During the livestream, the real person uses the Co-Host Voice Driving feature to chime in in real time (every 3-5 minutes is recommended); the real person's voice is fed into the room through the microphone, the system recognizes it in real time, and the digital human automatically "closes its mouth to yield the floor."Codex Image 16 Sept 2026, 18_51_06.png

2. Setup Method

2.1 Co-Host Voice Driving

In the top-left corner of the control console, click Voice Driving, and in the pop-up window select Co-Host Driving. For the Monitor Microphone option, select the microphone device plugged into the computer. The real person's voice is fed into the livestream room through the microphone, the system recognizes the real voice in real time, and the digital human automatically "closes its mouth to yield the floor."

After going live, click the "Co-Host Driving" button once and click Confirm — the audio status is monitored automatically throughout the entire livestream, with no other action needed.Codex Image 16 Sept 2026, 18_53_11.png

Supports two setup modes, "One-to-One" and "One-to-Many," to meet different scale requirements:

One-to-One: one real-person host works together with one digital human assistant. The digital human can handle standard content delivery (such as explaining terms or analyzing cases), and when a personalized or complex question arises, the real person can seamlessly step in and answer directly — achieving a perfect combination of automation and expertise.

One-to-Many: one real-person host can appear in multiple independent digital human livestream rooms simultaneously. Each room is equipped with its own dedicated digital human avatar, voice, products, and script, allowing simultaneous operation across multiple categories such as local-life services, e-commerce sales, and lead generation — boosting operational efficiency.

Currently, customer testing shows no issues with one real person appearing in 3-4 livestream rooms simultaneously; further data will require additional testing during actual livestreams.

3. Digital Human + Real-Person Host Real-Time Driving

1. Livestream Room Scene

Only the Digital Human Host Appears

Only the digital human host is shown — the real person doesn't need to appear on camera, and only needs to chime in and take over from the backend at any time (every 3-5 minutes is recommended); the real person's voice will be precisely matched to the digital human's lip movements in real time.

2. Setup Method

See the Syntopia Digital Human Client Operation Manual for how to set up a digital human livestream room

2.1 Host Voice Driving

In the top-left corner of the control console, click Voice Driving, and in the pop-up window select Host Driving. For the Monitor Microphone option, select the microphone device plugged into the computer. The real person's voice is fed into the livestream room through the microphone, the system recognizes the real voice in real time, and the real person's voice is precisely matched to the digital human's lip movements in real time.

After going live, click the "Host Driving" button once and click Confirm — the audio status is monitored automatically throughout the entire livestream, with no other action needed.
