Introducing InfiniteTalk: Infinite Conversations,Maximum Realism

WaveSpeedAI,Tue Sep 09 2025

Currently, most AI video tools can only generate silent clips. While Google’s Veo 3 has brought lip-sync technology into the mainstream, existing solutions still lack true support for extended interactive dialogue.

That’s why we’re thrilled to announce the launch of InfiniteTalk on our platform—a digital human model capable of natural conversation for up to 10 minutes, even supporting two-person dialogues. Creators can transform static photos into dynamic, lifelike digital humans with a single API call.

Forget Old-School Video Production

Based on a novel sparse frame video dubbing framework, Infinitetalk not only enables incremental updates but also generates infinitely long speaking videos from audio input, achieving precise lip-sync, head movements, body posture, and facial expressions.

Simply upload one (or two group photos) of portrait images and one audio file (or two audio files), and InfiniteTalk can generate realistic digital humans capable of sustained, natural conversations (for up to 10 minutes) — whether for delivering a solo speech or engaging in a two-person dialogue, it can be easily achieved.

Breaking the 10 Second Barrier

To date, widely available AI video generation tools have primarily focused on extremely short clips lasting 5–10 seconds.As video durations grow longer, issues such as distortions, identity drift, and jittering are becoming increasingly prevalent.

However，InfiniteTalk was built from the ground up to overcome these limitations.Unlike existing tools limited to 5–10 seconds, InfiniteTalk extends video generation to 10 minutes—3x longer than leading alternatives.Not only does it support up to 10 minutes of generating videos with stable quality, but it also supports two-person conversations, which is a true milestone for AI-driven video.
