Upload the voice audio you want the subject to speak. OmniHuman lip-syncs the portrait to the audio.
OmniHuman renders the portrait speaking the audio with lifelike facial animation and natural lip-sync.
OmniHuman v1.5 is ByteDance's specialized image-and-audio-to-video model on Zyka. It animates a single human portrait to speak provided audio with realistic lip-sync and facial motion.
