LTX2.3 Suite 3.5 Talking Avatar Audio Drive

This is an AI digital human singing application based on LTX 2.3, IC LipDub, audio-driven, single-person portrait reference, and third-order high-definition rendering.

Users only need to upload a single-person portrait or character reference image, along with a segment of voiceover, singing, or dubbing audio. The system will then generate a digital human performance video based on the audio rhythm and prompt words.

Unlike ordinary animated portraits, this process incorporates an audio-driven pipeline. The system processes the uploaded audio by performing voice separation, audio trimming, audio duration calculation, and audio latent encoding. Combined with IC LipDub lip-sync guidance, the character performs more naturally in opening its mouth, speaking, or singing based on the audio.

The entire process is automated: portrait image reading, audio uploading, voice separation, audio trimming, audio duration calculation, video frame matching, global prompt reading, segmented performance prompt reading, reverse prompt constraints, first-order lip-sync generation, second-order latent space amplification, third-order high-definition refinement, similarity preservation, final frame trimming, audio reattachment, and final MP4 output.

The final output is a digital human video featuring the original audio, stable character identity, lip-syncing with the audio rhythm, and visuals enhanced through third-order processing.

It is suitable for digital human voiceovers, portrait singing, AI virtual hosts, character dubbing videos, single-character performances, virtual IP promotion, short video voiceover materials, song performances, advertising character videos, and RunningHub video application packaging.

If packaged as a RunningHub application, the core selling point can be directly expressed as:

Upload a portrait and an audio clip to generate a third-order high-definition digital human video that talks and sings with one click.
