Does LTX 2.3 generate audio, or does it only lip sync supplied audio?

I know this is a stupid question, but I can't find a definitive answer. I was under the impression that it generated audio and lip synced what it generated, but multiple sources (mostly AI) have said it can only lip sync whatever audio you upload into the video. While I'm at it, can anyone recommend a good workflow for experimenting with LTX 2.3 on a 3080Ti (12GB)? submitted by /u/0260n4s [link] [comments]
