LTX-2.3's voice prior ignores accent requests in exactly the regions where you need them most — young female characters default to Australian-leaning voices even when the prompt says "in a casual American accent". This LoRA turns that wording into a reliable control. ## Read this first: the 24 fps rule This LoRA cannot help you at the wrong frame rate. LTX-2.3's joint audio-video prior is 24 fps-native, and render fps is a hidden accent dial: at 25 fps the same prompt and seed render non-rhotic southern British, at 30 fps broad Australian — and off-24 fps **overrides accent wording entirely**, LoRA or no LoRA. Set your workflow's fps/frame_rate to **24**, then use this LoRA. (Dose-response verified by A/B on identical configs, 2026-07-30.) ## What it does — measured A/B matrix on the hardest region (young pale-skinned woman, casual camcorder monologue), 24 fps, two seeds per cell, blind phonetic review: | spoken-line wording | without LoRA | with LoRA @ 1.0 | |---|---|---| | no accent stated | Australian | Australian | | "saying in a casual American accent" | Australian (both seeds) | **General American (both seeds)** | | rich scaffold ("her voice is a low American voice with a slight rasp, speaking in a casual American accent") | Australian (both seeds) | **General American** | The pattern: the LoRA does not force American unconditionally — it makes the model **obey the accent you ask for** in regions where the base model refuses. State the accent on every spoken line ("in a casual American accent"); the LoRA does the enforcing. ## Lip-sync safe by construction 1,152 LoRA tensors, all of them in the audio branches — `audio_attn1` (480), `audio_attn2` (480), `audio_ff` (192). Zero video tensors, zero cross-modal (`video_to_audio` / `audio_to_video`) tensors. Video content, faces, and lip motion are mathematically untouched. ## Usage - Strength **1.0** in any LTX-2.3 LoRA loader. Verified in long multishot production runs alongside a video-branch...
