Structure VoiceNet dimension guide

Rhythm & Timingcode vn_STRUslot 47
This dimension measures the macro-level organisation of ideas within the clip. Below: the merge-scaling dose-response for the __high and __low LoRA (laion/moss-voicenet-dimension-loras) at 25/50/75/100/125%, the measured target value at each dose, the top-3 ± correlated EmoNet emotions and VoiceNet dimensions, three audio samples per dose, and a grounded prompting tip. Costs are shifts vs. the 24-sample neutral baseline in genuineness, vocal-burst blend and speech quality.

Structure controls the macro-level organisation of ideas within the clip. The __high LoRA shifts it +0.22 at 125% (worst cost: genuineness -0.05); the __low LoRA shifts it -0.18 at 100% (worst cost: speech quality -0.27). The __high direction is the stronger, more reliable knob here.

Merging Structure __high pushes the dimension: at the recommended 125% dose the measured Structure score moves from a 0.27 baseline to 0.49 (a +0.22 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is nearly free — the biggest hit is to genuineness (-0.05); across the board genuineness -0.05, burst-blend -0.02, speech quality +0.15. Emotionally it reads as Contemplation (r 0.38), Emotional Numbness (0.30) and Concentration (0.28), and it moves away from Fatigue/Exhaustion, Helplessness and Relief. On other voice dimensions it co-moves most with Smoothness (0.83), Narrator Style (0.80) and Esthetics (0.80), while pulling down Disfluency, Genuineness and Casual Style. Practical call: merge __high at 100–125%; expect Contemplation and Smoothness to rise and genuineness to fall. If you don’t want Contemplation bleeding in, offset it with a prompt cue toward Fatigue/Exhaustion to keep the structure shift without the side-effect.

Merging Structure __low suppresses the dimension: at the recommended 100% dose the measured Structure score moves from a 0.27 baseline to 0.09 (a -0.18 shift). The dose-response is noisy and non-monotonic — the merge is an unreliable knob here. That reach is a real cost — the biggest hit is to speech quality (-0.27); across the board genuineness +0.04, burst-blend -0.20, speech quality -0.27. Emotionally it reads as Interest (r 0.60), Contentment (0.59) and Hope/Enthusiasm/Optimism (0.58), and it moves away from Distress, Fear and Pain. On other voice dimensions it co-moves most with Esthetics (0.84), Recording Quality (0.84) and Smoothness (0.81), while pulling down Disfluency, Casual Style and Genuineness. Practical call: merge __low at 75–100%; expect Interest and Esthetics to rise and speech quality to fall. If you don’t want Interest bleeding in, offset it with a prompt cue toward Distress to keep the structure shift without the side-effect.
